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?

Trying to get running a 550 Colman running but I think head gasket went bad. Do i just replace with new gasket, clean up and replace or is there more to it?

Honest question for experienced riders - how much of a real problem is losing cell signal on the trail?
Context: I'm coming from the overlanding world where staying connected is a big deal (long multi-day trips, remote locations, solo travel). I invested in a cellular booster for my truck (around $400) and it's been worth every penny for both safety and convenience.
Now getting into UTVs and trying to figure out if this is even a relevant concern, or if I'm bringing truck-camping mindset to a completely different activity.
Specifically:
In your experience, is cell coverage while riding a "nice to have" or a "need to have"? Do you actively try to maintain connectivity, or is "going off-grid" part of the appeal? For those who've spent money on connectivity solutions, what did you end up with and was it worth it? I'm seeing some cellular boosters marketed for vehicles in that price range, but almost zero discussion in UTV forums. Either it's not a real problem for most riders, or there's something about UTVs that makes traditional boosters impractical.
For those who ride in legitimately remote areas - what's your actual setup? Just curious if I'm overthinking this or if there's a real gap here.

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?
