I am brand new to Arduino so please excuse my ignorance.
I have an EV conversion with 32 LiPO4 batteries. Cell balance is always an issue and the BMS I have will cut power if any cell drops below 2.6volts. I would like to have advanced warning and wish to build a system which will read each battery and turn on or off an LED associated with that battery (ie 32 LEDs) when it reaches 2.8 volts so that I know I am getting close to cut off and also know which battery it is so I can boost it to balance the pack.
I see some Arduinos have up to 50 i/o pins. Can I do this or am I completely off base.
Thanks for any advice you may have, Pete
