Two 2600 mAh batteries

The batteries have a capacity of 2600 mAh, that is 18.72 Wh at 7.2 V. In practice that is roughly 705 shots each, about 1410 for the whole set. In video one battery lasts around 4 h.

2-slot charger

The charger has 2 slots and is powered over Micro USB or USB-C, so a power bank, a laptop or a car charger will do. The display shows the state of each battery separately.

The chip watches over-charge, over-discharge, over-voltage, over-current, short circuit and overheating, and switches to trickle charging once full.
