Tom Haeder-odd polarity reversal of LIFPO batteries in Polaris Ranger

[@notshared2543]

Hi Tom have you seen this issue since this video? What did the Dakota tech support say?

Hi. Thanks for your questions. I have not had any problems at all since I made the video about reverse polarity but I have only operated my Polaris EV in the L (Low) and M (max range) modes. As long as I don't use the H (High) mode, apparently I don't exceed the batter BMS range settings. Here is what a nice fellow from Dakota Lithium said: "The reason why you were seeing reverse polarity reading is because one of your battery went into a low/high voltage cut-off. When removing the cables this caused the battery to "wake" back up. We recommend balancing your batteries every 1-3 months. We have a support video explaining balancing your batteries: Support Video Series - Balancing Your Batteries. In addition, more information is available in our How to Balance Batteries in Series blog post." (those are two links but I can't have them as links in my reply to you). Best of luck to you.
