915 Generation 5S5 String Battery Charging Protection Board BMS Module 18V2

The protection plate is used for 5 series lithium- batteries, mainly for power tools.
It uses an IC dedicated to 5S lithium battery as a processor to detect the real-time voltage, charge and discharge current and temperature of each battery.
Stable various charge and discharge protection functions, such as overcharge protection, overdischarge protection and short circuit protection.
Low power consumption, the working current is about 25uA, and the quiescent current is about 6uA.
Choosing the right protective plate and using it properly is critical to extending battery life. The power module is a kind of electronic components, do not take pictures without professional of electronics, otherwise it will be easily damaged!
Be to read the wiring carefully wiring, and the sequence of the series connection of each battery must be . If you are not , do not wire it!
This protection board is used to the battery from overcharging and overdischarging. It cannot replace the charger. A charger for lithium batteries is still required when charging!
Note 1: Wiring 0V (B-), 3.7V (B1), 7.4V (), 11.1V (B3) 14.8v (B4) 18v (B+) strictly according to the , do not intentionally short-circuit!
Note 2: After the cable is connected, it needs to be there is output.
Note 3: When 5 groups of batteries are connected in series, that the voltage of each group of batteries is the same. If not, fully charge each group of batteries separately and then use in series. During the discharge test, the group of batteries with a rapid voltage drop is the poor battery.
