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!

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.

Hey there,
I’m trying to find a CVT (variator) for my Tracker Off Road 800SX Crew. Do you happen to have one, or know where I can get it?
Also, if you’ve got any other parts for this model, I’d love to hear about them!
Thanks a lot!

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.
