The flickering you're describing is exactly what I was experiencing before it died completely. I haven't changed any of the relays yet and curious to hear if the new fuse box relay works - please keep me posted!

I have a 2020 Sector E1. It's been a great UTV over the years and I did a lithium battery upgrade a few years back (complete game changer). Since owning the unit the dashboard and lights would occasionally flicker while driving, but not every time. I couldn't replicate the issue in any driving scenario and all fuses are good. The dashboard and several switches finally died completely this past weekend - meaning lights, winch, and dash lights do not work, but forward/reverse and speed work. I rechecked the fuses and all look good - any ideas on what else to check?

Zero issues. The E1 is a completely new and better animal with the conversion. HIGHLY recommended upgrade- especially with all the ‘how to’ instructions posted in this thread.

Great information. I did this install last night and it worked perfectly. Only thing I did different was to make my own battery cables to get the batteries configured in the best balanced configuration based upon the balanced PDF doc you provided.

Did you need to buy anything else or was this just a battery replacement and reprogram of the Delta iQ? Did the current 'charger/plug' work? Any other changes or purchases required?

Can you share a picture of the install of these batteries? What else did you need to purchase to get this setup working? Thanks for sharing the details.
