6S 22.2V 18650 Lithium Battery Equalization Board 6S 25.2V Polymer Battery Equalization Board Product description Description: The equalizer board is suitable for lithium battery pack without equalization, and the charging date makes the batteries in the battery pack fully charged at the same time. Technical Parameters: Equalization voltage: 4.2V Equalizing current: 66mA; Suitable for 6 strings of battery packs. Product Size: 37.3 * 25.8 * 2.4mm Precautions: The equalizer board does not with charge and discharge protection function, can not replace the protection board, when the battery is charged, the first full charge of the battery through the resistance discharge, the current shunt balance. The balance sheet does not charge and discharge protection function, can not replace the protection board. When the battery is charged, the first fully charged battery is discharged through the resistor to equalize the shunt. Solder Joint Description: B - Connect the negative of the battery pack? B1 is connected to the middle of the battery 1 and the battery 2; B2 is connected to the middle of the battery 2 and the battery 3; B3 is connected to the middle of the battery 3 and the battery 4; B4 is connected to the middle of the battery 4 and the battery 5; B5 is connected to the middle of the battery 5 and the battery 6; B6 Connect the battery pack positive?
