NiMH 8.4V 1600mAh battery
New technologies have been used in the Ni-MH batteries, thanks to which a high performance and high voltages have been achieved. Ni-MH batteries belong to a group of batteries that have a powerful energy density, so at the same volume they have a higher capacity than batteries made using older technologies. The pack made of Ni-MH cells is ideal for use in ASG replicas. An unquestionable advantage of NiMH cells is the fact that they do not have such a memory effect as NiCd batteries, which significantly extends their life. An additional positive feature is the weight to capacity ratio.
