The charging connector will be 5.5x2.1DC or 5.5x2.5DC connector as default; if your original battery uses the mini XLR 3 pin charging connector, you can choose the 3 pin connector for the batteries; normally for plastic chargers or charging current less than 4A, the default charging connector is 5.5x 2.1DC;

For the discharging connecttor, the default connector is 2 pin connector(female PLA0274 and male PLA0273); if your ebike runs larger current, it's better to use 6pin connectors(female PLA 0239 and male PLA 0238); Normally most of the ebikes for power less than 750W will use 2pin connectors.
