I charged my battery (Ni-MH 7.2V 900 mah) for my brand new firebird commander today, but I got rained out. I used to use a stoplight bulb discharger for my rc car batteries (Ni-cads) when I did not get to use them. Does anyone out there know if I can use a bulb discharger for these kinds of packs? (How many bulbs? #1157 bulbs?) What do you guys do besides holding the throttle down to discharge your packs?
