Battery Discharger &
Analyzer
It displays real-time battery voltage, discharged capacity and discharge current.
It can test battery capacity that helps select batteries with the desired capacity.
It saves time when users wish to store their large capacity batteries.
It helps activate the best performance of your batteries for competition.
SIMPLE, ROBUST,
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.
Simple and Intuitive Operation

Test virtually any type, size and chemistry battery.
BD250 is a voltage oriented discharger, virtually any type of battery can be operated. Accepted voltage ranges from 5.40V to 35.00V.
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
BD250 is a voltage oriented discharger, virtually any type of battery can be operated. Accepted voltage ranges from 5.40V to 35.00V.
With PC software connected, BD250 allows you to export the battery voltage value at 30 seconds intervals (for the first six minutes).
