More Info:

LFP chemistry.

All cells are very well balanced at 3.295-3.298V. 

There are resistive heaters along the sides of the modules. Total Resistance is 6.3 Ohm. The heater was powered from outside the battery. Each module heater is disconnectable.

The modules are glued down, but with a little work you can get them to come off. The bottom plate has coolant ports, so leaving them glued down would help with cooling.

There are three modules inside this pack, each with 21 cells in series, a total of 63 cells.

Shipping will need to be freight due to the pack size. We can ship this pack to one of our locations for no more than $250, or ship to a commercial address or freight hub near you for $350. Residential freight delivery is possible for an additional charge, contact us for a quote.
