Dual 6v Battery Tray for 07-18 Mercedes Sprinter Vans. This battery tray can accommodate 2, GC2 group size batteries. Wire the two 6-volt batteries in series to get your 12 volts and now you have 220+ Ah capacity where you had either none before or 110 Ah with the factory battery. #rbcomponents #rbadventurevans #sprintervanconversion #campervan #diyvan
