Battery measure help

Hello guys,

I am making an escooter, therefore I have a lithium battery at 24VDC with a maximum am 29VDC at 20A. How can I measure the battery voltage using an arduino?

Thanks.

Google:

Arduino Voltage divider.

Uh, thanks for this, I am kinda new in this zone. And if you can help me find a MOSFET or Relay for this kind of power (MAX 20A).

A couple FQP30N06L or IRF3705N MOSFETs in parallel might work.

China suppliers sell voltmeters for less then a dollar but there is shipping.
