“LO” VOLTAGE SIGN. please help!

i posted a few weeks back about a "lo 10.8" sign that pops up when i use my lights. i did replace my battery and it still does it

Does this seem like i need a new rectifier or stator?? i am no mechanic lol!!

it is a brand new atv. 2015 sportsman 570 eps (camo color) and it is very frustrating that i cant ride.

anyone have this issue?
