I am opening this thread as a place to list companies and individuals that can help PIM owners refurbish or up grade their PIM battery packs.
Hi-C Battery is another source for rebuilding Polaris/PIM battery packs. In January 2020 they told me that they are relocating to a different building so will not be taking additional orders for pack rebuilds until March of 2020. Quote: "The cells of today are a better chemistry than just 2 years ago. We can increase the capacity and performance of your battery almost doubling your bikes range. Our cells are fresh from the factory so you will always get the newest cells available. Don't settle for a stock battery that has been sitting on the shelf for years, losing capacity and performance all the while. Contact us today to discuss your battery rebuild options." email@example.com
I've made several inquiries and have had customers try. NO RESPONSE!
