I have a tranzx bl15 but no charger. Can I buy a 3 pin charger with same output, and just replace the connector with a 5 pin connector? What are the pinouts on the bl15?
May I ask how you got the battery open? I have one like these and I can't seem to get it apart without completely destroying the plastic case. (Battery and e-bike are in working condition, connector on the battery is broken).
I have the same battery, I could open the case without breaking it. Try with a knife to open on the side of the two screws, there is some glue on it, open this side first. You have also take the screws from the charging jack
@@mituguyen4030 Thanks, a knife sadly did not work for me (just broke off) but I was able to get it open in the end. I did damage the case a bit but I can reassemble it. I ended up using an Ifixit prying tool for the part of the case that was easy to separate (just went through it to separate the adhesive if there was any) and hot air, a flathead screwdriver and a hammer for the hard to separate side. If anyone else has the same problem, start from the side where you can easily slip a prying tool between the case, open it enough to insert a screwdriver and move to the hard to open side. Use a little bit of hot air and a hammer to move the screwdriver. after a few cm the case kinda "jumped open". From there it was easy. PS: I would not recommend doing this if your case is easier to open than mine. Try using the gentle techniques first (prying tool, knife, ...)
i have now reset the 2 orange wires, and now the batteri puts out 35v :-) But the charger still wont charge... i am considering installing a standard non smat BMS
@@patrickhvid1314 We do not accept 36V Tranzx batterier for repair BUT this was for a local bikeshop and he had allready replaced both the motor and the controller on the ebike to generic ones so we could use our own BMS. You should look for german Tranzx videos, they should be more familiar with this battery.
