I' m going to try the supercap option since not having ever to worry about charging batteries is a clear advantage besides no one has commented negatively about supercaps and installing them seems straightforward and simple .
I found the ebay link to the supercaps, three supercaps joined together.
I wonder if this single super cap also from ebay would work?
5.5V 4F Farad Ultracapacitor Supercapacitor vertical config backup .
Or the one on the photo from Amazon?
Most likely three 1.7v 10 Farad super caps are better than one 5.5v 4 Farad supercap? More Farads means greater storage capacity which possibly means longer running time before it stops working? I just looked up Farads, I'm guessing the rest. A knowledgeable explanation would be interesting.
Thanks for all help.
