1. Correct connection
Cell low voltage: Flashing Red
2. Fault description
(1) The +/- port of battery and balance port
should be all connected to B4 charger well, If connected incompletely,
the B4 charger won’t get into charging state.
(2) If the indicator light is red and
blinks, please check if the balance port is connected completely, and
check if the functions of cell which correspond to this indicator is
good. (Please Note: when the indicator blinks red, this state must be
reset by cutting off power, so when the indicator blinks red, firstly
please check whether the corresponding cell is normal and the balance
port is connected well, if both of them have no problem. Then go to cut
off power for a while, and turn on power to recharge.
(3) If the +/-ports are connected conversely, B4 charger won’t get into charging state either.
