$2.00e-bike donwtube battery connector with cable 5.5*2.5DC/5.5x2.1DC connector
Charging cable with 5.5DC*2.5DC connector;
Charging port: 5.5*2.5DC port, 5.5*2.1DC port; charging port is installed on our Hailong-01 battery case , polly DP-6 battery case, tigeshark DS-6 case or frame DA-5C battery case.
There are two types of this kind of connector, 5.5*2.5DC and 5.5*2.1DC; 2.5DC connector is normally used for charging current ≥4A; 2.1DC connector is used for charging current <4A;
The male 5.5*2.5DC connector is compatible with 2.1 and 2.5DC port; if you are not sure your charging port is 2.1 port or 2.5 port, you can choose the 2.5DC connector.
If your original connector is damaged, you can just cut the old plug, wire with new connector with the small red cable and black cable; Our 2.5DC connector is with red anode and black cathode as default. For your original charger, it would be better for you to identify the positive and negative cables before wire the new connector.
Note: the space between the contacts are close, it's better to make the other two contacts insulated when soldering to avoid the welder touching other contacts causing a short circuit.
For how to change to the 5.5X2.1DC or 5.5X2.5DC cable from inside of the charger, please check below video:
