hello all, i thought that I would share my version of the bad boy capasative charger. it is a true bad boy charger in that it gets its voltage directly from the mains power. I use 120v ac, a 300uf run capacitor and a bridge rectifier to get my dc voltage and current. the 300uf capacitor allows me to charge at around 15 amps constantly, with no voltage tapering off. now when you charge like this one would usually use a timer plugged in to the circuit to turn it off, but Im turnig it off another way. I have built a battery monitoring circuit to monitor the voltage of a 12 volt battery, with my circuit you can switch off power when the battery reaches a preset voltage. in my case that disconnect voltage is 13.8v, the circuit will automatically reconnect at 11.5 volts but those voltages can be adjusted with the 100k pot that is installed in the circuit. hope every one likes it it cost me 60 bucks to build and can charge from 48v to 120v.
just incase you are wondering, the case is from an old ship n shore charger that i bought from e bay and never worked, so i took what i wanted and tossed the rest.
