The Difference Between the Split Port and the Same Port: The default charging current of the split port is 8A, and the positive and negative poles of charging and discharging must be separated; the charging current and discharging current of the same port are the same, and the charging and discharging are at the same positive and negative .</div><div>2. Without Equalization and with Equalization: Equalization is to discharge the high voltage cells with resistors during charging, and wait for the low voltage cells to  up the voltage to achieve the consistency of each voltage and improve the performance of the entire battery pack.</div><div>3. Before installing the  board, the batteries must be well matched the voltage difference of each battery is not more than 0.05V, the internal resistance difference is not more than 5m Ohm , and the capacity difference is less than 30mAh. The better the battery consistency, the farther the distance can be run. The working performance of the  board is better.</div><div>4. The batteries should be connected in parallel and then connected in series, and ensure that the welding is correct  batteries are spot welded with nickel plates, and other batteries are welded with solder. Do not use screws, it is easy to burn out the IC of the  board.</div>
