Four-pack lithium-ion kit

This Kastar GMB1865 set supplies four 3.7 V 2600 mAh lithium-ion cells plus a matching AC wall charger. It targets photographers, videographers and outdoor users who rely on Manfrotto MVG460 or MVG460FFR gimbals, EVO GP, GP-PRO, RAGE3 or Gen 1 RAGE gimbals, Moza Air 2 or Feiyu AK series stabilisers, XHDATA D-808 radios, Blink cameras, headlamps, torches, doorbells or RC vehicles. The 9.36 Wh capacity per cell keeps compatible gear running during extended shoots or trips.

Compact charger with foldable plug

The included charger accepts 100–240 V AC at 50 or 60 Hz and delivers 4.2 V at 600 mA through a foldable flat pin that stores neatly in a bag. A red LED shows active charging while a green LED signals standby or full charge, giving clear status at a glance. The 3 × 2 × 3 inch footprint fits tight outlets and travel pouches without blocking adjacent sockets.

Replaces single OEM cells

Users swapping out a lone GMB-B117 or GMB-B118 battery gain three spares and a dedicated charger, eliminating the wait for a single cell to recharge. The jump makes sense when a gimbal, camera or light drains one pack per session and downtime costs shots. Buyers needing higher-capacity cells or a multi-bay charger for simultaneous charging should look elsewhere.

Questions about this item

What input voltage range does the AC wall charger accept?

The charger accepts AC 100–240 V at 50–60 Hz, so it works on mains supplies worldwide without a voltage converter.

What are the physical dimensions of each battery?

Each cell measures 3 × 2 × 3 inches, a compact brick shape that fits the listed gimbals, cameras and torches.

How do you insert the batteries into the charger, and what mistake should be avoided?

Slide each battery in with the correct polarity; forcing it backwards is the common error that prevents charging and risks damage.
