Using Li-ion battery on Tongsheng wich connection

[pkers]

Hello and a good day from the Netherlands.
I want to connect a battery formaly used on a e-scooter for my Tongsheng mid engine on my bike.
The battery uses an C13 euroconnection ( 3 poles) en the motor comes with a 2 threaded connection, plus/minus.
How do i connect the battery to the engine?
Thank you in advance,
Peter

If you can show the actual connectors involved, it will make it easier to help you find connectors you can use to make a cable to connect them.

The results I get for C13 are for an AC cord to the wall; that is normally only on the charger-to-wall side.



I've seen it misused on the DC side of charger-to-battery connections, where it could lead to a fire (because people will fail to understand a charger is required between it and the wall, and find a cable that will connect that directly to the wall).

The most likely thing you will end up doing is taking a mating cable for that connection, such as an extension cable like this, cutting it in half, and using just the half you need, along with a cable (perhaps another extension) for the middrive side connector type, and splice the wires together at the cut ends with the correct polarity that you will determine with a multimeter.


Is this the only connector on your battery?

Which pins on it have what voltages, relative to the battery negative, as tested with your multimeter or voltmeter?



Also, Is the battery the correct voltage range for your middrive, *and* can it supply the required current (amps) to the mid drive under worst case highest load? (there are multiple Tongsheng mid drive models and versions, so we don't know which one you have, and we have no information on your battery at all).

Hello Amberwolf, thanks for your reply.
At this moment i'm short of time to place photos.
But, on the battery, there is de male connection of the cable.
On the motor there is a 2 wired cable, plus and minus.
So, my simple guess was, take a cable with a female c13 and use the two threads pos and neg. The earth wont be used.

Use a voltmeter to identify which two pins have power.

I would personally use that connector, because some time in the future, someone,not knowing any better. might plug a 220-240VAC mains cable into it. If it was a thief who stole the bike, maybe that is a good result,

I recieved the motor. In a few days i'm going to mount it and let you know the results.
First of, i will check the pos an neg on the battery.

Update: the motor is running, speeds up nice. Just one minor dispay problem. That's for a new thread.
Thanks for the replies.
