Two-battery kit with dual USB charger

This set supplies two 7.2 V lithium-ion cells rated at 1650 mAh each, giving 11.8 Wh per battery. A compact LTD2 charger powers both cells simultaneously from any 5 V USB source. The pack targets photographers using Sony mirrorless bodies such as the a6000 or a6300 who need spare power for day-long shoots.

Cool running and silent charging

Each cell uses standard Li-ion chemistry that generates minimal heat during normal replenishment. The charger draws up to 15 W from a USB port and delivers 8.4 V at 800 mA per slot, so temperatures stay low and no fan is required. An integrated LCD shows real-time capacity and charging status for both batteries at a glance.

Steady output during extended sessions

Under continuous camera use the batteries maintain their rated voltage without sudden drops, supporting long bursts of stills or video recording. The dual-slot design lets one cell charge while the other powers the camera, minimising downtime. Photographers needing more than two cells or a dedicated AC wall adapter will need a different solution.

Questions about this item

How do I charge both NP-FW50 packs using the LTD2's Micro-USB or Type-C input?

Connect the supplied Micro-USB cable to the charger's Micro-USB or Type-C port and a 5 V 2–3 A source; the LCD shows each 7.2 V 1650 mAh cell charging at 800 mA simultaneously.

When will the two 1650 mAh Li-Ion cells need replacing?

Expect 300–500 full cycles before capacity drops below 80 %; store at 40–60 % charge if unused for weeks.

What stops the LTD2 from charging faster than 800 mA per battery during long sessions?

The fixed 8.4 V 800 mA output per slot and 15 W input ceiling limit sustained throughput.
