Three-Pack Replacement for Sony NP-FW50

This set supplies three Kastar NP-FW50 lithium-ion batteries, each rated at 7.2 volts and 1650 milliampere-hours. They fit a wide range of Sony Alpha, NEX, SLT and Cyber-shot cameras plus VG-C1EM and VG-C2EM grips, giving photographers multiple spares for long shooting sessions.

Extended Runtime Under Continuous Use

Each cell delivers 11.8 watt-hours, so the combined pack provides substantially more total energy than a single original battery. The chemistry maintains stable voltage during prolonged bursts such as video recording or rapid still sequences, reducing the frequency of battery swaps.

Built-In Protection and Certified Safety

Integrated circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating. The cells comply with UL 1642 and CE standards, so they operate within normal temperature limits during typical camera workloads without requiring extra cooling.

Questions about this item

Does the 7.2 V lithium-ion pack run hot during long shooting sessions?

The cells include over-heating protection and meet UL1642 and CE safety standards, so they stay within safe temperature limits during extended use.

Will these 1650 mAh batteries charge in my Sony BC-VW1 or BC-TRW charger?

Yes, they are direct replacements for Sony NP-FW50 and W Series batteries and work with the BC-VW1 and BC-TRW chargers listed.

Can I mix one of these packs with an older original NP-FW50 in my A6000 grip?

They fit the same VG-C1EM and VG-C2EM grips and the A6000 body, so you can use them alongside an original battery without fit issues.
