Four batteries and dual charger for Ricoh cameras

The pack contains four Li-90B lithium-ion cells and an LTD2 charger that powers two batteries at once. Each cell stores 4.81 Wh at 3.7 V and 1300 mAh. The set replaces the Ricoh DB-110 and fits the Ricoh GR III, GR IIIx, WG-6, G900 and the THETA V, Z1, X and earlier 360 models. It is built for photographers who need spare power on long shoots.

USB charger runs cool

The LTD2 unit accepts 5 V at 2 to 3 A through Micro-USB or Type-C and delivers 4.2 V at 800 mA per slot. An LCD panel shows real-time capacity and charging status for both bays. No fan is fitted, so operation stays silent while the charger manages current to keep temperatures low during typical use.

Swappable plates and compact build suit travel

The charger measures 5 by 3 by 3 inches and uses interchangeable plates to accommodate different battery types. A Micro-USB cable is included for immediate connection to power banks or wall adapters. The lightweight construction slips into a camera bag without adding bulk, and the dual-slot layout lets you top up a pair of cells while you keep shooting.

Questions about this item

How do I insert the four Li-90B packs into the LTD2 and which orientation do people get wrong?

Slide each pack into one of the two bays with the contacts facing the board; the charger only accepts two at a time so the other two must wait for the first pair to finish.

What part of this kit will wear out first and need replacing?

The 1300 mAh lithium-ion cells lose capacity over repeated cycles; the charger itself has no moving parts and rarely fails.

At what point does the LTD2 charger throttle during a long charging session?

When the two bays draw 800 mA each the 5 V 2–3 A input reaches its limit and the LCD shows a slower charge rate.
