Through searching I see people have used Optima Batteries for their dual battery set up but the batteries are in separate trays. I also found that others use the Odyssey batteries that Overland recommends with its dual battery tray. I have not found anything where people have used the Optima batteries in the Overland dual tray.
Has anyone used the Optima batteries in conjunction with the Overland dual battery tray? (It appears one of the yellow tops fits the dimensions but still wanted to ask the question and see any pics).
BTW.. I have a second gen.
