Kastar LI-50B Battery Kit

This Kastar kit supplies two lithium-ion replacement batteries and a quadruple USB charger for Olympus Li-50B, Panasonic VW-VBX090 and Pentax D-Li92 cameras. Each cell delivers 3.7 V and 1800 mAh capacity, rated at 6.66 Wh. The bundle suits photographers who need spare power for long shooting days with compatible tough or compact models.

Charger Power and Thermals

The compact charger accepts 5 V at 2 to 3 A through Micro-USB or Type-C inputs, drawing up to 15 W. It outputs 4.2 V at 800 mA when charging one or two batteries, dropping to 500 mA per slot with three or four cells inserted. An intelligent display shows real-time charging status and remaining capacity for each bay.

Interchangeable Plates and Cable

Swappable charging plates let the single unit handle different battery form factors without extra adapters. A Type-C cable is included so the charger works with modern power banks or wall adapters immediately. Users relying on proprietary AC docks or needing simultaneous charging beyond four cells will require additional equipment.

Questions about this item

How do I install the two Kastar batteries into the quadruple charger, and which step do people get wrong?

Insert each battery into the interchangeable plate with the contacts aligned, then plug the Type-C or Micro-USB cable into a 5 V 2–3 A source; the common mistake is skipping the plate swap when moving between Olympus Li-50B, Panasonic VW-VBX090 and Pentax D-Li92 packs.

What maintenance will the two 1800 mAh Li-Ion packs need later?

Store them at roughly half charge in a cool place, recharge every few months to avoid deep discharge, and keep the charger’s contact pins clean so the intelligent display reads capacity correctly.

What limit appears first when charging four batteries at once for long periods?

The charger drops to 500 mA per slot with three or four cells, so total charge time lengthens and the 4.2 V 800 mA peak is only available when one or two batteries are fitted.
