Hi y’all,

First post here.
I’m new to all this with scooters and battery’s so excuse my lack of knowledge.

I bought a used 48v16Ah battery pack for a scooter project that I been wanting to try out. Tried to find some information about the battery pack online but it’s hard to find (or I suck at google). When I measure the battery voltage I just read 3 volt. From reading on this forum I learned that the controller in this battery turns off the power when it’s not getting a signal to stay on fro CANbus or similar.

Dose anyone here have knowledge of this battery pack? (Found similar battery’s on this forum)
Does anyone know where to buy a matching contact for the outlet?
What pins am I supposed to send a signal to? I guess I need to use a arduino nano or similar.
And how do I charge it. Will I be able to hook a Lithium ion charger to the positive and negative terminals and then it will charge whiteout any "charge" signal?

Thanks in advance!

So I found this image online and managed to get 48v out of the battery. But the battery is cutting power when I try to pull some current from it. I’m working on making a 3d printed plug. Just need to find some pins that will fit. Still no success with the CAN protocol tho.

Hi Ludde
Did you have any luck with the battery testing. Have you found how the can works.

Thanks

Hi,

I haven’t totally given up but other things took my focus so I did put this project on holt.
But now I’m thinking about getting the battery’s out and buy a BMS to control them. Maybe 3D print a holder.

Best regards
Ludde

Hi Filleka.

I can’t see that I receive a message anywhere. Is it possible to send DM’s here?
