Four-pack NP-FW50 for Pixii and Hasselblad

This set contains four Kastar NP-FW50 lithium-ion batteries built for the Pixii A1571, Pixii A2572 and Hasselblad Lunar mirrorless cameras. Each cell delivers 7.2 V and 1650 mAh for a total of 11.8 Wh. Photographers who need several spares for a full day of shooting can swap them without hunting for a charger.

Thermals and safety circuits

Built-in protection guards against over-charge, over-discharge, over-voltage, over-current and over-heating. The cells meet UL1642 and CE safety standards. In normal use the pack runs cool and silent, drawing only the current the camera requests.

Compatibility and daily handling

The batteries slot straight into the listed Pixii and Hasselblad bodies with no adapters required. A four-pack lets you rotate cells through a single charger so one is always ready. Buyers who need a different form factor or a higher capacity than 11.8 Wh should look elsewhere.

Questions about this item

How do I install the Kastar NP-FW50 batteries in my Pixii A1571 and what step is often missed?

Open the battery door, align the contacts, slide each 7.2 V cell in until the latch clicks, then fully charge all four packs before the first shoot.

What maintenance will these Li-Ion 1650 mAh packs need over time?

Recharge at least every three months during storage, avoid letting them sit empty, and swap the set once run-time drops noticeably.

Which limit appears first during continuous shooting with the 11.8 Wh cells?

Heat builds up in the pack and triggers the over-heating protection, pausing output until the temperature falls.
