The 9.6v 1500mah battery pack is designed to fit into weapons such as the ECHO1/Kart EBR that normally only have space for a conventional mini battery. The battery fits in the ECHO1/Kart EBR hand guard by splitting the battery pack into two halves that go on opposite sides of the barrel.
Nickel-cadmium batteries must be discharged before they are recharged, failure to do so will result in damaged battery cells.
