Deep cycle systems LiFePO4

Aluminum is found all over the world and not a fire issue , I'd say those are a big deal beyond the cycle issue most other batteries suffer with.

 

My LiFePo4 batteries have been doing a great job for the past several years. Lots faster charging than the lead-acid before and more usable power per charge. So far no degradation even in the Southern heat. At this rate, I anticipate at least ten additional years out of them...which will make the ROI better than if I had chosen lead-acid replacements.
ETA: These are BigBattery Kong Elite Max...19kWh each.

 

I have been using lithium batteries in RVs for some years now.. It has been an opportunity to understand how solar panels work at the same time. I have been very happy with various setups. A big advance from lead acid and even AGM batteries.

 

Especially when it's time to burn it down and collect the insurance.

 

I have been on surplus AGM batteries for the last 6 years. So far they are holding up good. Now that LifePo is getting affordable, will be replacing with them when the old ones take a dump.



I have 4 of the red suitcase style(180ah) and four of the grey(123ah) data storage making up two parallel 48 volt banks. Unfortunately just one new rack battery costs more than all 8 of the AGMs I am using now.
