I have a Lithium battery pack and a separate battery charger. I was trying to figure out the state of charge of the battery from the 8 lights on the battery charger marked Led 1, through 8 Lights 1 through 7 light up after 1 hour of charge. Light # 8 takes much longer to come on. Is it OK to stop charging when I have 7 lights on? Thanks Leo
