two years with lithium

I just realized it’s been two years since I installed the LiFePO4.

No regrets.

If I’d been somewhere static I could have ordered components and gotten more Ah for less money. But I was on the road.

Prices have continued to fall. If I were doing it today I could buy ~200Ah of LiTime or similar for the same money as the original 100Ah.


I have only run the bank down to BMS cutout once since I’ve owned it; I left some big load running all night (crypto miner?) and woke up before sunrise with no power. Went back to sleep and by the time I woke up solar had the system running again. No harm, no foul.


I am happy with the external warming and would not pay for self-heated if I had to replace the bank today. I’m working on an opinion article on the topic for those contemplating the choice.


The BMS (JBD) seems to consider each use of 80% of rated Ah to be 1 cycle, regardless of how it is consumed. As of right now I’ve had the bank for 740 days of full-time use and the BMS indicates 436 cycles.

This means I’m using about 0.59 “cycles” per day.
