1 Cell 10A Lithium Battery Charging Protection Module

**This protection module is not suitable for lithium iron phosphate batteries**.

The single-cell 10A lithium battery module is a professional solution for protecting and safely charging high-current single-cell lithium batteries. This module is suitable for 3.6V or 3.7V batteries and manages currents up to 10 amps. The product dimensions are 23.6x11.3x3.4 mm, making it easy to install in confined spaces. The overcharge protection voltage per cell is set between 4.25V and 4.35V, and the recovery voltage after overcharge is set between 4.05V and 4.15V. The delay for activating overcharge protection is 1000 milliseconds.

The single-cell battery charging protector of this module provides full protection against over-discharge. Its minimum voltage is set between 2.30V and 2.50V, and the recovery voltage is set between 2.90V and 3.10V. The overcharge and over-discharge protection current is 16 amps, and the over-discharge delay ranges from 50 to 200 milliseconds. The single-cell 10A lithium battery BMS module includes short-circuit protection with a delay of 5 to 100 milliseconds, and recovery is achieved by disconnecting the load.

This single-cell 10A battery module is capable of charging the battery with a 10A current and automatically activates additional battery charging protection. It is designed using professional ICs and MOSFETs with very low internal resistance (down to 3 milliohms), delivering stable and reliable performance under high-current conditions. The single-cell 10A lithium battery BMS board is highly suitable for use in high-current equipment such as power tools, small motors, model aircraft, and professional electronic devices.

With its compact design, high current capacity, and comprehensive battery protection, this product is an ideal choice for technicians and professional users looking to enhance battery lifespan and equipment safety. The single-cell lithium battery charging protection module ensures the battery operates without damage and with optimal performance under various operational conditions, while also being easy and quick to install.

Note:

1. The **B-** and **C-** wires **must** be connected using thick wire, and ensure that soldering is done correctly and according to the device's positive and negative polarities.
2. Before installing the protection board, balance the batteries. The voltage difference between each cell should not exceed **0.05V**, the internal resistance difference should not be more than **5 milliohms**, and the capacity difference should not exceed **30mAh**. The protection board monitors each battery string and will activate if the voltage goes too high or too low. The more uniform the batteries are, the longer the overall battery life will be and the better the board will perform.
3. First, connect the cells in parallel according to the required quantity, then connect the sets in series.When connecting two battery sets in series, make sure the voltage of each set is the same. If they differ, first charge each set separately to full capacity and then connect them in series. During discharge testing, the set whose voltage drops faster contains weak batteries.
4. Do not mix strong and weak batteries together. It is best for the capacity and internal resistance of each set to be close to one another.
5. 
   Never connect multiple protection boards together in series.
