3.7 V lithium battery from Shenzhen, models 103450, 123048, and 804050, with a capacity of 2000 mAh—Lipo batteries for rehabilitation equipment.

Safety: Equipped with a BMS protection board that covers overcharge, overdischarge, overcurrent, short circuit, and reverse connection prevention. All batteries are fully managed based on factory‑set K‑value data. Specifically engineered with semi‑solidification technology, they resist needle puncture without generating volatility and do not cause fires. Certifications: CB/CEUL/PSE/BIS/KC/IEC/FCC/ROHS/MSDS/UN38.3; can be shipped by air or sea. Tests for high‑ and low‑temperature resistance, anti‑swelling, explosion‑proof performance, liquid leakage prevention, as well as pressure and puncture safety have all met the required standards.
Maximum discharge rate of 15C, high capacity, genuine and non‑counterfeit labeling (suitable for motors, vacuum cleaners, and lights). Long cycle life: 500/1500 cycles. Power capacity remains stable. Low self‑discharge, long standby time, and stable voltage with no fluctuations.
