Product description

Size:3S 12V

1.Description:
It is a lithium battery protection board.It is to protect the charged and discharged battery and prevent the battery from damaging the battery due to overcharging or over-discharging.
2.Feature:
1).It supports over-current protection,over-charge protection,and over-discharge protection.
2).It supports short circuit protection,and the delay can be automatically restored.
3).It has a balance function,which makes the voltage of each battery more balanced.
4).It adopts reasonable wiring circuit and has a long service life.
5).You can add a temperature switch to expand the temperature protection function.
3.Parameter:
1).Product Name:Lithium Battery Protection Board
2).Overcharge Voltage Range:4.25V-4.35V
3).Over-Discharge Voltage Range:2.3V-3.0V
4).Maximum Operating Current:20A-25A
5).Upper Limit Instantaneous Current:35A-40A
6).Quiescent Current:30uA(Max)
7).Effective Life:30000 Hours(Min)
8).Internal Resistance:100mohm(Max)
9).Balance Current:45mA
10).Charging Voltage:12.6V-13V
11).Work Temperature:-25℃~85℃
12).Work Humidity:5%~95%RH
13).Size:56*45*4mm
4.Balance Description:
1).In order to make the balance effect better,please use a 13V switching source for charging (the self-stop current is less than 30mA).
2).The equalization current of the equalization IC is about 45mA,and most of the 12.6V lithium battery chargers on the market will stop automatically when the charging current is lower than 100mA.If there is no equalization,no charge will come in,causing the voltage of each battery to be unbalanced.
3).Regarding the voltage drop between the battery voltage and the output terminal voltage,the working principle of this type of protection board is negative protection.Some of them will have a voltage drop of 0.1V-0.3V when they are combined,and the voltage will be reduced after charging and discharging several times.Voltage drop,this is normal.
4).The
