Is it necessary to change the 12v battery to lithium as well? Does the converter that converts 48v to 12v have to be changed out to?

No I left it alone.

Wanted to give my info here so its documented and others know. I have had issues since day one with my Discover batteries on my Sector E1. The issue was the dealer i purchased it from was 3 hours away and both them and Hisun said i would need to bring it back to figure it out. after 3 years almost I was so tired of the low voltage errors "45C3" that i decided to replace the batteries. It was so much money and so many different stories/opinions I wasn't sure what direction to go. Last min i found Litime.com they had 51.2v 30Ah Lithium batteries. I reached out and they said they would be a direct replacement for the Discover batteries. So I ordered them. They emailed me back and as I found on the interwebs - contradicting information they said "These will not work, please deny the shipment or use for another project. The HP of your UTV is too much". Well I didn't listen and i accepted the shipment. Yesterday i took out my 8 Discover and replaced them with 4 51.2v 30Ah LiTime batteries. I installed them in parallel, I did an algorithm update on the Delta iQ 1200 using profile 233 (Closest settings to the LiTime Battery). and BOOM! it worked, and it worked like NEVER before! its so fast, two grown adults up the hill and hardly any drop, but best part at 50% charge it was showing ZERO errors. I would estimate the cart is about 2" taller now too b/c of the battery weight removed. I will update in a few weeks how they are doing. but as of now i would totally recommend and they were like $499 a battery b/c they have a sale currently taking 100 off each battery.           Hey Jamie  have you had any problems with the conversion to LiTime 4 pack 48v 30ah batteries. Did the battery BMS work well with the Delta Q charger?

I have had zero issues! I need to get the battery meter in the buggy updated to ready the battery level correctly but the Bluetooth app works perfect. I have way more range and so much faster. No low voltage errors.
