Product overview
The SKYRC BD250, product code SK-600133, discharges batteries and measures their capacity to support battery selection and preparation for storage. Its operating envelope is 5.40-35.00V, with adjustable discharge current of 0.01A-35.00A and maximum continuous discharge power of 250W. Listed battery configurations cover 2-8S LiPo, LiFe and LiHv, 6-23S NiMH and NiCd, and 6-32V lead-acid batteries, subject to the voltage envelope. Configuration-specific tables give cutoff voltages and discharge-current values, so the 35A maximum does not apply across every listed configuration.
The unit measures 136.6x104.8x107mm and weighs 879g net. Its cooling architecture combines a finned heatsink, a temperature-controlled dual-ball-bearing fan and downward airflow, while IXYS MOS transistors support sustained discharge. A rotary control sets cutoff voltage and discharge current and starts or stops operation. Digital LED displays show current and battery voltage or discharged capacity. Battery and data connections provide the electrical interfaces; the supplied equipment comprises the BD250, an XT60 discharge cable, a fuse and a manual.
For analysis, the BD250 can connect to Windows software and export battery-voltage readings at 30-second intervals during the first six minutes. After discharge finishes, rotating the control every 30 seconds allows real-time voltage viewing during the first six minutes. Capacity display accuracy is ±3%, while current and voltage display accuracy depend on the measurement range. Low- and high-voltage alarms are specified at less than 5.2V and greater than 35V respectively, and sleep-mode current consumption is less than 100uA. These functions make it a battery discharge and analysis instrument.
