I flew for a number of years with two 22 lb batteries without every needing the "spare". I then switch to a single Odyssey PC 680 17 lb battery and switched it out every 3 years (stuck used one in riding mower) and flew for over 15 years using this configuration. Never had a battery problem with either, but saved weight and money with the one battery.
But, my view is if you are not comfortable flying with a certain configuration, then don't. Fly with a configuration that you feel secure with and you will enjoy flying all the more.😄

Le Roux, Agree a great product, but I am more concerned with the engine battery backup. Therefore I have 2 batteries . Since no longer flying instruments, I can still fly looking out the window, but if the engine fails --- Then you know what is trumps!! Neil. Realy nice product |
