Hello there,  
I would like to send the charge status of an 18V battery to another bluetooth adapter via a bluetooth adapter. How can I use this BMS to transmit the battery charge status and battery voltage to the Arduino and then send this information via a Bluetooth adapter? Which Bluetooth adapter should I use for this? I would also like to display the information on a display that is connected to the Arduino. Which touch display would be best for this application (min. 2,8" but more would be nice)

In this project I would like to build an electric kart with the help of the Arduino. For this I need an accelerator pedal as a potentiometer. Which one would make sense?

If anyone could help me further, I would be very grateful for the respective links to buy the components and the corresponding fritzing parts.

Many thanks in advance

Ench
