DC Electronic Load 25W 4A Adjustable Constant Current Tester with LCD for Battery Capacity Testing

DC Electronic Load Tester 25W 4A LCD Adjustable Constant Current Aging Tester Discharger Voltage Current Power Battery Capacity Description A compact DC electronic load designed for controlled discharging, battery capacity testing, and power measurement. The unit offers adjustable constant current control up to 4A with 25W maximum power dissipation and an LCD readout for voltage, current, power, and accumulated capacity. Key benefits Controlled testing: Provides adjustable constant current loading to discharge batteries and DC power sources in a predictable, repeatable way for accurate capacity and endurance checks. Clear measurement: Builtin LCD displays realtime voltage, current, power, and accumulated capacity so you can monitor test progress and record results without additional instruments. Practical power handling: 25W dissipation and 4A maximum current support a wide range of small batteries and lowvoltage power supplies used in hobby, , and lab settings. Saves time and uncertainty: Replaces improvised load methods with a single device that sets and holds current levels during aging and discharge tests. What it does Adjustable constant current load for discharging batteries and loading DC power supplies Realtime monitoring of voltage, current, and power Accumulated capacity tracking to measure battery mAh over a discharge cycle Suitable for aging tests and repeated discharge cycles Compatibility and usage Compatible with most DC power sources and battery chemistries provided operating voltage and current stay within the device limits Intended for use with small battery packs, singlecell lithium batteries when used with proper safety procedures, NiMH, lead acid and DC power supplies within safe voltage range Bench use for hobbyists, technicians, educators, and product development teams Key attributes Function: Adjustable constant current DC electronic load, discharge tester, capacity meter Performance: Up to 25 watts power dissipation, maximum current 4 amps Display: Integrated LCD for voltage, current, power, and accumulated capacity readouts Form factor: Compact bench unit suitable for desktop testing and portable field checks Typical use scenarios Evaluating battery capacity after or assembly: Discharge a battery at a set current to measure mAh and verify whether capacity meets specifications. Stress testing DC adapters and power supplies: Apply a steady load to confirm voltage stability and behavior under realistic operating current. Aging and cycle testing for development or quality checks: Run repeated controlled discharge cycles to evaluate endurance and track degradation over time. Why choose this model This electronic load delivers essential discharge and measurement functions in a simple, easytouse package. It is appropriate for routine battery capacity checks, lab troubleshooting, and component validation where controlled constant current and clear readouts are required. Safety and operation tips Ensure the device under test operates within the load tester maximum power and current ratings. Use proper wiring and secure connections to prevent accidental shorts. Monitor the LCD readouts during tests and stop the discharge when the target capacity or voltage limit is reached. Contents and what to expect Electronic load unit with LCD display and control knob or buttons for current adjustment Clear readout of voltage, current, power, and accumulated capacity during discharge cycles This DC electronic load provides straightforward, repeatable performance for testing and validating batteries and lowvoltage DC supplies where 25W and 4A capabilities are sufficient.
