Lithium Battery Charger Protection Module (BMS) 16S 30A 60V
The Lithium Battery Charger Protection Module (BMS) 16S 30A 60V is a compact PCB-mount Battery Management System designed for lithium-ion or lithium-polymer battery packs comprising up to 16 cells in series. It provides essential safety and battery-management functions — including over-charge, over-discharge, over-current, short-circuit, and temperature protection — while also performing passive cell balancing to ensure uniform cell voltages across the pack. Its 30 A continuous discharge rating makes it suitable for medium-power electric bikes, scooters, solar storage systems, portable power packs, and DIY lithium battery builds.
Features
- Supports up to 16 cells in series (16S) — suitable for nominal 60 V battery packs (full-charge up to ~67.2 V for Li-ion cells).
- Continuous discharge rating typically 30 A.
- Passive cell-balancing circuit to equalize cell voltages — extends pack life and improves safety.
- Full protection suite: over-charge cutoff, over-discharge cutoff, over-current protection, short-circuit protection.
- Balance-lead harness included for all 16 cells.
- Compact PCB layout, suitable for DIY battery pack builds, scooter/ebike batteries, solar backup packs, and high-voltage battery systems.
- Compatible with common lithium-ion chemistries (18650/21700 prismatic or cylindrical cells), lithium-polymer (Li-Po), and LiFePO₄.
