I used my brand battery for 3 charges over 2 weeks. All the wires have been correctly installed/plugged in - and have never ever been installed incorrectly, including the 3S balance wire. I have 2 chargers BC20-4 and both do same thing. What I am seeing is this: It reads 7.3V on my volt meter Charge Status LED is flashing on/off RED. Cell 1 LED is flashing on/off. Cell 2 LED is off. Cell 3 LED is off. I have tried connecting to to my other battery for less then 2 minutes. Any suggestions?
