BMS NMC 3S 15A DALY (i7g5)

DALY BMS NMC 3S 15A (I7G5) is a compact battery management system designed for 3-series lithium-ion (NMC) battery packs. It supports 15A continuous discharge current and protects the battery pack from over-charge, over-discharge, short circuit, over-current, and voltage imbalance. It is commonly used in 11.1V lithium battery packs made from 18650/21700 cells for power tools, DIY batteries, solar lights, and portable electronics.

The DALY 3S 15A NMC BMS is a hardware protection module used to manage lithium battery packs containing three cells connected in series (3S configuration). The BMS constantly monitors individual cell voltage, pack current, and operating conditions to ensure safe battery operation.

If any abnormal situation occurs—such as over-charging, deep discharge, short circuit, or excessive current draw—the BMS automatically cuts off the circuit to protect the battery pack and connected devices.

The module also includes a passive balancing system, which helps equalize voltage between cells during charging. This improves battery efficiency and extends battery life.

With its 15A continuous current capacity, the board is suitable for medium-power devices, DIY battery packs, and portable electronics that operate around 12V lithium battery systems.
