I have a 2004 Boom Trike Lowrider. It came with a Berga (European) battery. It's time replace the battery, but I have found that the correct Berga is not available in the U.S.
The European batteries have recessed lugs that are flush with the top of the battery, not like American batteries with the lugs sticking up above the top of the battery.
Has anyone replaced their battery in a Boom Lowrider? I think an American size group 26 might fit, but there is a clearance problem between the battery lugs and the body bracketry.
I got no help from the Boom Dealer in Florida when I asked them.
