Yep. Nearly impossible to make something work on the full voltage range might it might see in boat or vehicle use. The easy solution is to regulate the voltage down to something lower than you’d ever see in normal conditions so the unit works the same over the entire range.Originally Posted by cards21

nothing else matters.
All major brands can safely run 17 volts or more. Lowrance is the lowest at 17. Garmin 24 plus and bird I believe right around 20
One would expect a 16V LiFePO4 battery would be charged at 17.5 or 18V. One would either need a regulator to protect the unit when charging or to disconnect it prior to charging.

I could use "more power Scotty". I have space to add an electronics only lithium but my question is if I just replaced the AGM starting battery with a lithium do I need to replace my 3 bank Pro Charger or add a single bank for the lithium? Same question would apply if I just added a lithium as a fourth battery
FWIW. I'm using a 16V Amped Outdoor battery in forward storage that is running one 106 and LVS. I can fish it for 10hrs and it never drops below 15.2V. The AGM starting battery runs everything else (2 106's, 1 HDS, 2 Talons, Livewell, drive motor on the LVS power pole and starting). That battery will easily drop down to 11-11.5V within a few hours of fishing so I have to start the big motor to keep it up in order to make a full day. This battery has been replaced twice in the four years I've owned the boat. Probably due to the degradation of low voltage operation mentioned by haus93

Easiest route is to change to a Lithium Starting Battery, I would check out our new 12v-100Ah All Purpose Lithium. PM sent
I went with the Powerhouse regulator they offer because Lowrance caps at 17V. My AT image really suffered when my volts would drop. It isn't an issue anymore.
we sell a regulator that limits the voltage to 16.2 and recommend this if using one of our 16 volts with lowrance units
we could set you up mwith one of our run and gun charger s for your 16 volts and utalize your current charger nothing else to plug in or you could go with a stanfd alone charger that you would plug in when you get home. contact me happy to go over options with you based on your current setup
My set up now is a pair of 36V 40AH for the TM and the 16V for the electronics. I have run and guns for both the 16 and the pair of 36s, so my alternator shares the charge to the 16V and 36s after the AGM is over 80% (don't quote me). Additionally, my 4-bank dual pro charges all 4 batteries when I plug it in (running through the run and guns). It's a sweet set up Powerhouse offers. Not cheap, but sweet.
yes you have that exactly correct. Thats one of our most sold setups. For what you have there not really that badly priced , super solid setup .My set up now is a pair of 36V 40AH for the TM and the 16V for the electronics. I have run and guns for both the 16 and the pair of 36s, so my alternator shares the charge to the 16V and 36s after the AGM is over 80% (don't quote me).

Agree Catfan, Just received confirmation from the Garmin Engineers that the voltage on Echomap, GPSmap and Livescope units is internally regulated, so putting more voltage in does not correlate to getting more performance out. Additionally what most consumers don't understand is that PPI (Pixels Per Inch) is SET in the units hardware and nothing can increase them, including voltage. A units resolution is fixed.
The reason most customer see image gains when using our 12v or 16v battery as a dedicated supply is due to finally installing a dedicated harness which eliminates all the items in a boat that can create voltage losses
I would be glad to discuss with anyone needing help
If I understand all this correctly... and I think I do... users will not see any change in image quality, neither an improvement nor loss, as long as the voltage that is delivered to the unit is within the voltage range of that unit. Image quality stays the same until voltage drops below the threshold where it can be regulated up and at that point the unit would turn off. This is of course only with respect to voltage as noise or interference can cause image quality issues separate from voltage level.
I do want to add that our sponsors here do a great job with battery info and help. I am also not anti-lithium. They absolutely have great energy density and will keep your electronics running longer.
For you guys running out of power on your trips, you should look to the sponsors on this thread for the right lithium setup.

Can you run a lithium parallel to agm or is do you just not run then parallel and it will be ok?
Look into the Bandit. I recently added a 12" solix and mega 360. I elected to tap into my 36V at the bow and hook to the bandit and then power up my 12 and 360 from it. I get constant 14.1V and no interference.

1. please do resurrect 2 year old posts and no you can not parallel a lithium and agm
I see around 19v plus charging the 16v batteries in my car. So be sure the marine electronics are designed for this as catfan is saying. Cj
