I can't honestly say I would recommend buying Venom batteries unless price is a huge issue. Like said before if you are not using the starter box often the 1800's would probably be OK but if your starting two or three cars off of it all day you may want a little more capacity. I think for the reciever pack though I would definately go with something a little nicer. I have been running a promatch 5 cell in my 8th scale and have been very happy with it. I think they're like 12 bucks of their website.
