This NiMh battery with 300 mAh serves as a replacement power supply for Car-System vehicles. Thanks to its compact dimensions, the NI300 fits perfectly in buses, trucks, and other vehicles with larger interiors. The individual terminals of the battery can be easily soldered to achieve the required system voltage of 2.4 V through series connection if necessary (System voltage 1.2 V = 1 x NI300, System voltage 2.4 V = 2 x NI300 in series). The batteries can be charged using the existing Car-System charger.
