SkyRC BD250 | 250W 35A Digital Battery Discharger & Capacity Analyzer

Description

The SkyRC BD250 is a high-performance, robust discharging and testing instrument engineered to measure true battery capacity, evaluate discharge performance, and prepare packs for storage. Supporting virtually any battery chemistry and cell count up to 35 Volts, the BD250 is capable of continuous discharging at up to 35 Amps or 250 Watts.

Equipped with premium IXYS MOSFETs and an innovative vertical airflow cooling system featuring a large downward-pushing fan and extruded aluminum heat sink, the BD250 maintains stable thermal management under heavy loads. Providing real-time telemetry on voltage, capacity, and current, it eliminates guesswork, allowing hobbyists and competitors to select and maintain the best-performing battery packs.

Key Features

• High-Power 250W Continuous Discharge: Sinks up to 250 Watts of continuous discharge power to test large-capacity, high-drain battery packs quickly.
• Adjustable 35A Current Range: Fine-tune discharge rates from 0.01A up to 35.00A to match exact application loads and battery chemistries.
• Wide Voltage Compatibility: Supports discharge voltage ranges from 5.40V up to 35.00V, accommodating 2S to 8S multi-cell configurations across various chemistries.
• Advanced Thermal Management: Features a high-performance downward airflow fan system and extruded aluminum heat sink paired with genuine IXYS MOSFETs.
• Real-Time LED Telemetry: Clearly displays live operating data including current battery voltage, discharged capacity, and discharge current.
• Comprehensive Safety Alerts: Built-in low-voltage (<5.2V) and high-voltage (>35V) alarms protect the hardware and user during operation.

Benefits

• Accurate Capacity Verification: Measure exact milliamp-hour (mAh) delivery to determine true battery health rather than relying on estimates.
• Fast Storage Preparation: Safely and rapidly draw down high-capacity flight and race packs to recommended storage voltages to protect cell longevity.
• Optimize Race Performance: Test and identify your strongest battery packs to ensure maximum voltage delivery under heavy competition loads.
• Robust Workbench Reliability: Heavy-duty components and high-efficiency cooling ensure dependable, long-lasting performance during intensive workshop testing.
• Compact & Ergonomic Footprint: Space-saving vertical tower design fits easily on any pit table or workbench without cluttering your workspace.

Applications

• RC Car & Truck Racing: Essential pit tool for testing high-current discharge profiles of 2S-6S LiPo racing packs.
• FPV Drone & Multirotor Maintenance: Verify true flight pack capacity and check cell voltage sag before heading out for aggressive flying sessions.
• Battery Matching & Grading: Group packs with identical discharge behavior together for multi-battery setups and balanced performance.
• Off-Season Storage Care: Safely discharge fully charged packs down to target storage levels to prevent chemical degradation over the off-season.
• Workshop Electronics Testing: Versatile electronic load tester for evaluating power supply stability, DIY battery builds, and DC power sources.
