First, pair the battery voltage, the difference is less than 0.1V. 2. The internal resistance of battery is paired, and the difference of internal resistance is<5m Ω; 3. Check whether the voltage is normal after the battery is spot welded. 4. Welding nickel plate. 5. Connect the board to the lithium battery in the order of B0 B1 B2 B Pay attention: 1. Please pay attention to the output power to configure the size of nickel plate. 2. Be careful not to short circuit P P repeatedly, which may cause circuit voltage spike and damage to MOS tube. 3. Be careful not to let the protective plate touch the water, which is easy to damage! 4. Please pay attention to anti-static operation when welding plates! Package Included: 1* Lithium battery protection board
