I am an avid r/c plane flyer and would like some ideas on a battery backup system for a model plane.
would like to use 2 battery packs (4.8v) in such a way that pack a is the master pack and pack b is the backup.
if pack a should run 'low' i want pack b to switch in and totally isolate pack a (in case pack a has developed a fault), also when pack b switches in it will sound a loud buzzer / flash lights (time to land).
the best i have come up with is a relay driven by transistor / mosfet, the problem here might be the time that the contacts change over.
any ideas would be appreciated. I know very very little about electronics
thanx in advance
