Kastar GOPRO12 two-battery kit

This set supplies two 1900mAh lithium-ion cells rated at 3.85V and 7.3Wh each, plus an LTD2 dual-bay charger. It targets owners of HERO9 through HERO12 Black action cameras who need spare power for extended shoots.

Charger sustains 800mA per bay

The LTD2 delivers a steady 4.2V at 800mA whether one or two batteries are inserted, so the second cell does not slow the first. A 15W input keeps that rate stable during back-to-back cycles.

Micro-USB and Type-C inputs only

The charger accepts 5V at 2-3A through either port, limiting total output to 15W. Cameras that demand higher charge voltages or proprietary handshakes cannot be powered from this unit.

Questions about this item

Does the LTD2 charger get hot or draw much power when it runs all day?

The charger input is 5V 2-3A up to 15W and each output is 4.2V 800mA, so it stays cool and uses little power during extended charging.

What power source do I need to run the charger?

Any 5V USB supply rated at 2-3A works, and the box includes a Micro-USB cable for Micro-USB or Type-C input.

Will these batteries fit my HERO9 Black?

Yes, the 1900mAh 3.85V Li-Ion cells are listed as compatible with HERO9, HERO10, HERO11 and HERO12 Black models.
