I suppose i should add i have a 4s Turnigy 20C 5k pack that i run in my RC8 for about 12-15 minutes also with no worries - stays really cool at 100-110f too =)
Got every thing i ordered today. soldered some deans on to the 10g batt wire, did a balance charge at 1amp every cell in my 3s and 2s packs were with in .01 volts . havent had a chance to try the ez-run motor in the wifes rig yet but im thinking it will be perfect just like every thing else. The Turnigy Accucel-6 charger is fantastic so far, for 35 bux you cant go wrong.
