Title: Need Batteries
Post by: 71stpsde on September 24, 2019, 10:35:41 am
So my new to me coach needs batteries. They were installed in 2011. So I need suggestions. Barry had 4 8d batteries in the coach. If I went with 4 8d AGM batteries, it would cost $2800. If I went with 3 Battle Born's, it would be around the same price. I wanted to upgrade to lithium, but in 3 or 4 years. I was going to slowly upgrade the inverter and add more solar in the next few years, but I need batteries now. My question is can I temporally use the Prosine until I get a better one early next year.  I was looking the Prosine owners manual and I don't see custom settings. It looks like it's broken down to flooded and Gel/AGM. I know that you can't equalize lithium. So the Gel setting would be the best setting. Also would adding 3 more Battle Born's in a few years be a problem with the older ones?

Hi ?,

I just installed 6 Battle Born LiFePO4 batteries and the initial instructions were to set the inverter/charger to lead acid. That wasn't set in stone because the owner said you could also set it to AGM also. Just as long as you don 't go over 14.6 VDC it should not harm their batteries. (During installation, use a paper/etc. separators or temporarily use tape on the connectors to keep from shorting the current - Lithium batteries don't like arcing.) I'm using a Victron Battery Monitor and it is set to top out at Froxlor Server Management Panel (http://14.4.in) order to obtain a full charge. I would presume the AGM voltage is still below that. Briefly try your AGM setting and see what the peak charge voltage goes to. Be quick to shut it off it gets to be less than 0.3 Volts below 14.6.

Mike, if you do not want to use LiFePo4 batteries yet consider 6 Full River DC335 6 volt batteries.
DC335-6 | Fullriver Battery (https://www.fullriverbattery.com/product/dc335-6/)
Six will fit on the floor where 2 8Ds now sit.
You will have 1005 amp hr capacity.
You will get rid of extra racks and their weight.
6 of the DC335 weigh lees than 4 8Ds.

If you are not vertically constrained (probably not in your 2003) you can use 4 L16 sized 6 volt batteries. 830 amp hrs.
DC400-6 | Fullriver Battery (https://www.fullriverbattery.com/product/dc400-6/)
Battery upgrade (https://www.foreforums.com/index.php?topic=37569.0)

There are other 6 volt options but FullRiver has the best warranty.

With an electric refrigerator you will probably want 4 tp 6 LiFePO4 batteries.
Bay Marine Supply. DC335-6 | Fullriver Battery (https://www.fullriverbattery.com/product/dc335-6/)  Has good prices on BattleBorn and will discount further for Forum members.

Mike, my personal opinion is go with lithiums. They will last a lot longer, provide more amps for less money over time, at less weight, and with less space.
The initial cost is higher which is why you should save your money and go with lithiums.
I have 600 amps of Victrons and want an additional 300 next year.
The battelborns are nice cause they  have the BMS built in, unlike the victrons which is additional. I trust my victron setup more than the battleborns, but that is just me.
Just make sure you don't try to charge them when the battery temp is less than 35F or so. But the BMS will take care of that.

I was talking to Justin yesterday at Bay Marine and the Victron's can't be drawn down to their capacity as the Battle Born's can. I don't remember the percentage as that was not the reason for my phone call. My 150/85 has gone down. As far as comparing the 4 8d's with 450 usable amps at 50% to three Battle Born's 300 amps at 100% discharge is a choice Mike will have to make along with a better charging system.

Lithium's is my choice, but the inverter/charger won't charge it correctly until I get a newer one. I emailed Battle Born and asked the question. I think it will work until I get a new one. I won't be boondocking anytime soon. I'll be hooked up to 50 amp, but the alternator won't charge while I'm driving until I get the correct BIM. All can be done in due time. I hope that it could hold up until early next year.

Craneman, I'm not sure I would want to draw any battery down to 100%. With Lithiums, you generally expect to go around 80% of total amp hour rating and that should get you several thousand cycles.  Since most of us wouldn't draw it down that low, I expect 5000 cycles or so.  Pulling them down more would cut into that.  But still its a lot more than the 50% or so of agm or LA.
That is where the true  savings with lithium are in terms of money spent. Then there is the weight savings.
Mike the victron inverter charger can be used with lithiums. Or go with solar and victron has mppt controllers that will charge them.
But other manufacturers have stuff that can charge lithiums.

Given the cost of batteries (and the potential to significantly shorten their life if they aren't charged properly), I would strongly recommend biting the bullet and upgrading the inverter before or at the same time as battery replacement.

The Prosine inverter (if it's the OEM one for that coach) is not a repairable model and there have been a lot of advances made in inverters since it's era (as there have been with battery technology).  Some of the newer hybrid offerings are quite appealing, and do be sure to check with Bay Marine (see the Commercial Listings board) for forum-friendly pricing.

Lithium's will take a partial charge or a lower rate of charge without damage or loss of capacity.  So will the oem mk gels.

Other batteries can be damaged from slow or incomplete charging.  Lifeline is the only non gel or lithium battery that can be equalized to restore any lost capacity. 

If you can without fail recharge any drawn down batteries to 100% shortly after use then std agm's will work.

Going from 85 to 100% SOC takes a lot of time so the inverter makers like my heart freedom 25 recommended running the batteries between 50% and 90% to avoid the long charge time to get from 90 to 100%.

Lithium cannot be charged below 34 degrees.  Or used over 104 degrees.

The oem mk's can be not fully charged up to a week or so without apparent capacity loss as a lot of owners reported 10-12 years life.

Agm's need the 1/5th or 1/20th of capacity charging rate  and need to get to 100% almost without fail for the longest life.

Gels and lifeline agm's need to be .2 volts lower than flooded or gels.

A battery temp system is either required or recommended by most battery makers to adjust the voltage based on temps.

Your coach should have that already.

If you have specific questions my local x Foretravel dealer tech friend serviced Barry's coach for many years here and  I can ask him.

The Magnum has a specific program in it for both gels and lifeline agm's and std agm's.  And can equalize Lifelines as a std program.  Not sure about li-ions through a Magnum.

The oem optima red tops(a few yellow) and the mk(east penn) gels have had countless 10 years life reports here.

Before I bought my Battleborns, called the factory and they told me the batteries are actually a bit bigger than 100 a/h's. The BMS will cut them off at 0 SOC but the battery is not completely empty so no damage or major length of life problems, but I do not think very many would go to 0 SOC on a regular basis. I know the BMS works, parked in the shade and left both vent fans and lights on until they shut down.

If you don't want to get a new inverter now (makes sense if you are upgrading batteries) you can get a smart charger.
Sterling ProCharge Ultra 50 Amp Boat Battery Charger (https://baymarinesupply.com/chargers-inverters/sterling/sterling-procharge-ultra-1250.html)
These charge multiple battery banks, using many different charge profiles, are very efficient, sets itself to sleep mode when no charging is  needed.  When we are plugged in all of our charging comes from solar and from one of these.  The big inverter and charger are off.  We have a 40 amp one and it has no problem keeping up.

Charging and using LiFePO4 batteries when ambient temps are below minimum temperatures is easy if you add some supplemental heat.

I agree for the most part and depending on what brand of lithium or how its manufactured.. Lie Jcus mentions .. some have a built in reserve.. so the 100% isnt really 100% draw down. My batteries are 1200ah but I can get 1400ah if I push the limits.

As for what Michelle said.. I would replace the Inverter/charger now as it is going to fail like the rest have and with no real benifit to keep it.. Old is old is old... Waste of money to try and fix .. even if you could.

Or like mentioned you could add solar to do the charging and depending on where you are at most of the time it might not work for you without a massive amount or so.. You can also buy a lithium battery charger but by the time you buy it you might have been a head to put the money towards the inverter needed.

Mike, I actually have it set for flooded lead batteries and for warm setting.  This gives me a max voltage of 14.4 and float of 13.5
You'd need to verify these settings yourself.
I seldom leave the charger running on float, usually get it to 80 or 90% then turn it off.  The solar does a good job of maxing out the charge.

A battery temp system is either required or recommended by most battery makers to adjust the voltage based on temps.

Actually Victron is +5 C to +50 C or 41-122 degrees F.
battleborn claims a 25-135 F. I would be very cautious about that. Temps below 32 deg F have killed lithium ion batteries when charging them. Either way the BMS will control this and shut off charging at that point.
That is temp at the battery, not outside temps.
Victron has a higher temp requirement due to it's fast charging ability. My batteries could take 600 amps,if I could deliver that, but likes 150 amps or less. Hooked up to a 50 amp circuit and with full solar, I should be able to deliver that.

Bottom line Mike is if you can afford the lithiums, go with it. If you can't, then AGM or Gel is the way to go now.  However, any battery system has to be charged correctly to get the full capacity and life span with them. If your mostly going to be hooked up to shore power at 50 amps, then you just need the juice to get it from place to place, and then you don't need much. 600 amps of AGM will get you 300 amp hours of usable capacity, and if your mainly traveling only occasionally, you can use the alternator and/or generator to charge them.
victron agm (https://shop.pkys.com/Victron-Energy-12V220Ah-AGM-Deep-Cycle-Battery_p_3917.html) these will get you 220 amp hours of usable capacity and cost just over 1 coach buck, and if you take care of them, last a while.
Then when you want to boondock more, you can consider upgrading to lithium and use these for your start batteries.... or sell them and get some of your money back. 
Title: Re: Need Batteries
Post by: jcus on September 24, 2019, 11:20:12 pm
I had the Prosine when I first bought my Battleborns. [Got the Victron Multiplus as soon as I could afford it]  Couldn't really set it up properly for lithium, but if you are not boondocking, would just run the prosine until battery voltage about 14.2 or so, then shut it off till battery falls to about 13.2, then turn on charger again, and back off at 14.2. Unlike gel and agm, battery state of charge is not important and can sit at anything between 0% and 100% for as long as you want with no worries. No equalization and will automatically balance cells when you fully charge them. Once you get solar, might not even need your inverter to charge anymore.
As mentioned before, Justin or Alan are the experts at Bay Marine Supply and are happy to explain your options. I park in the shade now, so not much solar and about 80 watt parasitic load all time. I turn on inverter and charge to 90% SOC [about 14.4 volts] and shut it off. Then come back in 4 or 5 days and battery is down to 30% or so, 13.2 volts. Charge it up to 90 again and shut it off.

Been in 100+ degree temps
Have 300 watt dedicated inverter in overhead for all the audio/video. I leave it on 24/7 for days while dry camping
Rarely run the gen set. Has 800 hrs on it.
All three, right at $700.00 with tax and exchange out the door.
At this price, I can replace my batts every 3 years and still be ahead.
Totally happy with them

Are they located in a vented bay rather than the "belly" secret compartment in the middle of the coach?

If they are in that inboard/centerline compartment behind the wall of a regular bay, the absolutely should not be flooded batteries.  If they are in a regular bay, that bay must be vented.

Gels and AGMs can go in that inboard compartment.  I don't know enough about them to say for sure, but I would think LiFePO4 would also be OK in that compartment.

In our previous rig, dry camping for 4 years we used 6 DEKA 6V batteries and a PD 9620 to keep them topped up.  We found they needed to be watered every 6 months.  The PD 9620 is has voltages fixed at 14.4 Bulk Charge, 13.6 Absorption Charge and 13.2 for Float.  Once a day the fixed program boosted the charge voltage up to 14.4 for 15 minutes to stir the electrolyte.

Our U225 came with a PD 9160 running 13.6V steady and I added the outboard charge controller to achieve the same functionality as the 9260.

I'm thinking of adding another PD 9260 just for the chassis battery, a flooded cell 8D, partly because I'm a belt and suspenders sort of guy and like the idea of having 60A available just in case the engine driven alternator goes belly up.

Both of Oreillys Superstart (most of their batteries are called superstart, it is just their trademark) 8d batteries have caps, atm and wet cell.  The way to tell the difference is that the agm 8d made by East Penn has a grey case with a black top.  The wetcell is entirely black.

Mike, AGM's have caps also, but I am pretty sure when we were considering Barry's coach, those were AGM in his coach.  I am also interested in going solar eventually, just not sure I want to spend the money for lithiums, however, they are starting to come down in price as more vendors get into this technology.  I have had good luck with gels in the past and will most likely keep them when we upgrade to solar, until needing replacement.  We also don't have the Prosine anymore, it was upgraded to the Xantrax.

Mike, with a residential refrig your daily power usage is somewhere around 3000 watts, maybe more.  That is going to be about 240 amp hrs per day at 12.5 volts.  A good rule of thumb practice for AGM batteries is to try to stay at 70% SOC or higher to maximize life cycles.  That means you need at least 800 amp hrs of battery capacity.  3 8Ds in the best of shape might be 750 amp hrs.  Increasing battery capacity no matter what batteries you use would be prudent.  If the LP tank is gone you probably have room for 6 L16 sized 6 volt batteries, 1245 amp hrs.  4 would be an easy fit and give you 830 amp hrs.

Barry put in 4 8D AGM batteries at 250ah each. I think the problem might be that MOT hasn't had the coach plugged in. When I was in it 3 weeks ago, the digital gauge on the dash said 13.6 volts. The problem is I'm not at the coach. I'll be there tomorrow afternoon.  Keith said he would check the batteries and the charger.

I agree with Chris. And I like to keep things simple. Wether you buy batteries at Napa or Orlieys  doesn't matter. If your old batteries lasted that long then new ones should last just as long. Why spend money on items needed for new age batteries. To me it doesn't make could sense. But everybody has there opinion.

I wasn't putting anyone down for wanting to do these huge expensive battery, inverter/ charger upgrades. I just can't personally justify dumping that kind of money into a 15-20 year old coach, when all the original stuff works pretty darn good. Just showing there are alternatives that work good.

I agree with Joeszeidel, sometimes simple is better.

Might as well buy a big dollar razoo coach, with all the blue tooth,whistles and bells. I guess I am old school.

But I have a saying about Hot Rods and custom cars, when other people put someone's down. It's their car and they like it, so I like it.

BTW, Napa,East Penn and Deka, are made by the same company. There are very few battery companies in the USA. I believe 2 or 3. Don't quote me.

Cheers
Chris

As I replace and upgrade by batteries, I've chosen, after my reading, Interstate because Interstate is upfront with their numbers.

As far as people and their cars, years ago we used to attend a Wednesday night car cruise in Worcester, MA and one night we took the Challenger.  The guy next to us raised a stink because "I put $7,500 into my duster and you let that rat park next to me!"
I said "I'm sorry."  He said "You should be."  I said "No, I'm sorry you put $7,500 into that Duster and all you have is a Duster."
Management asked us to leave.  Most everyone else recognized Lynn's car, a 1 of 7 Dodge Challenger 440 6-Pack R/T Convertible, a Chrysler Corp. dealer promotional model that was all original including it's burnt California interior.

Interstates are made by Johnson Control who bought them out. I could not find Interstate 8D's in production, only 4D's. The ones I found were old stock.Napa's had great reviews.I do/did like Interstates.

The Interstates at Costco (while good), are NOT the same interstates you get at a Interstate dealer. My wife works for Costco, ask any Interstate dealer. Better yet, pick each one of them up. Proof will be in the weight.

Have 25K just in our Dusters engine. Feel free to park next to me anytime, or better yet, pull up next to me at any stop light!  ;D

Cheers

I'll pick my next and last battery up at the local Interstate distributor.  That'll bring me up to snuff for now.
Right now the Siata project is dragging on longer than I expected, but the end is in sight.

Knowing that the battery was manufacturer by East Penn of Johnson is only part of the equation.  To whose specification the battery was manufactured is the other.  I hate buying batteries.
