Designed for consistent heating performance, this battery maintains a stable output voltage, ensuring steady temperature throughout the entire dive, unlike most other heating batteries on the market. Divers can select between two constant voltage levels based on their heating needs: ~11V for standard heating (similar to typical dive batteries) ~12V for additional heating power. The difference is really noticeable and will be greatly appreciated on ling, cold dives! Key Features: Ergonomic E/O cord connector with dual LED indicators Visual and audible alerts for operating mode and low battery Anti-slip housing design for surface handling User-replaceable E/O cord—no service visit required Durable piezoelectric power button for reliable activation Engineered for performance, safety, and convenience—whether you’re diving in temperate waters or pushing the limits in extreme cold. The large 28 ah battery may be mounted upside down on the back of a CCR, giving the diver access to the power switch while maintaining a streamlined profile.
