50ah Ionic dedicated for graphs?

Think it'd be enough? Graphs and FFS only...3 106SV's and a LVS32. I've got an extra and was thinking about putting it to use.

Might be better asked on the Garmin forum. It depends on the total draw and how long of a day is your average. Bob

thats only going to last you about 5 to 6 hours
on a 50ah you can run 1 FFS and 1 graph and stay within the 20% recommended low, you can run 2 of the graphs and FFS maybe 8 hours comfortably, longer but may be getting lower than recommended on a repeated use

Thanks! That's what I needed to know.

with a 100ah ionic I can run four units with 360 and live scope - after 8 hours I am still at about 30%. if I ever feel like I will be fishing longer I either turn units off or put in standby

If you want to try this route, this video has an excel sheet you can use to estimate and compare run times with your electronics setup. As mentioned, 50Ah is probably not what you need

Not enough, I do not like a house battery setup at all, another subject as to why,
I prefer is needed a hybrid system, AGM and Lithium connected in parallel for everything. If the wiring installation is done properly you will have interference in your MFD,s and no voltage drop.
SeaClear is not up to the task, simply it sucks

Can you help expand on why you prefer to run two batteries in parallel with different nominal voltages, internal resistances, very different cycle life, etc?

Both batteries benefit from this setup in lifespan, would be a very long post to explain this in detail. Google Hybrid battery system for boats
simple quick answer is, Lithium's do not like to be at 100% SOC, their very low resistance allows the lithium to recover fast when running and will except most of the charge current, when not running the lithium will work like a battery maintainer topping off the AGM, resulting in better life for both batteries. The AGM takes care any issue of a potential BMS shutdown that can cause damage to electrical systems on the big motor.
Just have separate batteries for testing, and should be done on a regular basis, at least yearly as all batteries should be.
Every boat that comes to me for any work gets the batteries tested always.

I run 2-9" Garmins, 1-9", Live Scope+, and a Raymarine Axium RV on a separate Lithium 12v 42ah and it was barely enough for a full day (9hrs). So I added another 12v 42ah in parallel and it easily went 2 (+a little more) days. My TM Lithium's are 12v 100ah and after 23hrs fishing, mostly on the TM, were at 68%.
