Three-Battery Kit for Sony Handycam Owners

This Kastar pack bundles three NP-FM50 lithium-ion cells rated at 17.02 Wh each with a single LTD2 dual-bay charger. It targets videographers who need extended recording time for compatible Sony camcorders such as the DCR-TRV730, DCR-TRV828 or HDR-HC1 without carrying a wall-wart power supply.

USB-Powered Charger Fits in a Gear Bag

The LTD2 charger accepts 5 V 2-3 A input through either Micro-USB or USB-C, so it can run from a power bank, laptop or car adapter. Two independent bays charge a pair of batteries simultaneously at 8.4 V 800 mA each, while an LCD panel shows real-time capacity for both cells.

Steady Output During Long Shoots

Each 2300 mAh cell delivers a consistent 7.4 V through extended recording sessions, avoiding the voltage sag common with aged original packs. The charger’s intelligent circuitry stops current when a battery reaches full capacity, preventing overcharge during multi-day trips where cells are cycled repeatedly.
