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?

We have pretty much decided to buy a Polaris utv to use around the place and for some irrigation stuff. We were thinking about getting a windshield, top, and rear window. All the Polaris utv accessories are pretty pricey and I was wondering if anyone had used some after market accessories? Any other thoughts on stuff that we should put on it?
Thanks

I just bought my first Polaris yesterday and I’m waiting for it to be delivered. I opted against getting the windshield and roof from the dealer — he roughly quoted about $1k for both, which seemed a bit steep — so I’m looking around online first.
I’m specifically shopping for Polaris Ranger XP 1000 accessories like windshield, roof, and other gear. Where do you all usually buy from, and do members here get any discounts or preferred vendors?
Thanks!

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,
