    Question 8 batteries in a UDR?

    Has anyone tried setting up 8 batteries in their UDR for extra long run time? Basically 4 sets of 2 batteries in series, all hooked together in parallel.

    The voltage should stay the same, will it fry anything if I do this?

    The weight of extra batteries would
    probably kill the run time a little
    Besides the high temps

    Do whatcha like

    in addition to killing your run time and motor, you'd also be killing your suspension. Assuming you're using 2S packs, that's about 6.5lbs of extra weight.

    I think it would be best if this never happens. It seems unnecessary and unsafe. The ESC on the UDR cant handle 8s (assuming you are using 2s lipos) and may catch fire, maybe even the lipos too. 6.5 lbs of lipo on fire would be a spectacular sight. Dont do it.

    Way too much weight. The truck would ride like crap with that much weight. And you would most likely have temp issues as well. Itís always a good idea to let the vehicle cool down a bit between battery packs. JMO. Like said, do whatcha like, but be forewarned that you may end up with a big ball of parts.

    If you change out the stock ESC for a Hobbywing MAX6, then you can run 8s.

    in parallell wouldn't it still be 4S, but just extra run time,... not crazy speed, but able to drive longer?

    what if it was just 2 extra batteries?
