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?

Help Please!
Last year my Mule started running bad and was hard to start. NOT a battery or starter problem. I replace the carb with one of those cheap Chinese carbs from Amazon. Problem got worse. So, I replaced the fuel pump, one from Kawasaki, fuel filter and lines. Then replaced the fuel pump line to the engine. Finally bought a Kawasaki carb. Everything was ok till I filled the gas tank with fresh gas then it started running bad and hard to start again. The tank is clean. Gas is fresh, AGAIN. Filter is new. When running it has an occasional misfire. Managed to burn about a gallon out of the tank. Runs better. Replaced the gas cap in case it wasn't venting. No change. When running, if you try to go full throttle, it bogs down. The gas is good. I use it in my mower with no problem. The stater was replaced about one year ago and the flywheel cleaned inside. Still seams like a fuel problem but I'm at a loss. It's going back to the mechanic shop today. We use the Mule every day, live on a farm. It's never sat up. It has 1045hrs on it. New battery and starter.
Any ideas?

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,

As with any forum you join, there is a requirement for an obligatory introduction... and that seems fair. How else do you get that first post in there without jumping in with some stupid question right out of nowhere?
Hi. I'm Space Ghost. Well, not really, but that was my call sign on my last deployment before an IED made me non-deployable, and I an now retired/disabled, and living on my wonderful VA disability. I did almost 28 years in total between the Army, Army Reserve, and National Guard. 1 deployment with the Reserve (Desert Storm) and 3 with the Guard (1 pre, and 2 post 9/11)
Married (going on 30 years) one of each. (both out of the nest)
My vehicle is (at least not yet) not a UTV, however, it is an ATV, A 2001 Kawasaki Prairie 400.
BTW, That's Brandy, my former PTS/TBI service dog on the bike. RIP old girl. She's internet famous. Perhaps you've seen her before...
The reason I'm here is that Arthritis is starting to set into my wounds and my mobility is getting worse. I will be selling the quad bike soon, and going with a SXS, and have selected a Can Am model as the replacement, so I figured I had better get on board a forum somewhere. Just put in for my Guard retirement, and will be very soon looking to get into a Commander 6x6.
Wouldn't mind having the Limited with the Hvac system, but am really not sure it's worth the extra 10 grand or not. Plus it's 500 pounds heavier, and I prefer the doors off in nice weather. It's so much easier when working in the yard, and so much more fun when on the trail.
Anyway, I'm here now, so it will help me research more and make up my mind. Plus once I have it, I'll be able to share stories about it and of course, continue to learn more, as it will be my 1st sxs. Still have time before I get my retirement. Takes a good 90 days at least according to the guy I talked to... Typical government efficiency... lol.

I've searched the forum but don't think I found a solution.
I just bought a used 2022 UT 400 with only 31 miles on it. Often I have to rev the motor just a little to get it to shift into forward or reverse. The original owner told me about this and said it needed the cable adjustment that you so often read about. It also jumped out of gear a few times and did grind a little but not very often and only under heavy load like going up a steep dirt road. After reading lots of posts I figured it must be the short shifter throw so I did the shifter extension modification. It didn't help at all. I thought, should I increase the idle speed? The tach reads about 1600 rpm at idle but it doesn't sound that fast to me. It doesn't seem like cable adjustment because it clicks right in gear with just a few more revs. Any ideas?
Thanks for any wisdom.
