Note:
1. Before installing the protection board, the batteries need to be matched (the voltage difference of each battery should not be higher than 0.05V, the difference in internal resistance should not be more than 5mQ, and the difference in capacity should be less than 30mAh). If the battery is already fully charged, please lower it to the requirement Connect the voltage to the protection board. The batteries must be connected in parallel and then in series.
2. Wiring sequence: first connect the B- wire at the pad position to the battery's total negative terminal (the B negative wire needs to be welded with a short thick wire), and then connect the flat cable; before welding the flat cable, you need to first remove the flat cable from the board Unplug.
3. After connecting the cable, measure the voltage between each two adjacent cables from the header. The voltage of the polymer battery should be less than 4V, and the voltage of the iron-lithium battery should be less than 3.5V.
4. Then measure whether the total battery voltage is equal to the output voltage of the protection board, and the protection board works normally if it is equal.”
