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
We had our bike battery from Polaris rebuilt and received it October 2019 and my wife never even had a chance to ride it because of the cold and snow... She maybe Road it half a dozen times in 2020 till she had a biking accident and ended up not being able to use it the rest of the year. Unfortunately when we took it out for the first ride in 2020 this year May 5th it blew a fuse within 5 minutes of having been powered on. Ebikes in Nevada refused to work on them stating that they no longer service Polaris or PIM batteries effective May 2020. I Attempted to contact Nethers and after three or four correspondence and never receiving A response gave up on them and went to High C batteries. They responded they no longer support either the Polaris or PIM batteries either... So I don't know of anybody out there that is refurbishing repairing or providing Alternatives, but if someone is aware of a reputable source that stands behind their work, I have a battery that had been rebuilt the other year that supposedly put out either 600 Watts but only lasted less than 10 runs prior to crapping out... Everybody is blaming the battery management system as the culprit. Don't know what's going on if it's the charging circuit or the rate of discharge is more than the batteries can handle, but after having spent $650 on it I'm feeling quite foolish!
