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!

I own a 2017 Challenger 750 and had the key way snap at the flywheel. It was removed and cleaned up and then the flywheel was put back on with a new keyway. It snapped a second time so the flywheel and keyway both were replaced. They both seem to fit nice and tight. Put it all back together and it snapped again. I have no idea why it is doing this.

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

Have a Coleman UTV 400 that cranks, runs, drives well until it gets warm and is put under load. Light throttle or full throttle it doesn't bog, but it will cut out mid throttle if you move the pedal quicker than it seems to like for example when you're getting ready to go up a hill, but if you immediately floor it, it will do just fine and not cut out. It's random if and when it's going to do it, but is consistent in that it happens only when hot/full operating temperature. I've replaced the injector twice, same with the spark plug and tried different heat ranges (NGK 7,8 and 8 iridium), replaced the fuel pump, adjusted the valves, checked air filter which is like new, changed the oil, replaced the fuel filter. No check engine light. I don't have a code reader for this. Initially I thought it might have a head or head gasket issue as when I got it, the oil was over full, very runny like water milky and it was smoking. I've changed the oil since then twice to clear and clean everything out, and it seems to be good. Coolant stays the same level and so does oil with no changes in consistency or need for adding more. Had I think 7-9 miles when I got it and now has about 77. What should I try or consider next?
