What Lipo For 1940/6?

Of course I could wire up the needed harnesses. The needed y connectors are actually an off the shelf product, with the series connector for the controller being the only real soldering that would be needed.
For a power supply, I do carry a 25 amp(more than enough!) power supply, which I use myself, for about $130. There are a few power supplies that would also work, but your "do it right the first time" philosophy tells me you want more than "just enough".
