## Description

Product description

Review: Lo recomiendo - Took the plunge and converted to lithium.Works perfectly in my Yamaha. It's so much lighter than the old batteries, which made swapping them out easy. The instructions were clear, and my cart is noticeably faster. The best part is how long the charge lasts on our hilly course. A bit of an investment, but feels worth it.
Review: Great Batteries! Working as should - This unit fit perfectly in my dual battery box with room to spare. I was able to put my bottle jack (in it's own plastic case) in the battery box as well as the shunt and a sheet of 1" closed cell foam to take up all of the space and prevent side to side movement. I went from 90lbs of battery weight on the tongue to 56. This battery has two rope carrying handles as well.
