Kastar 3-Pack NP-FP50/FP51 Battery & LTD2 USB

This set includes three lithium-ion batteries and a dual-slot USB charger. It is designed for owners of compatible Sony Handycam camcorders who need replacement power cells. The kit suits videographers looking for a portable charging solution with multiple battery backups.

Dual USB Charger with Micro-USB and Type-C Inputs

The LTD2 charger accepts 5 V 2‑3 A input through either Micro‑USB or Type‑C ports and can charge two batteries simultaneously. Each slot delivers 8.4 V at 800 mA, and an LCD shows real‑time charging status and capacity. Users without a 5 V 2‑3 A power source will see slower charging rates.

7.4 V 1200 mAh Li‑Ion Cells Rated at 8.88 Wh

Each battery provides 7.4 V and 1200 mAh for an energy rating of 8.88 Wh, matching the original NP‑FP50/FP51 specifications. Shooters requiring higher capacity for extended recording sessions will need larger cells not included in this pack.

Questions about this item

Should I pick the 3-pack or buy a single NP-FP50 battery?

The listing only offers the 3-pack containing three 1200mAh 7.4V batteries and the LTD2 dual charger. Individual cells are not sold on this page.

What does the 8.88 Wh rating mean for recording time on my Handycam?

Each 7.4V 1200mAh cell stores 8.88 Wh. In a DCR-HC85 or similar camcorder this typically yields roughly one hour of continuous recording, depending on LCD use and zoom.

What does the USB-C and Micro-USB input on the LTD2 charger actually limit?

The charger accepts 5V at 2–3A (15W max). Output is capped at 8.4V 800mA per slot, so two batteries charge simultaneously at that rate.
