Have tried DEKA's over the years , seemed OK.
Trouble is the genuine HD batteries ( made by DEKA anyways !) work out cheaper from the HD dealer , strange but true !
Have had mates try Odyssey and other "exotics" over the years and always they come back to "genuine".
With battery Fighter junior tenders I have had "Genuine" batteries last 7 years on a few occasions before now.
Will be interesting to see how these "$88" SSB batteries pan out
Good to hear, was just checking out batteries for my springer which has the rtx20l-bs in it at the moment.
But the htv1 looks to be the better option.
