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

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
