Battle Born batteries can be mounted in any orientation.  I layed them on their sides and stacked them 3 high.  600aH worth in the space of 2 8Ds.

Does anyone make UL listed li-ion batteries yet?  Other than just the cells?

Just a few minutes to find...

Battle Born Batteries "All of our cells are listed to UL 2054 standards. BB10012 batteries listed to UL2054 standards, IEC 62133 and UN38.3"

Battle Born batteries are LiFePO4, one of several lithium ion types.

Lifeline AGM Batteries " UL Recognition. All Lifeline® AGM batteries meet the requirements of UL® 1989 (Standby Battery) and are UL recognized under UL File Number MH-17983."

Different batteries, different specs.

Here is some newer info from UL

https://msc.ul.com/wp-content/uploads/2018/03/UL_WP_Safety-Issues-for-Lithium-Ion-Batteries.pdf

If someone has a link to the battle born post showing their statement of being listed under various testing standards that would be appreciated.

It does not show on their website or on the batteries themselves.

Did I miss this?

My coach is right at GVWR, so in an effort to shed some weight (around 400 pounds worth) without tossing "my stuff", I followed Roger's lead and took the Battle Born plunge...BB had a good discount going at the Q big tent, which iced the cake to get 6 of the 12v standard packs.  Configured much like Roger's install using buss bars and direct, equal length battery connects, but decided to lay them on their sides and stack them instead of manufacturing a new tray and opted to do the drop in replacement vs. adding a B to B charge controller for now.  The slide wall truss was a pain in the arse to work around during upper rack removal, cleaning, and prep.  Spent a few days getting layout board, and buss board built, but total time power off to replace everything in the battery bay was just 4 hours.  Per BB's tech support advice, placed some of that rv anti skid mat between each battery and strapped them to the rack with cargo straps.  They're not going anywhere.  Sealed up the bottom vent holes and drilled a few holes through to the adjacent aquahot chamber to allow air to circulate in the battery compartment.  It sure was nice to wake up to 13.0 volts the past few mornings!  JWID.

Looks good Woody,
I used the GC2 BB variant because I could get at all of the wiring on all batteries even with the slide truss on out 2001.Easier to secure as well.  The 6 GC2s were very attractively priced which helped.

I cut out most of FRP sheet covering the truss for easier access and painted it all to look nice.

The switch is for the battery heaters and a digital voltmeter too.

With my $10 per battery battery heaters they stay 40° or more above ambient and since they are powered by the batteries themselves the batteries are active which helps keep them charging. 

What was the source for your "$10 per battery battery heaters"?

Battery heaters are designed for snow mobile or motorcycle hand grips.  Come with wiring, heat shrink tubing to mount them on the handle bars and a high/off/low switch.  $5.77 each for six sets now. I got an extra set.  They seem to be working fine, power use is consistent, they were on for more than a month before we headed south.  They attach to the batteries with an adhesive backed foil faced foam pad.  The photo is on the bench set up where I was measuring temperatures.  Final wiring has disconnects in the wiring for each battery and a common set of controls for all of them.  I can measure power use in watts.  Any significant change would tell me if a heater is not working.  These easily keep battery temperatures measured at any of three terminal sensors 40° or more above ambient.

We just finished 52 hours disconnected from all external power other than solar.  We are in TX. One day was very cloudy, one day was sunny.  We are running everything in the coach including the residential refrigerator using only our 600 amp hrs of Battle Born batteries.  At 52 hours we hit 50% SOC. Pretty cool.  I plugged in and turned on the small 40 amp charger. It is going to rain all day Tuesday.

In your picture in reply #31, I see 3 batteries. Are the other 3 behind these three?
