Two-pack Li-ion replacement for Lumix cameras

The Kastar DMW-BLK22 twin pack supplies two 7.2 V lithium-ion cells rated at 2200 mAh and 15.8 Wh each. They are built as direct replacements for the Panasonic DMW-BLK22 battery used in the Lumix GH5 II, GH6, S5 II and S5 IIX mirrorless bodies.

Sustained shooting with built-in protection

Each cell includes over-charge, over-discharge, over-voltage, over-current and over-heating circuits tested to UL 1642 and CE standards. The protection logic maintains stable output during long video takes or burst sequences without tripping prematurely.

Replaces single OEM packs for extended sessions

Swapping a lone original battery for this pair doubles the available capacity for all-day events or travel. The upgrade makes sense when a single charge cannot cover the shoot and carrying a charger is impractical.

Questions about this item

How hot does the DMW-BLK22 get when the camera records video all day?

The Li-ion cells include over-heating protection that cuts power if temperature exceeds safe limits, so the pack stays within normal operating range during extended shoots.

Which charger do I need to recharge these 7.2 V 2200 mAh packs?

They are designed for the Panasonic DMW-BTC15 charger; plug the batteries into that unit for correct voltage and current.

Will the 15.8 Wh capacity work in my older Lumix DC-S5 body?

Yes, the DMW-BLK22 is listed as compatible with the Lumix DC-S5 and DC-S5KK, delivering the same voltage and capacity as the original pack.
