Underwater battery packs |
Underwater battery assemblies are designed to power various submersible equipment (lighting equipment, hydroacoustic devices, etc.). They are made on the basis of high-quality batteries that provide more than 3000 charge-discharge cycles. Batteries and electronics are poured into a durable and wear-resistant polyurethane compound, which provides a high degree of protection not only from the effects of an aggressive environment, but also from vibrations. Battery assemblies turn on automatically when they enter the water and also automatically turn off when exposed to air. Do not require any maintenance other than charging. The assemblies are equipped with a connector designed for diving to depths of up to 400 meters.
