I figured it out, you have to set the ‘Actual Connected Cell Number’ to 12 and press ‘Set’, you should hear a beep and the Charge and Discharge MOS will open!
Check out @Vincentbraillard build.
He also used ant BMS with 12S10P configuration. Here are his parameters:
Just download the VBMS app from app store, connect your phone via Bluetooth to the BMS and change parameters according to Vincent’s values. That should fix your issue.
Share some pictures of your battery build, I’m interested to see!

If you have a 12s assembly, then why is there a voltage on the lines above 12.The application should not show them at all! There’s 0.You should insulate the loose wires or cut them off. But it’s better to leave it, maybe you want to change the build to 13s or 14s later.
I think the issue will be solved with the settings / parameter update. Unfortunately the VBMS app doesn’t keep my changes. I asked the programmer for support and hope to solve it soon.
I use ANT BMS on my 14S - love it works great - but I recommend you only use it for charging/balancing the battery. When riding find a way to bypass the BMS entirely (I use a bolt/wing nut to quickly swap cables &bypass BMS). Why? Because BMS used MOSFETS to transmit power (just like the ESC) and therefore will overheat/fail just like an ESC unless it’s actively cooled.
The temperature sensors on the ANT - bms are already standing. And four sensors in the kit are installed on the body of the battery itself, two are installed on the contacts themselves + and - they heat up more.
