New batteries 4x100Ah - Charger: Quick 40Ah with 14,1v in absorption and 13,5v in float mode - BMS Smart CL 12/100 (14,2v max charge) - The charger works for about 2 hours and then goes in float mode. I tried to turn off/on the charger, but in few minutes goes back in float mode. What's wrong? Thanks2024-07-05_Mancato bilanciamento celle.pdf
Switching VictronConnect to english would be nice if you ask in an english forum :)
The problem are not the batteries it is properly the charger.
The charger needs to hold a voltage above 13.8V for a while for the balancing.
The first balancing can take a hour our two.
I'm not on a boat, I made hard copies of my cell phone (and yes, I'm Italian). The charger provides 14.1v, which is more than 13.8. Thanks, but it remains a mystery...
On your screenshots it doesn't look like that the charger is reaching more than 13.8V.
The charger needs to hold a voltage above 13.8V for 1 or 2h for the balancing.
You have a small constant discharge once the system goes into float which won't help.
Try increasing to float voltage a little.
If you can post a wiring diagram and/or a picture of the batteries/wiring it would help
