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!

QUESTION: How to wire the C/B into this current dual battery set up.
EXISTING SITUATION: MAIN Battery is OEM and feeds OEM circuits. Added an AUX Battery in the OEM dual battery location. Connected the AUX - terminal to the MAIN - terminal. Connected the 100A Accessory Fuse Block power cable to the AUX + terminal. Installed a smart isolator between AUX and MAIN batteries where a cable from AUX + goes to the isolator and a cable from isolator to MAIN battery + terminal. Installed separate QD battery tender cables to both AUX and MAIN batteries + and -. The dual battery system appears to work as intended. For this Phase 1 improvement, to avoid having to constantly pull the leads on the AUX + battery post off and put on, for testing or maintenance of Accessory circuits, I wanted a more convenient and safer way to open the circuit from the AUX battery + terminal the Accessory Fuse Block. I called an off road dealership and was told to install a much larger capacity circuit breaker than the 100A rated Fuse Block and was recommended to get a 250A C/B like the one in the pic, which I did. I was told the reason for the C/B high amp rating was two-fold (a) to trip in the event of a battery short circuit and (b) to be able to conveniently open the C/B to kill power to the Accessory Fuse Block without removing leads from the AUX + terminal. The 250A C/B has two posts labelled "BAT LOAD" and "BAT LINE". There are currently three connections to the AUX + post: (1) Accessory Fuse Block power cable, (2) cable to Isolator AUX in terminal, (3) cable from AUX battery charger.

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..

While adjusting my suspension, I noticed an unused two wire connector on each side just hanging loose. Anyone know what they are? Nothing in the manual about them.

In the market for side by side. Narrowed it down between the pioneer 1000 or defender Hd9. Looking for pros and cons of both. Any info would be helpful in my selection process. Noise, speed, reliability, ride, all of it.
