Two-pack NP-FF50 batteries with dual USB charger

This set includes two lithium-ion batteries rated at 7.2V and 900mAh each, plus an LTD2 charger that powers both simultaneously. The kit supports Sony NP-FF50, NP-FF51 and NP-FF51S cells and fits a long list of Handycam models from the DCR-PC and DCR-IP series.

Thermals, noise and power draw

The charger accepts 5V at 2–3A through Micro-USB or Type-C ports and delivers 4.2V at 800mA per bay. An intelligent LED display shows real-time charging status and remaining capacity for each battery. No moving parts mean silent operation and negligible heat during normal use.

Deciding specification — 6.48 Wh per cell

Each pack stores 6.48 Wh, which determines how long a compatible camcorder can record on a single charge. Buyers who need longer runtimes or higher-capacity cells such as the NP-FF70 series will find this capacity insufficient.

Questions about this item

How do I install the NP-FF50 batteries and LTD2 charger, and what step is often missed?

Insert each 7.2 V 900 mAh battery into the dual charger slots, connect the Micro-USB or Type-C cable to a 5 V 2-3 A power source, and select the correct plate for NP-FF50/51/51S so the LCD shows both cells charging at 800 mA each.

What maintenance or replacement will the NP-FF50 batteries and LTD2 charger need later?

Replace the two Li-Ion batteries when they no longer hold a full 6.48 Wh charge; keep the charger's Micro-USB and Type-C ports clean and verify the LCD still reports 4.2 V output per slot.

What limit appears first during sustained use of the NP-FF50 batteries with the LTD2 charger?

Each battery delivers 900 mAh at 7.2 V, so continuous recording drains the 6.48 Wh capacity before the charger's 800 mA per channel output can replenish it.
