Hello, All! I've decided to replace the traction batteries in my 2018 Sector E1 with a 48V Lithium set. They may be expensive, but I figure the Discovery Dry Cell are, too. I am not looking for the max driving range, as I have never received near the brochured range to begin with, but a good mix of charge/ get work done/ charge is what I am expecting.
I have settled on the 48V EAGL kit from bigbattery dot com. Each battery pack provides 30Ah. The kit ships with a charger, as well. The packs would be physically connected in parallel (using a busbar) to one another, maintaining the 48V voltage, but together would be able to provide the amp draw the buggy pulls when going up hill or towing a rake (rated 320 max continuous Amps). This is in comparison to the serial connection the eight 6V lead batteries. Each of the EAGL batteries looks to have its own BMS; am I correct in thinking I will have to use their included charger rather than (simply) changing the onboard charger to lithium mode? The chemistry of the pack is LiFe PO4, for what it's worth. I haven't torn anything apart yet (to diagram), so I am not sure how the dash will interpret the AMP draw, but the kit I am looking at includes a dash mounted charge indicator.
If anyone has completed a similar conversion, do you have any tips? Specifically, how did you remove the original batteries, and how did you secure the new ones? I am guessing that almost any change from the stock batteries would involve at least some modifications. Any tips would be appreciated, especially things I may have failed to consider. Thanks!

When we first heard the noise, we immediately stopped driving it...at first we thought it might be a linkage issue, but after further inspection looks like the sound/jolting is coming from the rear diff. Took a video below...
Anyone know what is creating the diff to skip/jump like this? We drained the diff oil and didn't look terrible, no metal.
Other info that may be useful:
1400 miles on it
Recently tightened the E brake
P.s. never posted on this forum before, let me know if the video does not work

Apparently, these are Hisun or at least they use Hisun engines. I can't find much info on them online yet. Ran across a used one with just 100 miles on it as a very reasonable price. Just curious.
Okay, more info...they are owned by Textron Corp who also owns Bell Helicopter, Cessna & Beechcraft aircraft, Ez-Go & Cushman and Arctic Cat and a bunch of other companies.
So are thy cheap Chinese crap machines or are they good to go?

just an update on my MSU 500 . For all the misery it caused me the first 2 yrs, and the combination of some quality YAMAHA parts, it has now become a reliable ,useful UTV without the constant fear of having to push or tow it back from trails. I have not had a single issue pop up in a very long time.. FINALLY!....and as a side note, I just bought a C FORCE 600 ATV to replace an old and well used Honda that finally after 18 yrs gave up a rod bearing. So far the new one has really impressed me .. I like the new Power Steering and this CVT Auto Trans is new to me on an ATV .. I m used to constant shifting on my Hondas . It also has something I have never seen. Its EBS engine brake system, as soon as you let go of throttle, it engine brakes you to a stop rather quickly.. its great idea for the grandkids safety . Takes a little getting used to tho.. All in all, I like it. We shall see how durable it is after break-in.. I do "RIDE" them! .....and they honor their warrenty! and the dealer is 15 minutes away..
