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!

New to the forum. New to UTVs. New to Electric motors. I just got a 2021 Hisun Sector E to help with moving stuff on my steep 5 acre wooded mountain patch. Plus I thought it would be fun on the gravel roads in the "neighborhood". Because we are remote and part time to the property, I didn't want the hassle of dumping out old gas or messing with oil and filters and all the usual maintenance of a ICE. But the biggest reason for me was the noise. I test drove the Axis utvs at Tractor Supply Co and they were LOUD. Seemed to ride rough too. If you want quiet, then electric is the way to go. But it does come with a high price tag. And all the electric models are still in their infancy. So its a bit of a gamble too. I bought the property for quiet. I wanted to keep it quiet. I liked that the Hisun had the dry cell batteries so there is no maintenance of checking and adding water. I'm a little worried about their lifespan especially after one person's poor utube review about them. But the dealer said the company took that to heart so hopefully changes were made for better batteries. There were no Lithium battery options available anywhere near me. Polaris is supposed to have one later this year. I liked that the Hisun came standard with roof, windshield, winch and trailer hitch. I have had the sector for only one day and worked it and road it good. So far I have a big smile on my face. I wish there was a category for this model on the forum here. Meanwhile, maybe folks will share their insights/ experiences on this thread. I'd like to learn as much about the sector e as I can. There isn't much info in the owners manual.

Interesting experience coming down the hill today, as something in the steering rack seems to have sheared off. It works partially, and at low speed, but is basically gubbed. Finding parts in the UK is an utter pain - there doesn't seem to be any good independent suppliers. I guess I'll have to go to the dealer, pay a small fortune and wait a year for it to arrive. Between this, worn out suspension bushes and the ongoing battery issues, my initial enthusiasm for the machine is beginning to wear thin.
