Epever BN4215 and CALB Lithium lifepo4

[Redmondt]

Hello friends,

want to connect a 100ah lifepo4 CALB battery with my epever bn 4215 mppt controller.
Anyone know, what parameters I need to type with the MT50?
I found some for the Battleborns, could I just use them also for my calbs?

Also; what do I exactly need to set, if the 100ah battery should only be charged until 75%? Battery capacity to 75ah?

Thankyouthankyouthankyou

I'm new as well but I'm pretty sure you want to get more than 75% in to those cells. I have read that repeatedly undercharging can lead to premature voltage rise which can trick charging sources in to thinking that the cells are full when they are not. It's a type of memory effect, but one that is reversible if the charging regime is changed.

And i thought thats exactly what I want.
If you dont charge them complete full, u increase the lifetime extremly!?
