Descrição do produto

Enerkey Lithium Battery Charger Protection Module 3S 40A 12.6V SIB/Lto/Li-ion/Lifepo4 BMS for Car Start

Product Description

Product Overview

The 3S4S40A lithium battery protection board is designed for 3-cell (3S) and 4-cell (4S) lithium battery packs, featuring a 40A high current carrying capacity. It integrates overcharge, over-discharge, overcurrent, and short-circuit protection functions to ensure safe and stable battery operation. Suitable for power tools, energy storage systems, electric bicycles, and other applications, it provides an efficient and reliable battery management solution.

Core Features

High Current Carrying Capacity: Supports 40A continuous discharge current, meeting the needs of high-power devices.

Multiple Protection Mechanisms:

Overcharge Protection: Prevents battery voltage from exceeding the safe threshold.
Over-discharge Protection: Prevents damage from deep discharge.
Overcurrent Protection: Limits abnormal current, protecting circuit safety.
Short-circuit Protection: Quickly disconnects the circuit, preventing equipment damage.

Heat Dissipation Design: Equipped with a heat sink to effectively reduce operating temperature and improve stability.
Temperature Control Monitoring: Integrated temperature sensor to monitor battery temperature in real time, preventing overheating risks.

Wiring precautions:
1. Installing the protective board requires a certain amount of technical electronic knowledge.
2. When wiring, first connect the B- wire at the soldering pad position to the total negative terminal of the battery (the B- wire should be soldered to a short and thick wire) and solder the wired terminal to the battery pack first, and then insert the protective plate.
3. The connection between the battery terminal B- and the protection board terminal B- should be short and thick, otherwise it will cause the protection board to charge and discharge in advance and malfunction.

4. You need to use thick wires when wiring P+/P-. Wires that are too thin and too long will burn the board!
