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

High-level protection suite: This 36v/48v BMS provides overcharge protection, over-discharge protection, abnormal high-voltage protection and temperature protect (optal) to safeguard and extend the life of Li-ion / LiPo packs such as 18650 and 21700 cells. Built for electric bicycles and electric tools, it supports systems rated up to 1200W depending on the model. Stable current handling: Models are available with maximum continuous currents of 30A, 40A, or 60A, and include discharge overcurrent protection, load short-circuit protection and charging recovery functions to avoid damage from electrical faults. Compact footprint for flexible installation: Choose from sizes 63×48×8MM, 63×48×14MM, 72*55*8/14mm, or 78×60×17mm to fit various 36V or 48V setups in bikes or tools. Cell balancing: The BMS offers balance currents of 83mA or 56mA (model-dependent) to keep cell voltages matched and improve overall pack performance and lifespan. Application range: Designed specifically for electric bicycles and power tools, the boards suit systems within 600W or 1200W (model dependent), delivering the protection and dependable performance needed for daily commuting or professional tool use.
