Big Battery 24v A123 LFP vs. 24V Li-ion Battery Box

[Nica McNeil]

Hi All, Does Will are anyone have any words of wisdom as to which battery is better for Will's 4000 watt-24v off grid system. I'm considering the 24v A123 LFP or the 24V Li-ion Battery Box from Big Battery. I'm thinking LIFePO4 is better but the New Modle 3, 2170 Cells is making me second guess myself even though they are $50 more. Thy seem to be nearly twice the storage of Battleborn at a lower price.

Any of the mentioned systems are workable. There is a SMALL safety margin with LFP vs. Li-NMC. The fact that these are "plug-and-play" systems means they already have BMS and have reduced risk over DIY.

Better is what meets your needs best. Hard to guess. The factors are:

Safety
Capacity
$/kWh
Size
Weight

Decide which aspects are more important and pick your winner.
