so I did the hump pack upgrade. got the hpi plazma pack 1.6mah 6v. now my truck is killing this battery in less then 1/4 of a tank. have gotten a replacement battery twice from my lhs and each time after charging it just dies quickly. wondering what hump pack you guys recommend to get because this is getting annoying. is the pack too low on amps or is it just not strong enough for my maxx? cheers
