This was 2 years ago, but once they get rolling, I might do this in maybe ALL my power needs, Home, and Motorhome! An Electric Foretravel, anyone? https://www.youtube.com/watch?v=3K8JIC-ov_YBTW, I knew that Elon Musk was Primarily interested in this Tech, in his Grad Studies. He may apply his "Power Wall" in a Supercap Flavor some day.....we can only hope?It might take another 100yrs for the price to come down.. So it is affordable. Quote Selected 1 Likes

What a boon for those of us who love to boondock! Quote Selected 1 Likes
Re: lithium batteries- drop in Reply #52 – February 05, 2019, 09:08:14 pm Supercaps have a low amount of Watt-Hours. E.g. Ten watt hours. BUT, they pack a wallop in instant power. E.g. 2000Amps.I did not buy one because of the price, but I may eventually buy one to start the engine faster in cold weather. Quote Selected 2 Likes

Possible, it's a Let's wait and see, I guess? They have that so called "Proprietary" method to Slowly release those Amps, he "Says"? Quote Selected

Admirable in any measure, check out what I just found, on the Super-Caps, and Possible Acquisition of Maxwell Technologies! This might be a real Game Changer....can you say, chuck the Diesel Tank, On- Board Generator, and Diesel Engine, and have it all? Maybe Keep a Small Diesel Tank, and Larger KWH Genny, for an even longer range? Check this out! Interesting if true!!! https://www.youtube.com/watch?v=H8wdeqS3UlU Quote Selected

Re: lithium batteries- drop in Reply #57 – February 19, 2019, 09:39:39 pm And, for a Real-True, Pie-in-the-Sky, a Tesla TOAD, that not only has Regen Braking, But Regen Mode while being Towed 4 Down! Hmmmmm All good, huh? 4000+ Watts on the Roof, And Imbedded in the 'Glass Gel, on Both sides of the Coach, in full sun would give Great Boondocking capability, as well! Hey, one can dream....Tesla sure can, and does bring Excitement, to our Technological world, without a doubt! Quote Selected

Re: lithium batteries- drop in Reply #59 – February 20, 2019, 06:52:15 am I recommend 20KWH of batteries for our rigs. I did the math.This is about the power of a Nissan Leaf G1 battery pack. Quote Selected
Re: lithium batteries- drop in Reply #60 – February 20, 2019, 10:01:29 am I did the math on this and put in 3 new 8d agm's. I feel alright with my choice We aren't prolific boondockers though and I don't mind the inefficient charging using my little $150 sportsman generator that gets 10 hours on a soda can's worth of gasoline. That said if the Prosine 2.5 fails near end of battery life I'd make the upgrade. For any of those considering anything other than LiFePO4 I wouldn't. People who make the DIY powerwalls out of old laptop batteries (incredibly economical!) sometimes have fires. If I made such a thing I would build it in its own structure. Quote Selected 2 Likes

Make sure you know what your talking about before you claim fires.. Any documents showing a LIFEPO4 fire? Re-read - I was speaking of daring to use other chemistries Most of the people doing DIY powerwalls are using recycled 18650 cells using one of the other more volatile chemistries. If you use lifepo4 you could probably make it work with the xantrex charger and some careful attention. Quote Selected
Re: lithium batteries- drop in Reply #64 – March 09, 2019, 05:27:58 pm Victron charger .. victron controller .. dropped in the batteries and all I do is check the voltage.. but it's a waste of time for me. Batteries have bms and solar. Honestly have done nothing but use them.. so far it's been great . Sorry for the misread .. lifepo4 is the safest way to go.. that I know of. Not sure on the other chemistry Quote Selected 1 Likes
