By HISUN Sector 750 EPS Failu
"Mrs. Smith" doesn't like how loud our Sector 750 is. On a HISUN forum someone said the same thing about his 750. I haven't given it much thought because I've been more focused on stuff that has broken.
So, I used my decibel meter to check ours out. 4000 RPM, Low gear, under 20 MPH . . . . 97 decibels. That's above most ordinances, even state boat noise limits.
AI Overview Ninety-seven (97) decibels is considered very loud and dangerous to hearing with prolonged exposure, roughly equivalent to a newspaper press, a loud nightclub, or a snowmobile. At this level, damage can occur after just 30 minutes, necessitating hearing protection -

Hi All,
I have a 14 mile round trip on level roads to reach the property where I work with my 2025 Amp Crew Ranch (purchased, April 2026). That 14 mile round trip uses 60% of the battery as shown on the gage for a calculated range of 23.3 miles versus an advertised “up to 50 miles” range. A mile or two working on the property gets me a flashing gage and warning beeping by the time I get home. The dealer was good to work with and even with a new battery (yesterday) the results were about the same, although there seemed to be more power and a higher top speed. I own a Mach-e Mustang so I am familiar with how various conditions affect range, but less than 50% of advertised range just seems like there has to be something out of whack.
Now I’m wondering if there is a controller and/or software issue affecting the range and performance. At various points the Amp seems to lose power for no reason and then has trouble maintaining speed. Any ideas?
Also, twice now, the brakes seem to have not released fully. After noticing reduced speed, I stopped and check the rotors and wheel…..HOT! So, now every time I feel less power, I stopped to cycle the brakes and check the temperature. Very annoying. Are there any adjustments to be had?
And yes, as noted in another post, sometimes the switching from forward to reverse or high to low speed feels sluggish or balky.
Lastly, while an electric vehicle powertrain is quiet, my Amp was horrible from a road noise and vibration standpoint. This was easily fixed by locating panels vibrating on other panels or the frame (even the cup holders were vibrating) and installing felt adhesive pads at the contact points (seat to frame, windshield to frame, fenders to frame, etc.). This is a $10 and 1/2 hour fix that makes a significant improvement in the driver/passenger experience. Tire noise, yes, but that’s because of the knobby tread.
I’m trying hard to like my Amp and would appreciate any tips, advice or solutions.

I have a 2021 UV34XL and I am kind of looking to change it up from the orange wheels and maybe do a wrap? Please share photos of any XLs that has been modified to look better and any seat covers recommended.thanks

Hi, I purchased a used Cub Cadet 750 Challenger that seemed like the belt was slipping so I put a new belt in. It still acts like the belt is slipping but now I am thinking it is the clutch?
What is the best way to remedy this problem?
Can the clutch be rebuilt?
Are there aftermarket clutches available?

Hello. I have a 2016 Massimo MSU 500. I was putting on a lightbar and i screwed up and didn't disconnect the battery so when i was taking of the positive cable to put on the power from the lightbar it sparked and now the utv has no power. I turn the key over and all i hear is a chirp. No lights or anything. Everything that comes from the battery to the jumper box up by the battery shows voltage but anything coming out does not such as to the winch or anything like that
