I made this cutoff unit to go along with my standard 10 1157 bulb discharger.
Anyway, while discharging my packs, I have to hold down the switch. I am using all the equipment listed there besides a smaller project box i bought by accident(d'oh! )
Being that I have to sit there holding the switch, it kinda defeats the purpose of this unit. I have tried using a 100,60 and 10 ohm resistor. The 10 ohm resistor worker properly but cutoff at about 7.4v. The 60 cut off a bit higher also but the switch must be held down. The 100 cutoff about right, but I had to hold the switch.
So, here's my question. What did I do wrong? It's a PITA to sit there and push down a small switch .
Also, my first post here.
