Voltages in the table above are for a single cell.
The max. charge and discharge currents are expressed with the capacity value “C”.
A charging current of 1C corresponds to the capacity value printed on the battery (e.g. given battery capacity
1000 mAh, max. charging current 1000 mA = 1 A).
Always observe the correct voltage setting for battery packs with multiple cells. The individual cells of a
two-cell battery pack, for instance, can be connected both in parallel and in series.
Exceeding the battery’s maximum allowable charging current or selecting the wrong number of cells/
voltage settings carries the risk of ruining the battery. The battery also poses explosion and fire hazards!
For more information about the max. charging current and the number of cells/voltage, see the data
sheets or the label of the battery; those data have priority over the information given in the table above.
Important!
• Never charge battery packs that consist of different cells (or of cells from different manufacturers).
• Never attempt to charge non-rechargeable batteries.
• Never charge batteries that are not listed in the table above.
• Never charge batteries with integrated electronics.
• Never charge batteries that are still connected with other devices (e.g. a speed controller).
• Never charge damaged or swollen batteries.
