Hi,

Iam building an electric scooter with these specs/parts:

- ASI BAC 8000 inverter
- qs205 v3 motor
- 16S11P Molicell P42a diy battery with smart ANT 300A bms, 2.6kWh
- eggrider v2 and koso DB EX-02 as displays

I want to configure the BAC8000 correctly and need the temp sensor that qsmotors is using in the qs205 v3. I know it´s a KTY83/122 but I don´t know the beta value which determines the temp rise/fall per voltage. Glad if somebody could help me out here :D

Here´s some eyecandy of the project, shown with another inverter in it, a VESC 75 300:

I think I’m close to an answer here, but am a little confused by the formula the spreadsheet is doing, can anyone help?

I also have the QS205 with KTY83/122, what is the math to calculate the voltage at the following degrees celcius?

Voltage at 0 C - (guessing 0.70V)
voltage at 25 Celsius
voltage at 50 Celsius
voltage at 75 Celsius
voltage at 100 Celsius
voltage at 125 Celsius
voltage at 150 Celsius


Sorry I know it’s a old thread but one of the few with my exact question. All help is appreciated.
