Hello all, I have been researching upgrading to lithium.
Currently I have:
220Ah 12v deep cycle - 2P
AMC12-12-60 which is a 60A DC-DC charger running off my alternator
350w solar panel
30A Epever MPPT
1500W PSW inverter
I am looking to upgrade to lithium as I want more capacity to possibly run an air conditioner and be off-grid longer. The DC-DC can be programmed to work with lithium.
I have picked up 16x 200Ah single cell Lifepo4's that are well used. I want to arrange 4P4S and will be doing proper capacity tests soon but in the meantime, I have some questions.
1. If my cells have a wide variety of capacities, what should I do? Lets say 1 cell has only 150Ah capacity, then the low voltage cut off will trigger after 150Ah is used so not really a problem other than reduced capacity. If this is the case, I am not bothered but if it will damage something, then I should be worried!
2. Is there a device out there that can be a BMS, an active cell balancer and a cell monitor all in one, ideally with bluetooth or a remote display?
3. Any other tips or advice you can give someone new to lithium!
