These people at Dakota are incredible people. I have had some problems with a $1600 battery I bought four years ago. There were a few questions asked, and then, I received a brand new battery. I will not buy another brand of lithium battery ever. Eric and crew not only want my business they DESERVE my business. I am not able to say how much I appreciate Dakota Lithium. By the way, I own several other Dakota batteries and have had zero issues.I am glad to know there are still companies like Dakota still around
