Need some setup help with my Smart Ant BMS

I know… BMS’ses are evil!.. Very evil! ( @Flightjunkie )

However. I’ve got one (an Ant BMS **), and would love to see how evil they are!

I have just finished building my 12S12P Li-ion pack with Sony VTC6 cels, and the BMS does connect nicely to my phone, and shows data. (see images).

Some Sony VTC6 data
(data sheet: http://queenbattery.com.cn/index.php?controller=attachment&id_attachment=38 )
Rated capacity: 3000mAh
Nominal capacity: 3120mAh
Nominal voltage: 3.6V
Standard charge current: 3A (1C)
Charge end voltage: 4.20V
Max charge current: 5A
Max continuous discharge current: 15A (5C) / 30A (10C) with 80°C temperature cut
Discharge cut-off voltage: 2.0V / 2.5V

Note that I’ve set the cell count to 12. The cell count in the image is still set to 24 (it’s an old screenshot)

Anyone here who can help me to set the values to the correct setting?
note. The temp sensors are not connected.

Thanks for making me laugh.

Sony VT6 cells are a good choice. Sorry I can’t help you with the BMS setup.

Please keep us posted how this battery performs over time.

Be careful what you ask for!
