CW10020 100V/20A Lithium Battery Capacity Tester – Precision Discharge Testing for Professionals
Engineered with high-precision shunt resistors for accurate current measurement, ensuring ±0.5% voltage and current accuracy. Heavy-duty aluminum alloy casing dissipates heat efficiently, ideal for prolonged 20A discharge cycles. Wide compatibility tests lithium-ion/LiPo/LiFePO4 packs (2-30S) with adjustable cutoff voltage (2.0-5.0V/cell) and real-time data logging via USB. Backlit LCD displays voltage, capacity (Ah/Wh), and temperature simultaneously. Industrial-grade MOSFETs and 12AWG silicone cables handle 100V/20A loads safely. Essential for EV battery maintenance, solar storage diagnostics, and drone pack health verification. Bulk discounts available for repair shops and OEMs. Waterproof rotary encoder ensures durability in workshops. Includes PC software for cycle testing and CSV export. Ships with calibration certificate and 2-year warranty.
