Cool. They settle back down to about 3.60v ? Yeah, that's pretty typical. When you put the small chargers on, did the red light or green light come on? That will tell you whether the black and decker charged your cells to full capacity or not. Once you top them all off, you'll be ready to ride on them. If you have a 36v pack, the voltage should read anywhere from 42v - 43v.7v on your watt meter. Just so you know what to look for when you hook the watt meter up. Later on, when you only use the black and decker to charge (for convenience), it'll show something like 41.7v . If it shows much lower than those then you probably didn't charge all 3 packs up and shouldn't ride it. Once you hit the throttle, it'll go down to about 39v or 38v, though. I'd top them off for the next 4 or 5 charges and then you can get buy just using the black and decker and just top them off when you want to just to keep them all balanced. You probably could get by just topping them off once per month and just check the cells every now and then to see how they are doing.
