12 volt 105ah eve charge settings

[Roeltwee]

Hello I want to introduce myself I am Roel 26 years old from the Netherlands. I am an elektrician and in the summer.

I am camping on an off grid camping. I just started the build of 4s105ah 12volt lifepo4 pack bought from docan power. I am in the process of top balancing right know. This pack is for a friend of my to replace his old lead acid battery. He has a victron mppt 100/20. He is only camping in the weekends and the battery is topped of most of the time. And my question is what is the best charging settings to keep the battery around 80 or 90 procent? Because I think it isn't good to Koop them around 95 or 100%?

I hope someone can help my!

You should bulk charge them at 14.6v until 100% then float charge them at 13.6v.

To get 80% 90% range charge at 13.7 to 13.8 with a short absorption maybe 5 to 20 minutes. Float at 13.2 13.3 is fine.
No need to press the cells to the max.
