BD380 is a powerful discharging device that allows the user to discharge a battery at up to 40 amps or 380 watts and also measures and compares the battery performance. BD380 allows for the precise measurement of battery capacity and takes the guesswork out of choosing the best battery for your application.
BD380 is much more than a simple battery discharger or a battery load tester. It will test virtually any type or size of battery, any chemistry or number of cells, up to 30 volts.
BD380 is ruggedly built and uses XT60 connector for battery connection. It is small with a high-performance cooling system. The display indicates battery voltage, discharged capacity and discharge current.
BD380 has four operating modes, and each operating mode has distinct use cases:
Constant Current (CC) Mode: In this mode, the BD380 maintains a constant current output regardless of changes in resistance or voltage. This mode emphasizes the constant current flow for predictable energy depletion, ideal for precise capacity testing and battery health assessment.
Constant Resistance (CR) Mode: In CR mode, the BD380 maintains a constant resistance load, simulating devices with fixed resistance characteristics. This mode is useful for capturing the simulation of a constant resistive load, offering a realistic scenario for evaluating energy storage under consistent conditions.
Constant Power (CP) Mode: CP mode allows the BD380 to deliver a constant power output irrespective of variations in voltage or current. It is beneficial for reflecting the ability to maintain constant power output, adapting to the needs of diverse applications requiring steady power delivery.
Constant Voltage (CV) Mode: In CV mode, the BD380 provides a stable voltage output despite changes in current or resistance. This mode is commonly used to highlight the maintenance of a constant voltage level, ensuring devices operate within their optimal range while adapting current flow.
Charge Master – computer Control:
BD380 can work in conjunction with SKYRC’s T100o and D200neo chargers. When working together, they support computer connection and control. If the “Charge Master” computer software is also being used, the BD350 becomes a powerful measuring instrument, as it allows the exact measurement of battery capacity and performance. You can view the battery’s discharge curve in real time and then plot them against each for precise comparison and analysis. In this way, the best batteries can be identified quickly and defective batteries have nowhere to hide. Please visit SkyRC’s official website to download the CHARGE MASTER software.
BD380 is also equipped with a built-in Bluetooth module, allowing it to be connected and controlled using a mobile phone. You can easily achieve this by downloading the app “SkyCharger”, which is available for free on Google Play and the App Store.
