Battery precisely fitting for the Gudereit EC4, EC-4 E-Bike Series. A replacement or secondary battery from E-Bike-Vision for the Bosch E-Bike battery Powerpack 500 in anthracite for frame mounting on Active Line, Performance Line, and Performance Line CX. This replacement battery is manufactured in Germany, but it is not an original Bosch battery. A freshly manufactured E-Bike battery in Germany compatible with the Bosch Powerpack 500 and the battery part number P/N 0275007530 Bosch battery. It is a Li-Ion frame battery with a capacity of 10 Ah. This can be used with Bosch E-Bike drives from the Active Line, Performance Line, and Performance Line CX. Thanks to the use of the currently extra strong 21700 Li-Ion batteries Samsung INR21700-50E, the battery can be charged or recharged at any time, as the Li-Ion system does not have a memory effect. Due to the very low self-discharge of the 21700 batteries inside the battery pack, long storage periods, such as over the winter months, are not a problem. The intelligent Battery Management System (BMS) developed by BE-Bike-Vision protects the high-quality battery from overcharging, overheating, overload, and deep discharges. A current 2020 BMS continuously checks each individual 21700 battery to optimize the lifespan of the entire battery power pack. The Lite batteries for the luggage rack have 360 Wh. By using Samsung's 21700 cell technology, the weight has been reduced to just 2000 grams. This significant weight saving allows for a range comparable to a 500 Wh battery, meaning that due to the weight reduction, this battery can also replace the 300 Wh, 400 Wh, and 500 Wh batteries.
