The BD380 is a powerful discharging device, enabling the user to discharge a battery at up to 40 amps or 380 watts. It also enables battery performance to be measured and compared. The BD380 enables precise measurement of battery capacity, so there's no need to worry about which battery is best suited to your application.
The BD380 is much more than just a battery discharger or under-charge tester. It will test virtually any type or size of battery, whatever its chemistry or number of cells, at voltages up to 30 Volts.
The BD380 has a robust construction and uses an XT60 connector for battery connection.
It's a compact system, but with a high-performance cooling system. The display shows battery voltage, discharged capacity and discharge current.
Key features
- Displays battery voltage, discharged capacity and discharge current in real time.
- Allows battery capacity to be tested, helping to select batteries of the desired capacity.
- Saves time when putting high-capacity batteries into storage.
- Helps to activate your batteries' best performance for competition.
- Supports free Android and iOS apps for download
- Detects the quality of stabilized DC power supplies.
