Wet! I said this was an estimate and what is on some volt meters. If you use a different % that is up to you. I use 12.5 is when to charge. If you want to use 12.2 great! I do not want to get into a contest over the %.
MY point is/was the % charge can be estimated by voltage and fance expensive monitoring is not really necessary.
