(free shipping in the United States, $30 shipping to Canada and no sales tax outside Colorado) Why an EarthX lithium battery for your personal watercraft? It’s a dry cell technology and can be mounted in any direction without worry of acid spillage! The weight is 80% lighter so you can go faster and the vibrations of hitting the waves does not damage or effect the battery! No maintenance needed in the off season, can sit for 6+ months with no need to trickle charge it and it is still ready to go next summer!
