Assembly instructions:
1, the first battery voltage pairing, difference < 0.1 V.
2, the battery’s internal resistance pairing, the difference of internal resistance < 5 m o;
3, battery spot welding, test whether the voltage is normal;
4, the plate welding nickel sheet;
5. Connect the board to the lithium battery in the order of B0, B1, B2, B+

Points for attention:
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, which will lead to circuit voltage spike, easy to cause MOS tube damage;
3, pay attention, do not let the protection plate touch the water, easy to damage!
4, welding plate, please pay attention to anti-static operation!
