minus-squareBev's Dad@lemmy.calinkfedilinkarrow-up7·1 month agoYou can absolutely accurately calculate the percentage of a lithium battery. I do so every day with solar setup I live on. Even after months floating between 20% and 80% the batteries stop charging at 99.5% and would shut off if I hit 0-1% You just need to use a well calibrated shunt.
