Assembly instructions
1, the first battery for voltage pairing, the difference <0.1V.
2, the battery's internal resistance pairing, the difference between the internal resistance <5m ohms.
3、Spot welding the battery and testing whether the voltage is normal.
4、Solder the board to the nickel sheet.
5, according to B0 B1 B2 B + order to connect the board to the lithium battery

Cautions.
1、Please pay attention to the output power to configure the size of the nickel sheet.
2, pay attention not to continuously short circuit P+ P- repeatedly, there will be circuit voltage spikes, easy to cause MOS tube damage.
3, attention, do not let the protection plate touch the water, easy to damage!
4, welding the board, please pay attention to anti-static operation!
