The Switronix 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.
It is strongly recommended that the first time you charge the battery, it should be charged on the included charger to maximize battery capacity. After the first charge, other chargers can be used as well.
