    Hi All, I picked up the kit today with Four Motors, Four Propshafts, Four Props and Two 20amp ESC's and run them on non Lipo 7.2volt Batteries. Keep an eye out for my build blog when i start building.

    Cheers Jon

    That is what I was trying to explain, without the knowledge to back it up. Thanks for the clarification. This old dog is STILL learning. Will wonders never cease......

    Hi jonb
    Esc's designed to work with LiPo's have additional circuitry built in that allow the user to set the low voltage cut off point. This results in a higher cost.
    This is important as LiPos will be damaged if discharged below the manufacturer's specification. I monitor my cells on the model and try not to discharge my LiPo's below 3.5volts per cell.
    Damage to LiPo's is cumulative and irrepairable so unless you want to keep replacing batteries a device that cuts the power below a certain voltage will save money in the long term. Overcharging should also be avoided and the safe storage voltage is 3.7v per cell. A good balanced charger will keep your batteries in good condition and keep you and your models safe.
    The ESC doesn't care what type of battery is used as long as the voltage is within its operating spec. Some ESC's designed for LiPos have a low voltage point of 7.4 volts so will not work with NiMhs of 7.2volts or indeed any battery below 7.4volts. All have an upper voltage limit and if you exceed this they usually issue smoke or fail to offer fwd/rev or good speed control.

    Not sure of difference either, but had a MTroniks non LIPO ESC that worked perfectly well on a SLA cell.
    Wanted more boat performance with a lighter installation and the dreaded grey smoke resulted.
    Often wondered why!
    Think Doug (RN in Munich) could be our best guide.

    I am not quite sure of the difference, but I suspect it has to do with the voltage drop in LIPO's. I suspect the ESC has a lower voltage limit built into it to prevent damaging the LIPO, whereas a 12 lead acid or such could be run down much farther without damaging it. One can use a LIPO ESC for lead acid (or SLA), but I dont beleive one can do the reverse. I have been using the LIPO versions of the ESC's I previously posted simply because of the higher amp rating available.
    I must plead my ignorance on this subject because I shy away fro LIPOs like COVID. Hopefully someone with better knowledge will chime in. Doug????
    This looks like a wonderful build to do. Please keep us in the loop.

    Hope you write a blog on this boat. Have long thought of building one

    Hi All
    Just to follow on ...Lipo ESC. v 12v ESC , can someone explain the difference as Lipo's
    appear a little more expensive . Why ,?
    Can I really use either ?๐Ÿ˜Š

    Thanks
