Power Supply's Portable System

I'm sure that even with the bump controller interface you can still select pre-sets manually. You surely must be able to do so, otherwise how could you charge a battery that didn't have a bump tag on it, such as one of your flying buddies batteries, or whatever?

I haven't got any buddies.......... today had the most I've ever seen there at the heli pad A total of seven of us but not all at the same time. I need to power the charger up to see what possibilities there are but I need the case for that. Like I say, I'll do some more research and see what I can find. Let you know in due course.
