BATTERY DISCHARGER & ANALYZER
FEATURES
It displays real time battery voltage, discharged capacity and discharge current.
It can test battery capacity that helps select batteries with desired capacity.
It saves time when user wishes to store their large capacity batteries.
It helps activate the best performance of your batteries for competition.
Thank you for choosing the SkyRC Battery Discharger & Analyzer (BD250). The BD250 is a powerful
discharging device that allows the user to discharge a battery at up to 35 amps or 250 watts and also
measures and compares the performance of batteries. BD250 allows for the precise measurement of battery
capacity and takes the guesswork out of choosing the best battery for your application.
The BD250 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 35 volts.
The BD250 is ruggedly built and uses XT60 connector for battery connection. It is small with a high performance
cooling system. Digital LED indicates battery voltage, discharged capacity and discharge current.
2. Power ON

During the discharging process, Press the dial once to stop the
discharging process, the digital LED(A) shows “Stop”.
NOTE:
After the discharge process completes, rotate the button to view the real-time battery voltage every
30 seconds for the first six minutes.
At certain intervals, the slower the voltage reduces during discharge, the better the battery
performances.
This feature can help to select good-performance battery for your race or flight.
