Hey Robert, welcome to the forum. Coming back in to the hobby from even 10 years off is a huge learning curve. No matter what your question, we are here to help. I'm thinking the video you saw was "Lipo Batteries Explained". I think it was the only video where I showed a charger. Well, for now anyway. If i do what I'm thinking about doing, I'm going to have to build a huge charger and yup, it will be on video.
so post up your questions in the tech section and we will help you out in any way that we can. We will get you in the air.
