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 just bought an older (2008) Teryx 750 and am having some concerns. Hoping of course, that most are not too big. . . but more knowledgeable folks like yourselves will surely have some ideas. Thanks in advance.
-- about 2700 hrs, camo version
-- Starting: after not running much at the auction site, I tried it and it was tough to start but half of this was likely I did not quite know the tricks for how long to keep the choke on. However, once it started it was kind of hard to keep running until it warmed up(once warmed it starts perfectly every time with no choke). Now, back to running after the first ignition: I had to hold the RPM's up a bit to keep it running and when doing so it sounded as if a little gnome was inside the engine pounding on something at random intervals. Wondering if this could be detonation-- "knocking"? After warming, it disappeared completely. Maybe just need higher octane gas??
-- After starting and running a bit there was a pretty terrible smell, most "like" burning rubber or an electrical fire. No fire or resolution of this. Eventually this TOO went mostly away, but still basically present. Could it be adjustment needed for the main belt variable speed tranny?
-- When I move from neutral into either Lo or HIGH range forward gears, I get gear clashing. I did NOT put foot on brake and read in manual(just NOW) that you are supposed to do so. (I have NOT gotten back out to check and see if this matters. ) OR, could it be part of the drive system is mashed up??! Geez, hope not.
-- There is a big open hole allowing direct sight into the belt transmission on the back right side. This can't be normal, it must require some plastic cover. Right? Any rodent could get right into the transmission!
-- THere appears to be no muffler or spark arrestor unit. This "could " be the cause of some of the smell. . . ?? but that should not smell like burning rubber or electrical smell. . .
SO. That is all.
I sure would appreciate any insight on this issues and finally(!). . . if I was to take this into a local dealer what would you say are the top three issues I should have them address first?
thanks!

We've had the Predator 459cc on our American Landmaster TW450 for about one month now. And I've got to say, this has been a solid motor! My kids have really put the motor and the whole side-by-side to the test. But it's running great! The original motor was a Kohler ECH440 with 14hp.
We've had ice and snow all weekend. But we can feel the extra power with the Predator 459cc (15.8hp). Just wanted to let y'all know, if you're looking for something to replace your motor on the TW450... We considered the cheaper Predator 420. But I'm really glad we got the 459!

We've got the old Kohler motor out and the new Predator 459cc in!
But before we put the motor in there. I took some pics of the old wires. I'm hoping y'all can help me figure out what all these are for and what we need to keep.
There are a lot of inline fuses. And all the labels we can read say "12v pos" or "regulator/rectifier."
Main thing I'm looking for:
1. Wires to connect the stock ignition to the starter on the new motor
2. Wires for the headlights
If anyone can help me identify what all these wires are for, I'd appreciate the help!
