This is phenomenal. I just got a PP 24v Polaris Ranger for my kids, but the battery life is awful. Did you see improved battery life or performance with the replacement batteries over the PP ones? Great video man.
you mentioned that the positive blades were larger, and I saw you change the small cable on the left positive to right negative, but I didn't see you change anything on the yellow wire - so how did the yellow wire/connection fit the right battery positive blade if it was now smaller on the new battery?
Timothy Dike, you don't really need a part number brother. Just Google 12v12ah battery. Just make sure it's a gel cell lead acid. You'll get millions of options. The part numbers will vary by the maker and the stamp users of the battery. But they are all the same.
