The BD380 is a powerful discharger that allows you to discharge a battery with up to 40 amps or 380 watts in a relaxed manner. But that's not all, because the discharger also offers the option of measuring the battery performance during the process and even comparing it with other batteries. And a precise measurement of the capacity helps immensely when choosing the best battery for your next ride. No matter what kind of battery you want to discharge, factors and distinguishing features such as type, size, chemistry and the number of cells are irrelevant. At up to 30 volts, the BD380 can handle a wide variety of different batteries. The robust housing with XT60 connection for the battery also conceals an effective cooling system to ensure an optimum operating temperature. The large colour display shows values such as the battery voltage, the discharged capacity and the discharge current.
