The CK30 battery pack uses two Li-Ion 18650 cells with a capacity of 
2200mAh. The cells are arranged in series for a nominal voltage of 7.23 
VDC and charging voltage of 8.4V.

The CK30 itself contains no battery charging circuit. Instead, the charging 
circuitry resides in the charging accessory–the AC1 4-bay charger, or the 
AD1, AD2, or AC2 dock. The battery may be charged either by itself (in 
an AC1) or while installed in a CK30 (in an AD1, AD2, or AC2 dock).
