Bosch Battery Extension for Powertube 500wh to 625wh Brand_Voile *Complete waterproof lineBosch powertube batteries come in various physical sizes. Generally speaking, the larger the battery capacity, the longer the powertube battery is physically. This part extends the physical length of a 500Wh powertube battery to make it as long as a 625Wh power tube battery.
