Replacement Power Kit

This Kastar set supplies a 7.4 V lithium-ion battery rated at 2300 mAh together with a compact dual-slot charger. It is built for owners of Sony Handycam and Cyber-shot models that accept the NP-FM50 form factor, from the DCR-TRV230 through to the DCR-TRV325. The pack delivers a direct replacement for the original Sony power pack without requiring a proprietary AC adapter.

Thermals and Power Draw

The charger operates from any 5 V USB source rated at 2 to 3 A, drawing up to 15 W while feeding each slot 8.4 V at 800 mA. An intelligent LED display shows real-time charging status and remaining capacity for both cells simultaneously. No active cooling is used, so the unit runs silently during typical overnight or on-location top-ups.

Build and Connectivity

The charger body measures five by three by two inches and accepts both Micro-USB and USB-C input cables, with a Micro-USB lead included in the box. Interchangeable plates allow the same dock to service other compatible Sony battery series such as NP-FM30, NP-FM70 or NP-QM91. This flexibility suits videographers who carry multiple legacy camcorders but it does not support newer NP-FZ or NP-FW type packs.

Questions about this item

How do I install the NP-FM50 battery into my DCR-TRV230 and what step do people often miss?

Slide the battery into the compartment until the latch clicks; the step many miss is fully seating the contact side before pressing the latch down.

What maintenance will the LTD2 charger need later and when should I replace the NP-FM50 battery?

Keep the Micro-USB and Type-C ports clean; replace the battery when run time drops well below the 2300 mAh rating after repeated charge cycles.

What limit appears first during sustained charging of two NP-FM50 packs on the LTD2?

The 800 mA per-slot output caps simultaneous charging speed, so two batteries take longer than one.
