    Mixing battery capacities / brands / etc

    I have an old emaxx and I have several different batteries with different capacities, brands, etc. They are all NiMH. The Traxxas EVX-2 manual says "Do not mix battery types (NiMH or NiCad), brands or capacities. Use the same voltage and capacity for both batteries. Using mismatched battery packs could damage the batteries and electronic speed control."

    I suppose I could see different types and different voltages, but what is the problem with using different capacities? How does it affect the ESC?

    If you are running parallel it won't matter. If you are running series you could over discharge one of the packs.
    This will TOTALLY work, saw a guy on YouTube do it
