Kastar GOPRO12 battery and LTD2 charger kit

This kit supplies a 7.3 Wh lithium-ion cell rated at 1900 mAh and 3.85 V alongside a dual-slot USB charger. It targets owners of GoPro HERO 9, 10, 11 or 12 Black cameras who need a spare power source and a way to recharge two batteries from any 5 V 2–3 A USB supply.

Sustained charging behaviour

The charger delivers 4.2 V at 800 mA per slot whether one or two cells are inserted, so total output remains 15 W from the 5 V input. An integrated LCD shows real-time capacity for each bay, letting you monitor progress during extended shooting sessions without guessing remaining charge.

Installation notes and common issues

Insert each battery into its dedicated plate; the charger accepts Micro-USB or USB-C input and includes a Micro-USB cable. The only frequent problem is attempting to charge cells from incompatible camera generations, which the plate mechanism prevents by physical keying.

Questions about this item

Does the LTD2 charger get hot or noisy when both battery slots run all day?

The charger draws up to 15 W from a 5 V 2–3 A USB source and outputs 4.2 V at 800 mA per slot, so heat stays low and there is no fan to make noise.

What power source do I already need to run the LTD2 charger?

Any 5 V USB supply rated at 2–3 A — such as a phone brick, laptop port or power bank — using the included Micro-USB cable or a Type-C cable you provide.

Will the 1900 mAh Kastar battery work in my HERO9 Black alongside the original GoPro cells?

Yes, the 3.85 V 7.3 Wh Li-Ion pack is listed for HERO9, HERO10, HERO11 and HERO12, so it mixes freely with OEM ADDBD-001 or ADBAT-001 batteries.
