straight track running on a big track will get you 15-18min. IMHO..and thats continuous driving with zero crashing...for bashing you should get at least 20-25 min...you'd be surprised at how long 15-18min is...even 20-25min.........i think having 4 sets of lipos is perfect...but thats just my experience.....and since your geared for 45mph..you'll most likely break something before you run down ALL your packs if your doing crazy bashing in a flux...or you might even get bored .. lol
