Search on google. You will find it. I'm not saying this to be mean or anything but I remember finding it like that.

1st Google hit using "bulb discharger" as the search query: http://www.balakracing.com/bulbdischarger.htm

I built that discharger, and it will discharge a 9.6v 3000mah in about 20 minutes, plus it was only about 10 bucks to make.

I would recommend that the temperature of the battery be monitored during the discharge process. I have managed to seriously overheat some batteries during the discharge cycle, and it's just not healthy for the cells. One thing I've tried is putting the battery on a small bag of ice as it discharges.

The main reason why the batteries overheat is because of the number of bulbs. If you reduce it down to four it will take double the amount of time but will not hurt the batteries.

I use one of my extra Truck Fog lights. Works beautifully. Like was said before....ensure that you monitor the temp or you will easily kill your battery.

I have used an R/C car and it worked, now I have Ni-Mh's but my neighbor still uses an R/C car.

BTW, NiMH packs do not need to be discharged. They can be left as-is after use, ie. with a charge on them. Only NiCd packs need discharging.

I know, maybe you didn't read my post right?:confused: or was that even directed toward me?

Nope, it was directed at the whole thread. :)

How does this lightbuld thing work. Does it use up the battery to power the light?

No, it uses belly button lint to power the lightbulb.

On a serious note, yes, it drains the battery by powering the lightbulbs. This is useful for NiCd battery packs, but should not be performed for NiMH packs.
