Battery cannot be charged

Hello everyone
I own a first-generation SP140. It still has an ON/OFF switch on the battery.
I had to replace the battery’s BMS because the output voltage was no longer 88.8V, but only 60V.

Paul sent me a new BMS with Bluetooth. It works perfectly, even with the app. Output voltage is over 88.8V.

Now I have the problem that I can no longer charge the battery.

Is there anything I need to be careful about with the new BMS?

I have the feeling that there’s a missing authorization for the battery to charge.

I would appreciate any help.

Greetings from Switzerland

When I plug the battery into the charger, the charging MOS turns green.
The voltage in the app is 89.8 volts and when I measure with the multimeter I have 89.9 volts.
On the charger, the display shows 95.46 volts. But Ampere remains at 00.00

Is there anyone in Switzerland who has an SP140? Then I could test whether my charger is faulty.

Thanks for your help
