Awhile back I read that some guys have switched over to lifep04 battery, I thought I’d give it a try and bought a Nermak 6.4/4.5A with 28.8 WH and gave it a try. It fired up the bike just fine and took the bike for a ride and all was good, went camping for the weekend and after about a 1/2 drive the dash light got dim and the battery went dead . Looking at the case you can see a bulge . Perhaps I just got a bad one. Are You guys that have switched over having any issues ???
