For my next project, I want to make a 'fuel gauge' for a trolling motor battery in a boat. My intent is to use an arduino, a Hall Effect sensor, a temperature probe, and the analog port to read voltage and estimate battery life remaining.
After some googling, I see that such algorithms are usually in the realm of proprietary technology, which makes me think its harder than I've planned for.
Is this a reasonable thing to attempt? And if so, where can I start looking for reliable battery information regarding discharge rates, temperature, voltage, and state of charge?
