UTV BOARD Support & Announcements

Don't have much good to say about Massimo but my 2014 MSU500 still has the original battery.

Yes! The U1 battery format is one of the shortsighted design issues in the 550 series. It is completely unsuitable for a UTV, but that is the hand we are dealt.I assume that you use the same battery in your 410. Just buy the biggest and best unit that will fit in the tray. I bought an AGM 350 CCA battery from Amazon. (ASIN: B0CKSKHDM6) There may be others that fit in that space, but my issue was resolved using the Sealed AGM (Absorbent Glass Mat) construction rather than the flooded lead acid design. And NEVER buy a N-EVERSTART battery from the Big Wally if you want to get home! 🏁

Yeah, mine is a Linhai platform. I don't have much time on it, but it's been reliable. I have had some starting issues, but I believe that's battery related.

While I can fully understand Joe B's unhappy experience and his recommendation to go elsewhere, I believe that his unit is/was a HiSun. Those units have been shown to be very suspect, and Massimo was way undercapitalized to support the dealer network and their customers. On the other hand, my 2020 T-Boss 500-F (with the steel box w/dropdown sides) is a Linhai chassis. Except for a few design quibbles (front hood access, oil change mess, inadequate hitch mount and excessive reach with the steel box, overly bright display at night, etc), I have found that the Linhai version to be a solid, reliable, entry-level SXS. I've had the steering wheel loosen up (6 Phillips head screws) and the windscreen brackets needed realignment. I also replaced the 300 CCA U1 Lead acid battery that was OEM, with a 350 CCA AGM U1 battery. That solved the occasional cold start stall and kick back against the starter. The OEM flooded lead acid battery is just too small. Works OK in my lawnmower, though. 😒 I use mine for general banging around my land that has somewhat rough terrain, and I am also equipping as a fast-response vehicle to fight remote wildland fires. Bottom line is that I wouldn't ever consider buying a used 2019 or earlier Massimo or any other brand that uses the HiSun chassis of any vintage. 🏁

Well, the dealer has had my 750 for seven weeks now for a number of issues that he has been putting off. Not a happy camper! However I was told that Hisun felt it was possibly an MCU problem and it was swapped out while it was in a no start condition. It  seemed to run OK, so the original was put back in and they had a no start condition once again. They then replaced the MCU and felt that there might be an internal intermittent connection to one of the connector pins that was the cause of the codes and running issues. I hope to get my 750 back very soon and if it passes MY smell test, I will call this issue fixed at that time.
