Hi,

I'm wondering if anyone can provide some guidence about the price point of LifePO4 batterys. .  I'm investigating some 10kWh battery packs.  The pricing being around $3800 USD.

Whats the going price for this battery technology

NiHaoMike:
I paid a little more than $100 or so for 60 32650 cells to make a 12.8V 82Ah pack, but that obviously doesn't include the time needed to assemble the pack.

Did you include battery management hardware?

The BMS is about $10 or so. I modded it similar to what Kerry Wong did for his battery pack, but I put LEDs across the resistors to give a visual indication that balancing is active.

Interesting.  At $100 for a 12V 82AH, its  nearly 1kwhr.    THat would make 10kW, a little mroe than $1000, thats nearly 1/4 of the price of a finshed system.

Now makes me wonder
