http://www2.towerhobbies.com/cgi-bin...1&I=LXJG59&P=7 debating if i should get theseif that list is about correct all i need to know is a choice between chargers and batteries. im going to be bashing it around my backyard and probably at the sand dunes or some other place like that. would like around

well lmk if i forgot anything because i was just going by pretty much what misbehavin said a 10-15 min runtime so if thats possible thatd be sweet. i already have 2 ib3800s 7 cell but something haoppend to them and i dont think they work right so if someoen on here is an expert with them or someoen knows somsoen who can fix them itd be cool if you could tell me! id def. appreciate that! i also have a bunch of crappy 1500 and 3000s what can i expect the runtime on those to be with a good charger? like 5 min? also if i had paddles and i was running in the sand dunes will it make me lose any runtime or power/acceleration?

any answers will grately be appreciated! and as you can tell im very new to the whole electric thing.
