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.

I'm having trouble finding a replacement battery for my UT400. Has anyone bought one and where did you get it? Thanks.

Hello,
Background: Bought a used 2012 700, added 2 small LED lights, wiring for a sprayer and changed front CV axles.
Had no electrical issues until recently. The old battery stopped charging so we got a new one, Rhino still wouldn't charge it.
-Started next day, drove 15-20min, then out of nowhere the check engine light came on and temp too. 4WD started to automatically engage and disengage repeatedly. Charging display started jumping all around between 11 to 13 to 15v.
-Relays, fuses, and battery connections seemed good.
-Continuity on rectifier would jump btwn OL and 00.0
-Rectifier wires from stator all read 20-21v at idle
-Rectifier diode test had 1 bad reading. So, I replaced it with a new one (but still using original plugs)
Started it up, still shows no change (12.1v idle, 12.8 with some RPM)
Also, I feel like now I maybe also smell burning plastic?
Does anyone have experience with this problem or have a recommendation of where to go next?

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?
