DeepSea Power and Light SeaSource:

Features: Small Size Rugged, Durable Design 150-Foot Depth Rating Non-Metallic Housing

The SeaSource is a compact underwater battery pack designed for diver operation. The SeaSource consists of a 12 volt, 6.5 amp-hour "absorbed electrolyte" lead-acid battery packaged in a rugged neoprene boot and covered with a Cordura holster. The glove-like fit of the rubber boot enables the SeaSource to have the smallest possible housing. The rubber pressure relieving housing eliminates the possibility of explosive failures. Incorporated into the clear top of the SeaSource are an on/off switch, charging port, charge status indicator lights, and a fuse inspection area. A Superconn bulkhead connector provides reliable electrical connections that are underwater pluggable. Strap mounting to a camera or other housing is made easy by using two nylon loops on the holster.

The SeaSource coupled with one of DeepSea's underwater lights makes a totally portable underwater/harsh environment lighting system.
