Ok guys here I am again. I have several 6V 5AAcell NiMH battery packs that I use for model airplanes. My problem is discharging them. I have used a 6V 50mA light bulb and watched over them the correct amount of time but really want to build a simple circuit to cut the discharging off after 5.5V has been reached. Variable voltages and discharge rates would be great since I use several size and voltage packs but simple is the best. I have scoured the internet but nothing gives me what I need except expensive balancers. I did see one USB PC software ran balancer but it would not match my needs. Any ideas or links would be great especially a simple schematic. I keep thinking pots and LEDs for dicharge rates but how do I make it cut-off when 5.5V is reached? I could use a 7805 and a bulb but that would drop me to 5V and that is too low. I always get great feedback here and it is sooooo appreciated.
