Hi Max22 If you have the 8 pin connector with 6 wires that was plugged into the balance board the wires are: Red (V+) DC Supply (I have used 7-12vdc) Black (V-) White (CANH) CAN Bus Yellow(CANL) Brown(CANH) CAN Bus (same as above.) Blue(CANL) Using a raspberry pi with a CAN transceiver...

The BMS requires a seperate dc supply (I think the main micro-controller came to life when the supply hit 6 or 7 vdc but have used 12v.) The board spits out CAN bus messages with encoded cell voltage (3 messages with binary codes for 4 cell voltages each) shortly after power-up. I have one...

There is a data sheet for "26650Fe3300" cells on FullRiver's web site which includes .5C charge and discharge curves. Rated 1000 cycles. Charge .2C CC -> 3.6v -> .05C. Max discharge 1C. (You are at their "max" drawing 23.1A from the 7P packs.) I gambled and bought a few boxes myself as...
