Is it best to stop charging once the batteries are charged

Just need to have the right charger that floats at full charge. We have a lot of lithium batteries on field instruments. They all have a solar charger on them 100% of the time. The only difference is tour field units have daily current drain.

I charge mine until they are fully charged and then un plug the charger and dont charge them until they need it again.

They should still be at 100% whenever you come back to the boat. Longest time I've tried this was about 6 weeks and they were all still at 99-100%

Once their fully charged no need to float like a lead acid. crankin battery is a flooded cell, drewcraft said this was the way to go with what I have. keeping the ionics at about 80-85% since it has been/will be a few months till I get back out on the water and just enough to keep the crankin battery topped off.

According to my electrical engineer son — “The best holding charge on a lithium battery between uses is 1/2 to 2/3 of capacity. Just charge it the day before you go fishing”
I have read this online as well so this is what I do. I have two 120 amp hour lithiums and I don’t even pull them down half way with a full day of use. I just top it off the day before I go out on the water.

Man, ditch that wet cell and get their 125a. You won't regret it.

I have Ionics in my boat running the TM and cranking/electronics. My storage facility does not offer electricity, so the batteries will go extended periods of time without a change. Recently I've taken an interest in electric powersports and started researching and writing about products that will be coming to market that are lithium battery operated. I wrote an article after a fair amount of research on lithium vs. lead acid batteries. https://chargedoutdoors.com/are-lithium-batteries-worth-the-expense-lets-find-out/

Haven't got to test them yet but hope to saturday. Pulled another 30 lbs out of the back end at least.
