Overview

The Westcott FJ200 Lithium Polymer Battery is a purpose-built replacement power source for the Westcott FJ200 strobe, designed to keep photographers shooting on location without interruption. With a 2500mAh capacity at 14.4V (36Wh), it delivers over 450 full-power flashes per charge — enough for most portrait, event, or commercial sessions. When the battery runs down, a full recharge takes approximately 2 hours, enabling a fast turnaround between shoots or a midday top-up during longer production days.

Weighing just 0.5 lbs, this battery adds minimal weight to a gear bag, making it practical to carry one or two spares for extended work away from power outlets. The lithium polymer cells are rated for over 300 charge cycles, providing a long service life with proper care. The battery slots directly into the FJ200's battery compartment with no adapters required, maintaining the strobe's compact and portable form factor that makes it popular for off-camera flash work.
