The Battleborn Voltage chart has 100% at 2 different places in the chart.
I assume the top one 14.4 volts is full charge when charging and 13.6 volt is a full battery at rest .
But it has been said that you must unhook all loads from the battery and then your supposed to be able to use this Battleborn chart.
The Li chart is supposed to be harder to read then the lead acid chart because the voltage range for the Li is much wider were the lead acid chart is simply 12.7 full 12.1 empty of what you can use
Easy with a lead acid chart when voltage at rest.
