ionic 125 for graphs will still give you fuzzy picture towards the end of the day due to lower voltage if you run 4 graphs (it would show that it still was 40-60% charged but my volts would go on my garmin from 13.2 to 12.9 and it would destort the picture.) I went 100 amp hour 16 volt from power house lithium for all 4 graphs, livescope and 360 and it solved all my problems. If you're getting distortion at 12.9vdc then you have some questionable wiring or connections. All manufacturers graphs are internally regulated to around 6vdc. A higher voltage battery will overcome crappy wiring though.

I know we disagree about this everytime I post my set up but I am telling you i have seen this multiple times on multiple rigs with good wiring. im not going to argue with you.

I’ve had my Ionic 3 years now and never noticed that cranking my SHO in the cold.
Must be a Merc thing. My SHO fires off quick I do think it’s a Mercury proXS 2 stroke thing. I haven’t noticed any distortion on my Garmin, but I’m only running 1 now so it might be possible, I mostly have lowrances and they seem to stay the same throughout the day. Barrett, you have 12’s or 16’s? MinnerB, have you noticed this situation on that sexy Skeeter?

Not arguing with you at all. I have Sea Clear harnesses as well. Something I found when upgrading all my graphs this past spring is the connectors on the Sea Clear were oxidized really bad. Discovered it when pulling the old power cables off that go to it from the graphs. I didn't have a problem before hand with old graphs but did clean them up really good with a wire brush before installing new power cables.

Barrett, you have 12’s or 16’s? MinnerB, have you noticed this situation on that sexy Skeeter? I have an AGM dedicated for cranking only. The 125 Ionic runs all electronics/lights/pumps. I will say since it’s not connected to motor and doesn’t get the alternator top offs while running, it gets into the %30s after 9 hours. I think am 11 hour day would kill it! On my old boat with the AGM X2, I saw voltage drop to high 11s and no change with LS clarity. As far as cranking, my other old boat that had a merc 2 stroke required a high cranking amp battery as recommended by Merc.

The SHO cranked slow then for sure. I used to carry a jump box just in case.

Yeah I always carry jumper cables and the X2 made me use them more than a few times.

I've noticed my Ionic 125 go down to 12.9 at the end of the day, but I've never seen a difference in my Active Target. I don't think I've ever ran it below 50% in a full day with some running.

Minner, do you see the Garmins start to go a bit fuzzy when the battery starts to get low?

I have an Ionic 125 AH on my 225 Pro XS (2 stroke) #1B243409 and i'm not getting that good snap the Pro XS should be giving at start up. Battery is running a Garmin/GLS10, Helix 12 and Helix 10. Battery is in good health and is charging normal and not over loaded. My dealer states to use a AGM or Lead with the correct cranking amps. Same motor and battery, my ionic was “snappy” up until it got cold. My lead acid was always weaker sounding than the ionic. I think it was in the 40’s last time out and i didn’t think the ionic was going to fire the motor off, got better once it warmed up during the day. I have wondered if it’s something in my motor or thickening of the oil residue in the cylinders. Interesting that you are experiencing the same thing. I have the ionic and a big lead acid (napa7234) on a battery selector switch, so it’s easy for me to compare the start up of each. I’ve had my Ionic 3 years now and never noticed that cranking my SHO in the cold. Must be a Merc thing. My SHO fires off quick I also believe it's a Merc Pro XS 2 stroke deal. On the BBC it's not recommended for engine over 150 pro xs as i read it. I could be wrong. I've put a 31 XHD Interstate on will see how it responds.

Lithium batteries can be a bit sluggish when cold. Once a few amps are drawn to heat it up then they perform better. As for cranking the motor first thing on a cold morning the SHO only requires 500 cca where as the 2 stroke Pro XS minimal recommended is 800 cca. Even though the motor has less displacement and lower compression that compressor takes a lot to spin over. Some say to turn all your graphs and lights on when you pull up to the ramp and get your boat ready helps warm the battery up and crank better.

I’ve got an Ionics 125 it powers two 12s a 9 and livescope. SHO motor has bust right off every time. I’ve never got below 70 percent on a single day of fishing when fully charged. Sea clear harness as well usually start the day with 13.4 volts never seen it below 13.1. I did just read an article that keeping your batteries at or below 80% charged is the “comfort zone” for lithium battery cells. Im doing this as best I can to see what kind of life I can get out of them. I’ve had this set up for 3 years and love it.

Wet cell for starting (wally world battery), dedicated 100ah lithium for electronics, two 100ah lithium's for the TM. I would ask a experienced marine engine mechanic and see what they say. They know what you should be using, and what you should stay away from.

It will change on a Garmin. Launch a jerk bait at 70 feet and see what it looks like compared to when you started the morning. Maybe its just a Garmin thing. The thing about ionics ( I have 3 50 AH trolling motor and a 125 now overkill for cranking, live well, gauges and lights etc) is why at 60 percent does a 125 AH battery start losing volts?
