    LiPo on Brushed motor?

    We have a stock rustler with a 7cell NiMH & xl-5 esc ..we switched our motor to the Firebolt 15t 540 and a 17t pinion gear. The battery we have doesn't last for more than 10 minutes on a full charge. My sons getting a bit tired of that... I want to switch to LiPo but not sure if we should get a 3s or 2s. I have read the power ratio of the 7cell NiMH is close to a 2s but I wasnt sure if we can get a 3s in case we want to upgrade to brushless later. So, can we run a brushed motor on the 3s or should I just get the 2s to be safe? Whats your opinion on brand and also what charger to get? I've seen this one seems to be popular http://www.ebay.com/itm/150950676972...84.m1436.l2649

    I would save your money and NOT go LiPo until you go brushless. Go brushless sooner than later (as soon as you can afford it!) As I told someone earlier today, everything is better with brushless...longer run times (better efficiency), more power/speed, etc.

    I would love to go brushless, trust me. Its only a matter of time.. My 8yo son is just learning this car and brushless would be way to fast for him. I do however want a little bit longer run time. Although I think I just figured out that the ESC was set up for lipo Low Voltage Detection and I just switched that off. Maybe that will gain us some play time. I still would like some info on the 2c vs 3c for right now and some brands of battery/chargers that are good.

    The Traxxas EZ Peak Plus is a nice little LiPo charger for a good price (also charges NiMh):

    Go with a 2S LiPo (7.4V); a 3S (11.1V) would toast a brushed rustler motor very quickly...it's only designed for 8.4V!

    Come to think of it, your stock ESC is only rated for 9.6V as well...

    Yeah, smoke is bad. Make sure you get at least a 30C battery; C-rating represents how fast a pack can discharge. If the C-rating is too low for a given load, the pack can literally "puff" (which means it's toast). Puffed packs can start a fire. And you're out fifty bucks.

    I just ordered two of these SPC 6500mah 2S 50c batteries.

    I've been using the SPC 5000mah 2S 25C batteries and they've been great so far.

I have the stock XL5 ESC and it has a flat plug on it and these come with banana plugs...holy moses there is a lot to take in on these things. Every time I get ready to order I see something else I need to make it work lol....So do I need to pick this up as well? http://www.amazon.com/Venom-Bullet-P...universal+plug
