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

Overview: High-reliability BMS designed for 36v and 48v battery packs built from 18650 or 21700 cells. Supports 10-14s configurations (including 11s, 12s, 13s) and is suitable for electric bicycles and electric tools, with model-dependent power ratings (600W or 1200W in some models; certain boards rated 800w/1200w). Equipped with a detection circuit for monitoring and protection. Protection features: Provides comprehensive safeguards including overcharge protection, over-discharge protection, abnormal high-voltage protection, and temperature protection (optional). It also includes discharge overcurrent protection, load short-circuit protection and charging recovery to guard against electrical faults and help avoid damage. Performance: Available in maximum continuous current ratings of 30A, 40A or 60A depending on the chosen model, ensuring steady power delivery for devices up to the stated wattage limits. Balance management is handled with balance currents of 83mA or 56mA (model-dependent) to equalize individual cells and maintain pack health. Form factor: Compact, space-saving PCB sizes vary by model: 63×48×8MM, 63×48×14MM, 72*55*8/14mm, or 78×60×17mm, allowing flexible installation in different pack layouts. Applications: Specifically engineered for use in electric bicycles and electric tools, delivering the protection and performance required for systems rated within the listed power ranges. Ideal for improving safety and extending the service life of lithium/LiPo battery packs.
