Buy a WPS from a local dealer not Amazon. They have always taken care of me. I have walked into my local power sports dealer with the bad battery after two years and they filled out the warranty claim no questions.Been running wps last 3 or so years. No issues. I threw one across the shop and it still works. Id get a 300cca one. The weight difference is negligible.
Have a Noco. Seems to work fine but cost more than wps. Wps has a really good warranty I hear although I haven't had to use it
