4S 20Amp (3.2V LiFePO4 Cell) Battery Charge Protection Board with Balancing for 12v Batteries (10006831)
This 4S 20Amp Battery Charge Protection Board is designed for use with 3.2V LiFePO4 cells, providing balancing and protection during charging to ensure the longevity of your battery pack.
Features:
1. The use of high-quality materials, product quality is guaranteed
2. With balanced charging function, the battery loss is smaller
3. Components arranged neatly, more exquisite and beautiful
4. The product has over-charge and over-discharge short-circuit protection, etc., which is more safe and reliable
5. Wide range of applications, suitable for a variety of industrial DIY occasions
Parameters:

Over discharge discharge voltage: 2.550.1V
Balance starting voltage :3.4050.05V
Note:
In order to achieve better consistency and balance of the equalization effect, try to use a switching source of 15V to charge (self-outage current below 30mA). Because the balance current of the equalization IC is about 65mA, and most 14.8V iron lithium chargers on the market, the charging current detection is less than 100mA, and there is no charge in the balance, resulting in the voltage imbalance of each group of batteries. On the battery voltage and the output voltage there is a voltage drop problem, the working principle of this type of protection board is negative protection, just combined some will have 0.1-0.3V voltage drop, cycle charge and discharge several times will reduce the voltage drop voltage, which is a normal phenomenon. Charger try not to use 14V power supply, 4 series of iron phosphate battery full charge is 14.4V, 14V power supply will appear insufficient phenomenon, the protection board will not protect, has been charged, long-term use has an impact on battery life, thank you for understanding.
