Three-battery kit for Sony cameras

The Kastar NP-FZ100 kit supplies three 7.2 V 2280 mAh lithium-ion cells and a dual-slot LTD2 charger. It replaces the Sony NP-FZ100 battery and BC-QZ1 charger for Alpha and FX series bodies. Photographers and videographers who need multiple spares for long shooting days can carry all three cells in one package.

Sustained shooting performance

Each cell stores 16.4 Wh and delivers 7.2 V through the camera's native power path. The charger outputs 8.4 V at 800 mA per slot whether one or two batteries are inserted, so a full cycle takes the same time per cell. Swapping charged units keeps the camera running without waiting for a single battery to recover.

Thermals and power draw

The LTD2 charger accepts 5 V at 2–3 A through Micro-USB or USB-C, drawing a maximum of 15 W from any standard USB power source. Its LCD panel shows real-time capacity and status for both slots while the unit remains cool to the touch. No fan is fitted, so operation stays silent during overnight charging sessions.

Questions about this item

How warm does the LTD2 charger get when it runs all day charging two NP-FZ100 batteries?

The charger outputs 8.4 V at 800 mA per slot, so total power draw stays around 15 W; it runs cool enough to leave on a desk continuously.

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

You need any 5 V USB supply rated at 2 – 3 A (15 W) — either Micro-USB or USB-C — plus the included Micro-USB cable.

Will these batteries work in my Sony A7 III and A7R IV bodies without firmware issues?

Yes, the NP-FZ100 cells are listed as compatible with the A7 III, A7R IV, A7R V, A1, FX3 and other models that use the original NP-FZ100.
