Three-battery kit with dual-slot USB charger

This pack supplies three 1900mAh lithium-ion cells and a compact charger that accepts two batteries at once. Each cell stores 7.3 Wh at 3.85 V. The charger shows charge level and status on an integrated LCD panel. Micro-USB and USB-C inputs let you power it from common adapters or power banks. The bundle suits owners of HERO 9, 10 or 11 Black cameras who want spare capacity for long shoots.

Check camera model and charger plates before

The batteries replace GoPro ADDBD-001, ADBAT-001 and ADDBD-211 cells used in HERO 9, 10 and 11 Black editions. Verify that your camera matches one of those models. The charger includes swappable plates; confirm the correct plate is fitted for the GoPro cell type. A 5 V source capable of 2 A to 3 A is required for the 15 W input rating. The box includes a Micro-USB cable but no wall adapter.

Steady output during extended charging sessions

Each slot delivers a constant 4.2 V at 800 mA whether one or two cells are inserted. The LCD updates in real time so you can monitor progress without guesswork. Thermal regulation prevents the charger from throttling when both bays run continuously. The 7.3 Wh cells maintain usable voltage through repeated cycles, supporting multi-day trips without access to mains power.

Questions about this item

Does the Kastar pack include everything needed to charge three batteries, or must I buy extra cables or plates?

The set contains one LTD2 dual-slot charger, three 1900 mAh Li-Ion batteries and a Micro-USB cable. The charger accepts Micro-USB or Type-C input so you can use any 5 V 2–3 A power source you already own. No extra plates or cables are required for the three included batteries.

Should I choose the 7.3 Wh Kastar cells or look for a higher-capacity version for my HERO 11 Black?

Each Kastar cell is rated at 3.85 V, 1900 mAh and 7.3 Wh, matching the GoPro ADDBD-211 specification for HERO 9, 10 and 11 Black. If you need longer run-time per battery you would need a higher-capacity model, but these deliver the same capacity as the original GoPro packs.

What does the 800 mA output current mean for actual charge time when I put two batteries in the LTD2 charger?

The charger supplies 800 mA per slot whether one or two batteries are inserted. At that rate a depleted 1900 mAh cell takes roughly two and a half hours to reach full charge, so both batteries finish in the same time when charged together.
