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!

The conversion took about 350lbs. off the vehicle. It never rode great, but now I feel every crack in the road. I have backed off spring compression nut to the point just under where they would move around if suspension was at full extension, but it is still very stiff. I would like to put some softer coilover springs on it, but I have no idea what the spring rate is with the original springs so I would just be guessing on what to order. Does anyone have the data for the original spring compression rate? I am willing to give up a little ground clearance for a softer ride. Right now when sitting still the rear suspension is at or near full extension and the rear tires have several degrees of camber which will cause uneven wear if allowed to continue in this state.

Top speed is 30mph on flat grass ground. but it will not go up minor hills forward or reverse without a runing start. If you start at the bottom of the hill machine will stop about 1/2 way up. I have the engine cover off and you can see the outside of the drive clutch will stop spining., and the engine does bogg down some. Dosent matter if engine is cold or warmed up. Seat belts are connected. Fuel is clean
I am the 5th shop to look at it and different shops have replaced the fuel pump, injector, ign coil, wet clutch,
I am not sure how to check for codes with this machine, can anyone teall me how to do it?
Compression with hot eng is 145, valves adjusted to .005 with a cold engine. Dash shows 426 hours
I am not convinced it's an engine problem

Recently I had an overheating issue on my 2022 Coleman Outfitter 550 (Hisun UT550) and to check to make sure it was fixed I took it out for a ride around the block. After a couple cycles on the LED coolant meter, I took it for a couple mile ride and on my way back I heard a loud metallic snap then a grinding noise. It was still able to move under its own power but very slowly. I was about 2 blocks from the truck so 'I limped it home and up onto the trailer. I know I need to tear it apart and look for what broke, but anyone have a guess as to where to start? I'm seriously getting tired of this damn machine! 750 miles on it and already replaced the belt, wet clutch, primary clutch, clutch roller weights among a few other things. Seriously, this friggin machine has spent more time on the lift than on the road. I thought I bought this new because it was from the owner of a tractor supply, but he registered it under the stores name making me the 2nd owner voiding any and all warranties.
Any Ideas what to look for would be appreciated.
Thanks

Spent today at a Honda dealership looking at their 520 side by side, then on the way home past our Lowes noticed they had several new UTVs on site, so we U-turned and ducked in there. We were impressed that all that came for $9,999 metal whole length skid plate, nice sized bed, roof, windshield, side mirrors, winch, upgrade looking tires… all of which would have added thousands of dollars to an already expensive Honda 520. Now Honda does have a great reputation from my trusted UTV experienced buddy, so it has that going for it.
