The cells cost about $450 delivered. A big BMS (for running a large Inverter) costs $125, for a total of $575.
For a
FIRST LFP battery, you will probably need to buy a few other one-time things:
- 4-6 feet of really big wire (AWG-00, or maybe even bigger than that). This reaches from the battery terminal to the main fuse (in my case a 250A fuse), and also from yur battery bank to your big Inverter. This stuff costs a bit less than $6 per foot.bout , fuseforms the main even A few feet of buch of good
- a bunch of wire lugs, matching your wire size ( aset of 10 costs about $15)
- A sledge-hammer "crimper tool" for those lugs, about $20.
- A small torque wrench, accurate from 15 to 70 inch-pounds (not foot-pounds). Maybe $30.
- And possibly a bench charger, although you can also use your TM charger to "wake up the BMXS and charge it up. $35 if you get one.
- And probably a better TM battery charger. These are expensive, $180 to $250+ (if you want high power AND bluetooth control).
It adds up quickly on the first battery. Additional batteries add only the battery cells, bus bars, fuse, and BMS for each battery.
