What the pack contains

The Kastar kit supplies two NP-FP50/51 compatible lithium-ion batteries and an LTD2 dual-slot USB charger. Each cell delivers 7.4 volts and 1200 milliampere-hours for an energy rating of 8.88 watt-hours. The set targets owners of the listed Sony Handycam and DCR models who need drop-in replacements.

Sustained charging behaviour

The charger accepts 5 volts at 2 to 3 amps through either Micro-USB or USB-C and feeds each slot 8.4 volts at 800 milliamps. Both bays operate simultaneously so two packs reach full charge in one session. An LCD panel reports real-time capacity and status for each battery during the cycle.

Capacity that decides fit

Each replacement cell is rated at 1200 milliampere-hours and 8.88 watt-hours. Buyers whose camcorder demands a higher capacity pack will find these units fall short of that requirement.

Questions about this item

Does the charger get hot or noisy when charging both batteries all day?

The LTD2 charger runs silently with no fan and only mild warmth during dual-battery charging thanks to its 15 W input limit.

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

Any 5 V USB supply that can deliver 2–3 A — such as a phone charger, power bank or laptop port — via Micro-USB or Type-C.

Will these NP-FP51 batteries work in my older Sony DCR-HC85 camcorder?

Yes, the batteries are listed as direct replacements for the NP-FP50/51 used in the DCR-HC85 and many other Handycam models.
