36V/48V BMS 10-14s (11s/12s/13s) 30A/40A/60A Lithium/LiPo 18650/21700 Battery Protection Board — 800W/1200W Detection Circuit

Designed for 36V/48V battery packs built from 18650 or 21700 cells, this BMS supports 10-14s configurations (including 11s, 12s and 13s) and is offered in continuous current ratings of 30A, 40A or 60A. Protection functions include overcharge protect, over-discharge protect, abnormal high protect, temperature protect (optional), discharge overcurrent protect, load short circuit protect and charging recovery; a detection circuit is also included. Physical footprints vary by model: 63×48×8MM, 63×48×14MM, 72*55*8/14mm, or 78×60×17mm to suit different installation needs. Cell balancing is handled with balance currents of 83mA or 56mA depending on the version, helping maintain cell consistency and extend pack life. Intended applications are electric bicycles and electric tools within 600W or 1200W, depending on model, providing reliable protection and stable power delivery.
