The Shark Battery Packs aren't up to par for racing. If I were you I would go straight to LiPO batteries. The Yeah Racing Packs are the best for the money IMO. From what I hear the Turnigy Accucell is a great charger for the money and charges lipo's.

Do you have a specific budget that you want to stay within?

You could go with something like this:
http://www3.towerhobbies.com/cgi-bin...?&I=LXLFW4&P=7

You will notice alot more speed and power with the battery above. A lipo battery won't burn up the motor, I run 2s LiPO packs with my 19T spec motors with no problems.

What kind of charger do you have now?

The battery and the charger that I posted work fine together. The Venom cells aren't very good, not much better than the Shark battery that you are using now. I have always used Integy batteries before I switched to lipo and liked the Integy cells. You will want to upgrade to deans plugs on the battery that I recommended though.

Hi Jurgen,

Well the first question that I have to ask is what speed control do you have? You shouldn't purchase a lipo if you don't have a speed control with a cutout for lipo. It would technically be okay to run a lipo with a speed control that doesn't have a lipo cutout but you are running the risk of over discharging your lipo. Secondly, from your post it doesn't sound like your looking to race necessarily. If that is the case then just try to get your hands on another cheap stick pack, just look for ones that have a higher mAH rating, maybe something like a 3000mAH or there about. Almost every manufacturer makes stick packs like I just described. Lastly, there are many different chargers out there and everyone will have an opinion on which one is the best, but the question that you want to ask when purchasing a charger is whether it does just Lipos or lipos and HiMH or just NiMH. I would suggest that you get a charger that does both types of batteries because you may decide down the road to get some lipos and if you don't buy a charger that does both now you will have to purchase another charger later on.

Later

Duefuss

You are probably using the cheap tamiya plugs now. If you decide to switch to deans you will need to solder one plug onto the speed control and on onto each battery that you have.

Default track

Not to be nosy but where do you live in Michigan? If you are looking to run at a track there is www.larrysperformancercs.com/ for offroad carpet or www.factorytracksraceway.com for offroad dirt. you don't necessarily need to race. I just go to the track with my friends to play around

If thats all you are doing then just go ahead and get yourself some cheap venom, duratax, reedy, trinity stick pack any of them will work. Dont worry about changing the end right away, if you start having issues melting the plugs then worry about changing to deans connectors. Normally outside playing you wont have an issue. Get your hands on one of the cheap duratrax charges. Here is the one that I suggest.

+1 what Adedue said. Not only do you need a cutoff for LiPo, you'll also want a voltage regulator since 2S LiPo is 7.4 volts (as opposed to 7.2 for a 6 cell NiMh pack). Most BEC aren't designed to handle that and you run the risk of frying your servo is more than 6.0 volts get to it. You can race just fine with NiMh batteries if you want to. I do.
