    i am looking into buying spc 2s 50c 2500mah batteries for my 1/16 mini erevo vxl

    1. can i charge them with the traxxas dual id ezpeak charger?

    2. does the "C" rating matter? i noticed it is twice as high as traxxas lipos dont want to have any problems runnung them.

    1. Yes, that Traxxas charger has legacy balance ports.
    2. Higher C will not hurt anything.

    What does "c" rating mean? What I read online is it is the continous current and says to figure that out do mah x c rating so it would be 2500 x 50 = 125,000 so the continous current is 125 amps... the peak current for my esc says 150 amps. Can peak current go higher than 150 and ruin esc?

    I don't have a dual iD EZPeak charger, but it should work.
    Just pop off the plate in the front so you can use non-iD LiPos.

    Those SPC LiPos are great! I have 3 of them for my MERV!

    The c rating on a battery is what (the mfg claims) the battery is capable of putting out.

    Short answer, no, the higher c rating won't hurt your truck in any way.

    Long answer, think of the battery like a big gas tank. The c rating is the size of the hose coming out of the tank, which determine the max theoretical flow rate. , The true flow rate though is determined by the esc. The esc is the valve (carburator or fuel injectors) that feeds the gas into the engine. No matter how big the hose is (c rating), the valve will only flow as much gas as the engine is asking for.

    The only downside to ultra high c ratings like that is that it's not a good idea to depend on the esc's low voltage cutoff. I recommend getting some sort of aftermarket voltage checker to keep your batteries in good health.
