SIMPLE, ROBUST,
AND POWERFUL
AND POWERFUL
Upgraded from BD200, BD250 is not only a powerful discharging device but also a precise measurement tool for battery capacity.
It takes the guesswork out of choosing the good-performance battery for your application. BD250 offers a maximum of 250 Watts/35 Amps to discharge your battery and will test virtually any battery type or size, any chemistry cells.
It's stylish but small with a high-performance cooling system and uses MOSFETS from the well-known IXYS, to make sure it can discharge at 250 watts continuously.
Breakthrough Cooling System
A unibody and larger fan pushes air downward through an extruded aluminum heat sink. As air passes vertically through the heat sink, it absorbs heat and carries it out.
Due to cooling efficiency, BD250 can discharge at 250 Watts continuously.

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 a good-performance battery for your race or flight.

Easy-to-Use PC Software for Data Analysis
PC software supplied with the BD250 is easy to use, intuitive. There are two discharge mode: 1. Constant Power; 2. Constant Current.
The software can automatically sense battery cell counts and recommend a minimum safe discharge voltage.Discharge tests may be viewed in Amp Hours, Watt-hours or Minutes. Results can be graphed as Voltage vs. Amp-hours, Watt-hours, Minutes.
With PC software connected, BD250 allows you to export the battery voltage value at 30 seconds intervals (for the first six minutes).
