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!

It's not immediately obvious to me how to wire a remote control (wired or wireless) on the Sector E1. Has anyone here done this? Do you have pictures on how to get to the wiring? Thanks!

Sorry if this is on this site new to going on forums I have a 2021 hisun sector e1. I've seen people say they put lithium in can someone point me to what and how many lithium batteries to put on this bike. Thanks I notice up hill the low range says 400 amps on the dash.
