2S 7.4V Solar Lamp Circuit Board Continuous Current

1. The difference between the split port and the same port: the default charging current of the split port is 5A, and the positive and negative poles of charging and discharging should be separated; the charging current of the same port is as large as the discharging current, and the charging and discharging are on the same positive and negative levels.
2. Without equalization and with equalization: equalization is to discharge the high-voltage battery cells with resistance when charging, and wait for the low-voltage battery cells to charge up the voltage, so as to achieve the consistency of each voltage and voltage, and improve the performance of the whole battery pack.
3. Before installing the protection board, the batteries must be well matched (the voltage difference of each battery is not higher than 0.05V, the internal resistance difference is not more than 5mohm, and the capacity difference is lower than 30mAh). The better the consistency of the battery, the farther the running distance will be. The working performance of the protection board reaches the best.
4. Connect the batteries in parallel first and then in series, and make sure that the welding is correct (18650 batteries are spot-welded with nickel sheets, and other batteries are welded with solder). Do not use screws to screw the IC on the protection board.
5. Please note or want to leave a message to explain whether you are using a polymer (ternary lithium, lithium cobalt oxide, lithium manganese oxide) battery 3.7V or a lithium iron phosphate battery 3.2V, so as to ensure that the protection board we send is suitable for your battery.
