I don't do anything special for charging, although I do have a heavy insulated metal safe box and some fiberglass mat stuff like the 'liposac' thing... but I don't use them. Maybe I should use them more. I don't think many guys do any of that.
I do make VERY certain that I'm charging at the right settings... amps and volts. I use the ICE charger and have a profile set for each pack.
Yes the car can keep up with the fast nitros... and if it doesn't... all I have to do is gear up a tooth.
I also just picked up a truggy and put a .21 in it so I can join the nitro fraternity also... but so far I have not had anyone try to stop me from racing hte electric. But they want me to do fake pit stops to make it fair.
Now if we could get all the tracks to allow lipos in mod 1/10 4wd....
