Battery for Torpedo
The Torpedo battery is noted for high-rate capability and high energy density because of its high electrochemical energy, the optimized design and using the excellent properties of the materials.
The combat battery consists of the battery cell block and activation system. it is activated within a few seconds by a fire signal, and can be used immediately. The exercise battery is possible to charge and discharge within the specified life cycles.
