User Manual
Charger support resistance detection. This function can only be used while charger is doing
balancing charging. After initiating charging task in 2~3 minutes, charger can measure cell
resistance. In dierent battery capacity, battery resistance is dierent. Generally speaking, higher
the remaining capacity is, resistance is lower.
During resistance measurement, charger will adjust instantaneous current. So during charging if
you nd any sudden change of current, this is normal.
This value of resistance is not as precise as professional resistance meter. Resistance is only used
for comparison for each cell. Also charging current inuence resistance accuracy.

Over-discharging battery reactivate and repair function
After charging task initiates, if battery voltage is lower than pre-charging voltage, charger will
charge battery at 0.1A to reactivate and repair. After battery voltage is higher than pre-charging
voltage, charger will charge battery as setting. This procedure can protect over-discharging
battery then reactivate and repair
Over-discharging battery reactivate and repair function
During charing process, screen displays orange, after charging completion screen will change to
green or blue. After charging completion, voltage dierence between each cell is less than
20mV, screen will turn to green. If you are in hurry, it's good to stop the charging process. If keep
charging, charger will continue balancing battery, if voltage dierence is less than 10mV, screen
will turn to blue. After that, charger will continue to precise balancing battery. If dierence is
small enough, after charging completion, charger jump to blue directly.
Due to the performance of dierent kinds of battery, after charging completion, voltage will fall
a little. This is normal. For battery used for a lot of times, this will occur more often. Charging with
higher current this circumstance would occur too.
Kind notice: For eld charging, if you would like to do quick charging, when screen shows green
it's ok to stop charging. If you would like to do precise charging, wait until blue.
Charging process complete.
