Product Description
Built for professional-grade equipment that demands sustained high-voltage power, this 14.8V pack doubles down on capacity with a 4S2P architecture — 8 matched 18650 cells delivering 5000mAh (74Wh). The dual-parallel design not only doubles runtime vs. 4S1P equivalents but also halves effective internal resistance, enabling cleaner voltage delivery under pulse loads common in medical aesthetic devices, IPL systems, and portable clinical instruments. An intelligent BMS with per-cell-group monitoring ensures all 8 cells age gracefully together.
