The Core SWX Bolt Battery Kit consists of a 7.2V lithium-ion battery and a travel charger.
Designed specifically for the TL-BT200 LED light, the battery has a 6600mAh capacity and will power your light for up to 2 hours (a bit less at max light output). Equipped also with a Sony InfoLithium microchip, the battery can be used to power Sony camcorders that accept L-Series batteries.
The charger works with any outlet rated between 110-220 VAC. It features an LED indicator that lights red when charging and that changes to green when finished charging.
