SF Tech batteries for heating systems

SF TECH batteries are the key to your thermal comfort during extended dives.

A three-position magnetic switch allows you to precisely adjust the heating intensity directly underwater. The ergonomic shape and positioning of this switch have been specially designed to remain perfectly accessible and easy to use, even with thick dry gloves.

For maximum versatility, the case has a second socket on the top, allowing you to connect your diving light or SF Tech heating system, such as SF Tech heated gloves or SF Tech heating pads, at the same time as your heating system.

Recharging is carried out via this additional connector located on the battery head. This design allows the case to remain closed at all times, eliminating the need to manipulate seals and thus ensuring a perfect long-term watertight seal.

The 23.8 Ah version is particularly popular with technical divers for its ability to maintain constant heat for periods exceeding 7 hours.

🤿 Diveavenue's expert opinion on SF TECH batteries

The 23.8 Ah battery is a real powerhouse. What I like is the consistency of the heating: unlike low-end batteries, the power doesn't drop off after two hours of diving. The canister is compact for such a capacity, which makes it easy to attach to the tank strap or belt without creating any imbalance.
