10PCS 7S 29.4V BMS Protection Board with Balance for 18650 Li-Lithium Battery — 15A Multi-Function Charge Module

Pack of 10 high-quality 7S (29.4V) BMS protection boards designed for 18650 Li-Lithium battery packs. Each board is manufactured with careful workmanship to deliver reliable, long-lasting performance and multi-function protection for your battery system. Protection and detection: built-in overcharge detection at 4.25±0.05V and over-discharge detection at 2.5V±0.05V to safeguard individual cells. The board also provides short-circuit protection and is capable of self-recovery; a delayed self-recovery mechanism adds an extra layer of safety during fault conditions. Charging and current specifications: nominal charge voltage 29.4V with an upper working (maximum) current of 15A for efficient charging and discharge operations. Balance functionality is provided with a balancing current of 46mA to keep cell voltages even. Power draw and form factor: quiescent current is under 30uA, helping reduce standby losses. The compact PCB measures approximately 60*40*3.6mm for straightforward installation in battery assemblies. This 10PCS set offers a practical solution for protecting and balancing 7S 18650 Li-Lithium battery packs while maintaining precise detection thresholds and dependable safety behavior.
