Three-battery kit with dual-bay USB charger

This kit includes three lithium-ion batteries rated at 7.4 volts and 1200 milliampere-hours each, plus an LTD2 charger that powers two cells simultaneously. It replaces Sony NP-FP50 and NP-FP51 packs and fits a long list of Handycam models from the DCR-DVD, DCR-HC, DCR-SR and HDR-HC series. The bundle suits owners of those camcorders who need spare power for extended shoots. It is not for users whose cameras require a different battery form factor or voltage.

LCD dual charger with Micro-USB and Type-C input

The charger accepts 5 volt input at 2 to 3 amps through either Micro-USB or Type-C ports and delivers 8.4 volts at 800 milliamps per bay. An integrated LCD shows charge status and remaining capacity for each battery. A Micro-USB cable is included in the box. The charger also supports interchangeable plates for other battery types. It does not help photographers who need a mains-powered dock or a single-bay travel charger.

8.88 watt-hour capacity per battery

Each cell stores 8.88 watt-hours, which determines how long a compatible camcorder can record before a swap is needed. The three-pack multiplies that runtime without increasing the charger footprint. Buyers who need higher capacity per cell or a different chemistry should look elsewhere.

Questions about this item

How many charge cycles can the 1200mAh lithium-ion batteries handle before runtime drops noticeably?

The 1200mAh lithium-ion packs are rated for hundreds of charge cycles; keeping them cool and avoiding full discharges extends their useful life.

What limits continuous operation when powering a camcorder from the 7.4V 8.88Wh packs?

The 1200mAh capacity sets the runtime ceiling; under sustained draw the voltage will sag once the 8.88Wh reserve is depleted.

How warm does the LTD2 charger get and how much power does it draw when charging two batteries at 800mA each?

The charger pulls 15W from a 5V 2-3A USB source while delivering 8.4V 800mA per slot; it runs warm but stays within normal operating temperature.
