Cameron & Co DS-CS-PLS100MX Camera Battery

This 3400mAh lithium-ion battery powers Panasonic Lumix DC-S1, DC-S1R, S1 and S1R cameras. It replaces the original DMW-BLJ31 and DMW-BLJ31E packs with a 7.4V 25.16Wh capacity. The black cell measures 72.56 x 41.60 x 21.26 mm and is supplied as a single unit.

For Lumix S-Series Owners Needing a Spare

Photographers who want a reliable backup for long shoots or travel will find this a direct fit. Videographers requiring continuous power for extended recording sessions should check the camera's own power-handling limits, as this pack does not add features such as USB charging or higher voltage output.

3400mAh Capacity at 7.4V

The 25.16 watt-hour rating determines how many stills or minutes of video you can capture per charge. If your workflow demands more energy than this single cell provides, you will need additional batteries or an external power solution.

Questions about this item

How much heat or power draw should I expect from the 7.4 V 3400 mAh Li-ion cell during all-day shooting?

The battery stores 25.16 Wh at 7.4 V and 3.4 Ah, so continuous power draw depends entirely on the camera's consumption; the cell itself generates minimal heat under normal load.

What must I already own for this DS-CS-PLS100MX pack to work in my kit?

You need a Panasonic Lumix DC-S1, DC-S1R, S1 or S1R body that accepts a DMW-BLJ31 or DMW-BLJ31E battery, plus a compatible charger for 7.4 V Li-ion cells.

Will this 72.56 × 41.60 × 21.26 mm battery fit and communicate properly in an older Lumix S1 body I plan to keep?

Yes — it matches the DMW-BLJ31/E form factor and 7.4 V 3400 mAh specification, so it seats securely and reports capacity correctly in both S1 and S1R models.
