Actually my graph is set to 11.7, and i ran it down to 11.2 once. Had to kick start it to charge it. I really don't like bringing it down that low, 99% of the time its in the 40-60% range when im done. 90ah or 100ah is pretty much the same ballpark for my needs. My calculations show me to run 22 hours before i am SOL.

On a Garmin your better off running a 16 to a 20volt battery, much better picture, not sure if Lowrance recommends anything over 12 volts

There's a calculator download for Excel that goes with this video. It will help you estimate run times for your graph setup with different batteries.

Even Garmin will tell you that more than 12v doesn't help performance. I'll add to it. If 16v gives you a better picture its because you have inadequate wiring causing voltage drop. Garmin along with Lorance and Humminbirds graphs processors are all internally regulated to around 5vdc. Applying more voltage only reduces the amp draw from the battery (Ohms Law). All things being equal as in amp capacity a 16v will get about 30% more run time than a 12v. Here's the other hitch, you'll need a separate charger as well.

I've been using LiTime batteries for a couple years now and no issues. I run a designated 12-volt 50 amp {basic set-up (2) 12"s and (1) 9" + FFS} for my electronics and 3 12 volt 100amph for trolling motor. Best price in town, they ship fast, and customer service is in Houston. I'm not a serious fisherman but it works well for me, I never drop below 12.1 volts. I have a very similar setup and use that same battery. Don't ever give it a thought except to charge it after each trip. However, if you think you get a clearer screen using 16 volts, they now have a 16 volt battery just for that purpose.
