Kastar LI-90B 2-pack battery and LCD triple USB charger

Two-pack LI-90B batteries for Olympus cameras

This set supplies two 1300 mAh lithium-ion cells rated at 3.7 V and 4.81 Wh each. They replace the Olympus LI-90B and LI-92B packs used in a long list of Stylus and Tough models from the SH series to the TG-7. Photographers who carry a compatible Olympus camera gain a ready spare for extended shooting days.

LCD triple charger powered by any 5 V USB source

The included charger accepts a 5 V 2 A input through a micro-USB cable and can charge three batteries simultaneously at 4.2 V 0.5 A per slot. An intelligent LCD panel shows real-time charging status and remaining capacity for each cell. Power comes from a wall adapter, car charger or computer, so no dedicated AC brick is required.

Steady 0.5 A per slot keeps cells cool during long

Each bay delivers a constant 0.5 A charge current rather than a rapid burst, which reduces heat build-up when all three positions are occupied. The LCD lets you monitor progress without guessing, and the charger stops automatically when each battery reaches full capacity. This behaviour suits overnight top-ups or multi-battery rotation in the field.
