    LiPo Question

    Am contemplating two 2S1P configurations for SV27:

    4500mAh @30C

    4000mAh @40C

    Any recommendations?

    Zippys or Turnigys (5000mah) from Hobby King.....can't go wrong for the price. Have used both extensivly this season with great results.

        "C" rating is what the batteries "Should " be able to deliver to the controller and motor.

        The controller and the motor/prop set up determines how much current is being drawn from the batteries. Use the higest "C" you can find(afford), the controller will be fine.

          With both those packs you are sacrificing run time for a higher C rating that the SV doesn't really need. That is unless you have a hotter motor/prop setup than stock.
          Don't forget current draw capability of a pack is a product of the capacity & the C rating.
          Lets see.
          4000mah 40C.... 160A capability but lowest run time $25.00
          4500mah 30C.... 135A capability slightly higher run time. $25.00

          You could try these for more run time @ only a few bucks extra.
          5000mah 30C.... 150A capability & more run time $28.00
          5800mah 25C.... 145A capability @ the most run time $28.00

          The prices are based on Turnigy packs

          Since the SV only draws between 40A- 60A, the higher capacity packs at lower C ratings more than cover the load & give you more 'fun' time between charges.
          I run the 5800mah 4s 25C packs & Himodel 5350mah 25C 2s packs in other boats on bigger motors/props & have great run times & no heat problems.
          Just my thoughts.
