    Hello, my friend from a distance.
    Sufficient energy is needed to drive class 700 motors. NiMh batteries are by no means unable to stably release their current power and turn off the controllers. The LiPol battery is ideal, and in your case the 3S - 11.1 volts. Motors would work reliably with 2S LiPol cells, but I recommend a minimum capacity of 4200 mA if you want to drive at least 40 minutes in full power. 600 class engines would be good for you. I use LiPol 2S 4000 mA in all models. Two regulators per battery is not a problem with one connector you put into the receiver with the help of a red cable needle to ensure that the receiver is burned. If you have one battery, count on the fact that you will drive max 15 minutes at full power and end.
    In either case, you will need two 60A min. They have a very strong current draw and especially during start-up.
    If you want to make an investment in the future to buy AC controllers and AC motors, it's power elsewhere and very powerful shaft power.
    Then you will need a 400W motor and a 45A regulator.

    HI all,
    I am building a 1/24th Perkasa wooden kit.
    And I have no idea how to power it.
    I have bought two Graupner Speed 700BB turbos that run from 9.6v to 12v.
    I don't want to use a 12v gel battery as the boat will sail like a brick!

    I want to use two coupled 50 amp speed controllers with Lipos, but I dont think I can use them with these controllers as they are for brushed motors and have a bec 5v / 1amp which I think would destroy the Lipo.

    What size Nimh battery pack would you recommend, and would I need two packs or would one pack be enough.
    I have other boats that only have one motor and are smaller than this one so have not had this sort of conundrum!

    I am on a limited budget so cant afford to waste money on trial and error combinations.
    I would be very grateful for any suggestions.๐Ÿ˜ญ
