Four-battery kit for Sony Handycam owners

This Kastar kit supplies four NP-FP51 lithium-ion batteries and an LTD2 dual-slot charger. Each cell stores 1200 mAh at 7.4 V, giving 8.88 Wh per unit. The package targets videographers who need extended run-time for compatible Sony camcorders such as the DCR-SR50, DCR-SR60 or HDR-HC3.

Charger limited to 5 V USB sources

The LTD2 charger draws power from a 5 V 2–3 A USB supply through either Micro-USB or USB-C ports. It can charge two batteries simultaneously at 8.4 V 800 mA each, but single-bay output is also 800 mA so total current does not increase. An LCD panel shows charge level and status for each bay.

1200 mAh capacity per cell

Every NP-FP51 in the set delivers 1200 mAh at 7.4 V. This figure determines how long a camcorder can record before a swap is needed. Users who require higher capacity per battery will need a different cell.

Questions about this item

Should I choose the 4-battery pack or a smaller bundle?

This listing only includes the 4-pack with one dual-slot charger; no smaller bundles are offered.

What does the 1200 mAh rating mean for actual recording time?

Each 7.4 V 1200 mAh battery stores 8.88 Wh, which typically powers a compatible Sony camcorder for roughly one to two hours of continuous recording.

How does the USB-C and Micro-USB input affect charging speed?

The charger accepts 5 V at 2–3 A (15 W) via either port and delivers 8.4 V at 800 mA per slot, so two batteries charge simultaneously in about the same time as one.
