K&F Concept Ricoh DB-110 / Olympus Li-90B 1100mAh Battery, 2-Pack + 2-Slot Charger

Two Ricoh DB-110 / Olympus Li-90B 1100 mAh batteries and a 2-slot charger with a display that charges them all at once. It runs off Micro USB or USB-C, so a power bank, a laptop or the car will top them up. Fully decoded chip: the camera shows the remaining capacity and raises no third-party battery warning. For Ricoh GR III, GR III HDF, GR IIIx, GR IIIx HDF, WG-6 and Olympus TG-4, TG-5, TG-6, TG-7 (Li-90B and Li-92B batteries).

Two 1100 mAh batteries

The batteries have a capacity of 1100 mAh, that is 4.07 Wh at 3.7 V. In practice that is roughly 2250 shots each. In video one battery lasts around 1 h 45 min (Olympus TG-1).

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.
