There are several benefits to a dedicated fpv or low voltage battery such as reliability in that you don't have to worry about brown outs caused by punching the throttle, though the down side is more weight. As far as the battery Tatu is my first choice. Thanks! I made it because I remember the topic being somewhat confusing and overwhelming when I first got i got into FPV. I try to keep it updated too, and thanks to people notifying me of good product to or tips it has been getting good updated. I was gone for a couple of months, see anything goes that should be updated or added?
