    lipo or two stock batteries

    alright well i was at 2 different hobbystores this weekend and ive heard different things about the two the one said that 2 stock batteries are faster than the lipo would be

    and the other store said a 3s lipo will make the rally produce 50-60mph

    which is true

    First statement would need some detail to be considered a fact. What configuration, compared to what LiPo, etc.

    Second statement is 100% correct and it's awesome.

    Once you try lipo you won't go back.

    the guy said running the 2 stock batteries in series will give me the same power out put as a 3s 11.1v lipo

    but they do equal out the weight of the car considering one battery on one side

    3s is 11.1v 2nimh in series is 14.8 maybe not faster but lipo will perform better, has more punch, and delivers the same rate from the beggining until the end, nimh as soon it started to discharge their performance decrease. Overall I prefer Lipo.

    (1) 3s is more than plenty and it is the max your esc can handle, you can hook up (2) 3s in parallel but never in series not even (2) 2s in series.

    I would think 3S would be uncontrollable in that thing. You would need some killer tires. 2S IMO might be the perfect mix.

    2 2s in parallel from great run times.

    I think the Rally has better handling characteristics with a single batt. Single 3S is insane (in a good way) and single 2S is nearly perfect. Good speed and runtime.

    That is correct and the Rally manual even points that out for anyone who may be skeptical.

    Please also consider that lipos require some knowledge. Certainly I do not know very much about nimh but am very comfortable with lipo. However there's a lot to learn. How to charge, balance, discharge, handle, and store, become important.

    2 stock Traxxas batteries in series with 31t pinion 50 mph on radar

    [IMG][/IMG]

    2 2s batteries in series with 31t pinion 54 on radar ran out of road probably will go faster brakes work real good

    [IMG][/IMG]

    2 2s batteries in parallel my favorite way to run any of the 1/16 Traxxas cars

    [IMG][/IMG]


    Running the Traxxas 1/16 platform since June 2009 without any burned out electonics just got to keep a eye on your temps. The esc has shut down to level 1 and level 2 protection a few times when I wasn't paying attention with no ill effects

    the car could reach a faster speed with 3cell but that is just straight line speed. but you will have to gear it correct and find a flat surface. then practice.

    The max is 3s 1800mah but it varies depending on the manufacturer so to be sure I will go a little under maybe 1500-1600.

    I cant imagine what it would be like with one 3s. the stock battery is still blowing my mind. From my understanding 3s may have a lower voltage(hp) vs series nimh. but 3s is capable of putting out more amps(tq) vs series nimh .another benifit is lower weight with lipo. Im a little fuzzy when it comes to gearing 31t is the speed gear(top end) Meaning a slower start(compared to stock gear 28t) but you get a higher top end. In order to run the car on 3s drifting,bashing etc.. do i need to drop a gear to deal with the heat issues of the car under higher load...im confused...lol This is my first electric car. i started out with nitro. can someone pm me. i just picked up a inteigy motor heat sink with fan and i also have a 10mm fan on my esc. were do i tap for power?

    Man, you can do way over 50 on 3S if you gear it up but your going to have to keep a real close eye on temps. I know you could run higher than a 31t pinion, ive got a 35t... so 3S with a 35/45 would be sick on 3S. The light weight and higher discharge rate of a lipo would be more beneficial than the extra voltage of the dual stock batteries IMO. They are heavier and limited in how many amps they can supply. Honestly though, if you want to go REALLY fast... what Radicalray is doing with 4S is the way to go.

    if you want to keep the car balanced rather than run a 3s on one side, run 2 x 2s LiFe . i have two from maxamps, 6.6v each, not as crazy as two 7.2 lipos, but way more balanced than a 3s on one side. my merv can still do backflips although you have to get off the gas just before it lands as its still enough power to blow driveshafts apart.

    The rally is designed to be run with a single pack. It says right in the manual that this is how its balanced for drift style running.

    to be honest the rally wasn't designed at all, they just took the slash and thru on some new parts and a new body, the slash runs better with twin packs, the merv runs better with twin packs. you do the math.
