The polymer is wired in the same way as lithium iron phosphate, supporting both the same port and split port.
1; B-line to the negative of the lithium battery pack
2; connect the cable (make sure the cable is unplugged from the protection board, start wiring from B-, 8-connect the total negative pole of the battery pack, the second line B1 of the cable is connected to the first string of the positive battery of the lithium battery pack) The third line B2 is connected to the positive pole of the second series of batteries of the lithium battery pack, followed by
3: Insert the cable after checking the error.
4: Take out the C line
5: Whether the total voltage of the lithium battery is equal to the voltage of C-to the positive pole of the battery (the equivalent board is working normally)
Precautions
The B-, C-, and P- lines should be connected with thick wires and ensure that the pads are soldered correctly to the positive and negative terminals of the corresponding device.
Before installing the protection board, the battery must be matched well (the voltage difference between each battery is not higher than 0.05v, the internal temperature difference is not more than 5mΩ, the difference is less than 30mAh), the protection board is to protect each string of batteries, as long as there is a string of batteries If the voltage is too high or too low, it will be protected. The better the battery consistency, the longer the battery life, and the best performance of the protection board.
A single battery needs to be connected in parallel to the required number of battery packs, and then the battery packs are used in series.
When connecting the battery packs in series, please ensure that the voltage of each battery pack is the same. If it is different, please fill each battery pack separately and use it in series. In the discharge test, the circuit with the fastest voltage drop is the differential power.
