Voltage before charging
|
Status
|
2SxP |
6V or higher |
Good condition |
3SxP |
9V or higher |
Good condition |
4SxP |
12V or higher |
Good condition |
2) Select number of cells or appropriate voltage.
2SxP = 2 cells or select 7.4V |
3SxP = 3 cells or select 11.1V |
4SxP = 4 cells or select 14.8V |
3) Select charge current.
If not listed, limit charge current to 1C!!!
Capacity | Charge current |
730 mAh | 700-750 mAh |
880 mAh | 700-900 mAh |
1200 mAh | 1000-1300 mAh |
1300 mAh | 1000-1300 mAh |
1950 mAh | 1500-2000 mAh |
2050 mAh | 1500-2000 mAh |
2600 mAh | 2000-2600 mAh |
6000 mAh | 2000-6000 mAh |
7800 mAh | 2000-8000 mAh |
8200 mAh | 2000-8000 mAh |
4) Check your charger for safety.a) After charging, check the battery with Voltmeter, the voltage should be:
Cell count | Fully charge voltage |
2 cells pack | 8.32-8.45V |
3 cells pack | 12.48-12.68V |
4 cells pack | 16.64-16.90V |
b) For Triton charger reset timer to 5 hours.
c) Do not use Orbit charger with 6.1 firmware (selecting wrong cell count can cause fire)
d) Let the battery cool down to ambient temperature before charging.
5) Charging batteries in series.a) Battery packs must have the same level of discharge (within 0.1V for 3S4P and 4S4P)
b) Battery pack must be fully charged before use.
6) Storage.a) Never store your battery inside of your car in extreme temperatures.
b) Do not expose battery pack to direct sunlight for extended period.
c) Do not discharge below 3V per cell.
