36V/48V BMS 10–14S (11S/12S/13S) 30A/40A/60A for 18650/21700 Li-ion/LiPo — Protection Board with Detection Circuit (800W/1200W and below)

Overview: This BMS is made for 36V and 48V lithium packs (10–14s, including 11s, 12s, 13s) using 18650 or 21700 cells. It includes a detection circuit and is suitable for systems rated 800W/1200W and below. Specific models are available for loads up to 600W or up to 1200W, depending on the variant. Protection features: Built-in safeguards include overcharge protection, over-discharge protection, abnormal high-voltage protection, and temperature protection (optional). It also provides discharge overcurrent protection, load short-circuit protection and charging recovery to reduce the risk of damage from electrical faults. Performance: The BMS is offered with a maximum continuous current of 30A, 40A, or 60A depending on the chosen model, delivering steady power for electric bicycles and electric tools while maintaining reliable operation. Cell balancing: Effective cell management is provided with balance currents of either 83mA or 56mA (model-dependent) to keep individual cells even, optimize pack performance, and extend overall battery life. Physical sizes: Compact form factors vary by model: 63×48×8MM, 63×48×14MM, 72*55*8/14mm, or 78×60×17mm for easy installation in different pack and equipment layouts. Applications: Designed primarily for electric bicycles and electric tools, this BMS supports a range of use cases and power levels (600W or 1200W models available), offering protection and dependable performance for everyday commuting or professional tools.
