i have tried a mix of batteries in mine over time and for starters i find dynamite battery packs are garbage. i use duratrax dtx 1600 in my trucks where space is limited,they work really great .i ended up using also Reedy Wolfpack 4200...3600...2400 ni-mh and have been using them for the past 5 years.i get around 1 hour of run time without lights and around 45 mins with lights give or take with the larger ones 4200.the smaller ones i use for quick runs in between times when i am getting loaded at companies .i won't use lipo's in any of my trucks i am too afraid of the fact that some will catch fire easily for some reason.but i agree with the statement earlier here ...it depends what you pay for ..there are cheap batteries and a little more pricey better batteries
