DESCRIPTION
Underwater battery packs are designed to power various submersible equipment (lighting equipment, underwater acoustic devices, etc.). They are made from high-quality batteries that provide more than 3000 charge-discharge cycles. The batteries and electronics are potted in a durable and wear-resistant polyurethane compound, which provides a high degree of protection not only against the effects of an aggressive environment, but also against vibration. The battery packs turn on automatically when they enter the water and also turn off automatically in air. They require no maintenance other than charging. The packs are equipped with a connector rated for immersion to depths of up to 400 meters.
