I'm trying to save my expensive 12S and 14S Lipo batteries on a High Voltage EDF project. The ESC is currently being controlled via an Uno... I'd like to add in some code and a circuit for telling me when my expensive batteries drop below a preset value. This will be in addition the Low Voltage Cutoff built into the ESC. Here's how I'd like the ops to work: For my 14S packs, I want an LED activated when voltage drops below 3.3V per cell, in this case, 46.2V. That way, I have a visual warning I'm getting low [u]before[/u] the ESC LVC engages. I don't need a numeric display, just a red LED turning on at a preset warning value. A fully charged 14S pack runs close to 60V, so this might require some creativity?
