Not upgraded, but I have a 93 at the helm and use a 12 for LS. Screen size is definitely a big difference. After having a 12 up front, I wouldn't ever want a 93. My 48 Amped lithium can run my 12 for 2 days with no problems. 32 should last for a very long day also. My 12 is on a Beatdown Ultimate mount and it is bulletproof! Hope this helps.
