P • Using the D400 Charger with a RangePro RPX8-P Battery
The Charger Will Only Charge the Battery at 0.1A and it Takes a Long Time
1.
This can happen when a battery is significantly drained beyond normal operating voltages and the cell
voltages have fallen below a certain charging threshold.
2.
When using the LiHV model as a basis for a customized program, if the total battery voltage is below 20.4
volts (3.4 volts per cell), the charger will only trickle charge at 0.1A until the battery reaches the minimum
voltage threshold. After all cells exceed the minimum voltage threshold the unit will switch to charging at
full current until the process nears completion. Near the end of the charging process the current will slowly
decrease as the individual cells are finely balanced.
3.
One way to accelerate the charging process when slow charging occurs is to start charging in the LiPO
mode, being sure to set the channel to 6Amps and a 6S configuration, which has a lower charging thresh-
old of 19.8 (3.3 volts per cell). After the battery voltage exceeds 20.4 volts per cell switch to the customized
LiHV model to obtain a full charge of 4.30 volts per cell.
