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 everyone and I hope that is not a too forward questions for us newbies.
My husband and I are ready (next Spring) to open our newly developed nudist campground in Iowa and we are now looking for interesting activities to host.
Don't worry we are not going to try and sell you a membership because as of 2 weeks ago all of our 50 campsites are sold out for the 2024 season.
It was my job to sell site and now that is complete i am looking for interesting actives host for weekend.
We have 300 acres of woods, grassland, swamps and 2 small ponds/lakes and dozens of miles of riding trails.
we have gotten county approval for the complete 300 acres to be clothing optional.
We think we have a great spot for a weekend or several day ATV / mudder event.
Clothing would be optional for all participants and plenty of room for overnight camping and outdoor group showers.
Now we are looking to you pro ATV riders to let us know if you think your group of people would fit in with ours.
Feel free to ask anything you would like to get a better idea of what we offer.

After three years, my Sector completely died. Something caused the hot wire under the seat from the charger to disintegrate, so the batteries weren't being charged. The batteries weren't charging 100% anymore, so decided to convert to lithium.
As most others have done, I went with 4-48v batteries in parallel, as I believe that will be plenty of amp-hours for my needs, but can always add more if needed. I went with LiTime wired CAN batteries and mounted their digital gauge on the dash above the current one, which fit perfectly. I didn't think the existing battery brackets worked well for the new batteries, so made my own out of aluminum L rails, which makes it much more secure (and saves a few more ounces :)). Since I wired them in a 'balanced' configuration, I had to make all new cables from 0/1 gauge wire and 8mm posts. I updated the DeltaQ charger to profile 233. Cleaned everything up (I must have vacuumed 20 pounds of dirt!), put it all together and... wham!
So far, it definitely is better than with the original AGM batteries. Sustains speed better going up hills, and seems to have plenty of reserve current. The difference in weight with 4 LiPo vs 8 AGM batteries surely doesn't hurt!
Thanks to everyone on this forum, but special shoutout to GNFO who was a big help.
A few questions:
In the 'any tips' thread, EVSupport mentioned reprogramming the Sevcon to reflect the new discharge curve of the lithium cells, but I didn't see any more info about that or how to do that. Is there any more info about that?
Have folks replaced the onboard 12v battery, and if so, with lithium? I'm not sure why there is a 12v battery; why didn't they just step down the current of the 48v system to provide power to accessories?
Is there a recommendation as far as charging with the lithium conversion? As far as I understand, it is better to let lithium batteries discharge somewhat (but not completely) than keep them charging all the time. What do you think?

I bought a used RTV 900 and was told it is a 2012. I thought I would verify that. I can't find anywhere I can look this up.
KRTV900A61057114 is the product identification number.
Thanks for any help.

2021 T-Boss 410 — and yet another story from someone who bought one brand new without thinking twice about the fact there's no real service department like you'd find at an actual dealership.
The Problem:
Around 20mph, it bogs down like it's choking on something. Pedal to the floor, it sounds like it wants to go, but it just won’t. Makes no difference if it’s in 2WD or 4WD—same sluggish result. Reverse works fine. Shifts between 2WD, 4WD, and neutral without issue.
I’ve searched online but can’t find anything specific that matches what I’m (admittedly) guessing might be wrong. Truth is—I have no clue what the fk the actual issue is, and I don’t have the kind of mechanical memory others seem to when tearing these apart. That said, I’m good with my hands and can follow directions—I just don’t have any clear ones to follow right now. Any help or pointing to the right direction would be appreciated- next closest massimo service center was "fk you" miles away they said,
