Ready-to-shoot kit

This pack delivers three 7.4 V 1200 mAh lithium-ion batteries plus an LTD2 dual-slot charger that powers both cells at once. Each cell stores 8.88 Wh and matches the NP-FP51 form factor used by a long list of Sony Handycam models. The charger draws 5 V at up to 3 A through either Micro-USB or USB-C, making it easy to top up from a power bank or wall adapter.

Who benefits and who does not

Videographers carrying compatible Sony camcorders gain a lightweight spare set that fits existing battery compartments and charges from common USB sources. Users whose cameras require a different voltage, a higher capacity, or a proprietary dock will not be served by this kit. Buyers needing more than two simultaneous charge slots should look elsewhere.

The deciding spec

The charger outputs 8.4 V at 800 mA per slot whether one or two batteries are inserted, so recharge time per cell stays constant. If your workflow demands faster turnaround per battery, this charger will not meet that requirement.

Questions about this item

How do I insert the NP-FP51 battery into my Sony DCR-SR50 and what is the common mistake?

Slide the battery onto the camcorder's rear mount until the latch clicks; the frequent error is stopping before the click, leaving the contacts misaligned.

What maintenance will the three NP-FP51 packs and the LTD2 charger need over time?

Keep the charger's Micro-USB and Type-C ports free of dust, wipe battery contacts with a dry cloth if they oxidise, and store packs at roughly half charge when unused for weeks.

Which limit appears first during continuous recording with these 1200 mAh 7.4 V batteries?

The 8.88 Wh capacity typically runs out before the charger's 8.4 V 800 mA output becomes a bottleneck, so runtime ends when the pack is depleted.
