Enerkey 3S-10S 40A Bms Lithium Battery BMS with NTC Li-ion/Lifepo4/Lto/SIB Lithium Battery Protection Board
Product Overview
Enerkey 3S-10S 40A (EK-BM3R10S40A) lithium battery protection board is a safety protection solution tailored for multi-cell lithium battery packs. Utilizing advanced circuit design and intelligent management chips, it provides comprehensive and precise protection for lithium battery packs, effectively extending battery life and ensuring safe use.
Product Features
* Wide Range of Applications: Supports 3S to 10S lithium battery packs, flexibly adapting to battery systems with different voltage requirements. Perfectly compatible with electric bicycles, drones, and energy storage devices.
* Multiple Protection Functions
* Overcharge Protection: When the battery charging voltage exceeds a set threshold, the charging circuit is quickly cut off to prevent overcharging and avoid dangers such as battery swelling, leakage, or even explosion.
* Over-discharge Protection: Monitors the battery discharge voltage in real time. Once it falls below a safe value, the discharge circuit is immediately disconnected to protect the battery from over-discharge and maintain its healthy state.
* Overcurrent Protection: Accurately detects the charging and discharging current. If the current exceeds the rated range, the protection mechanism is activated instantly to prevent battery overheating and damage due to excessive current, ensuring circuit safety.
Short-circuit protection: In the event of a battery short circuit, it can disconnect the circuit in a very short time, preventing serious damage to the battery and equipment from the short-circuit current and ensuring safe use.
High-precision monitoring: Employing high-precision voltage and current detection chips, it can acquire battery status information in real time and accurately, providing reliable data support for the protection functions and ensuring the timeliness and accuracy of protection actions.
Low-power design: While ensuring the normal operation of the protection functions, it greatly reduces its own power consumption, reduces the consumption of battery power, and extends the overall battery life.
High-quality component selection: High-quality electronic components are selected, which have undergone rigorous quality testing and aging tests, exhibiting good stability and reliability, and can operate stably for a long time in various harsh environments.

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!
