It seems most of the discussions here are about the quality of the cell/chemistry. A lot of times the cells didn't fail, it's the BMS/protective circuit board failed, which isn't doing its job and allowed individual cell draining itself. Say when a 2S1P 7.2V Li-Ion battery, a cell drops to <2V, the circuit board may simply cut off the circuit and the charger would return an error on the battery. But I guess what I've just said didn't contribute much to the thread, buy what you want.
