It is not for some odd political or intellectual property issue that Li-ion are prevailing in the marketplace. And some of the formulations probably have more Ni in them than Li, but I don't know that is a fact. If it isn't true weight wise, it is probably true $-wise. Although LiFePO4 have no n

LFP I know about, and they can provide more than 2000 cycles if you make the same sort of effort as one does with Lead. Charge them right, don't run them too low, ask too much of them when they are cold, etc. You can ruin any battery. There is a loss of capacity if LFP just sit, of maybe 1% a ye
