Connect battery to Bafang motor

[marcoredit]

Hi,

I prepared a Li-ion battery for my mid motor Bafang, and now I try to understand how to connect to the motor.
The motor has 2 cable: one red (positive) and one black (negative), but I don't know wich connector I have to buy to connect motor to battery.


Thank.
Mark

It's whichever connector you have on the battery, or have chosen to attach to the battery. Those connectors in your picture look like some kind of bullet connector, but I can't tell what size. Cutting off and replacing cheaper types of connectors from both battery and controller are pretty standard. I presume the controller is built into the motor on that kit, since there is two wires to the battery on it.

The two more popular choices are 4mm bullet connectors from the RC world, or Anderson power poles, in 45 amps size. Andersons are best used with 12g or less wire. So if you have 10G 4 mm bullets fit those ok.

There are larger sizes for andersons and bullets too.
