I put similar question to Rodney Dilkes from EV Power:
"I have 2 Kimberley 120 Ah Series 3 batteries (IFM12-1100E3) manufactured by O'Cell in China and connected in parallel in Kimberley Kruiser S2 (YOM2015). One battery has faulty internal BMS board but all cell in both batteries are OK with 3.4 V across each cell. Is it possible to use the cells from both batteries with your external BMS?"
His answer was:
"Sorry, I don’t think that would work well."

Initially, my batteries failed almost simultaneously due to mechanical failure of Chinese made ZOMKUN (ZK02-120, col: 9VDC) latching relays inside the battery box. These could not be sourced locally nor from China. I replaced them with locally sourced OMRON (G9TB-U1ATH-E, col:12VDC) latching relays. Everything worked fine until I accidentally shorted the BMS board in one of the batteries.
Failure of $5 relays disabled originally AU$2550 (each) batteries. It is hard to understand why the battery boxes were glued shut when they contained serviceable parts. I note that several brands of LiFePO4 batteries are now fully serviceable (–eg. Enerdrive ePower B-Tec G2, Safiery).
Anyhow, I am still trying to source a dead or alive Kimberley 120AH Series 3 battery which has a functional BMS.
Cheers, Zed
