Hey everyone, I’m off-grid and have plenty of spare energy, so I recently decided to lower my charge voltage to 3.45V per cell. Over the past few weeks, I’ve barely reached 60% SOC, and the batteries often sit at 100%. To reduce stress and extend lifespan, I figured lowering the full-charge voltage…

But did you drop the charged voltage in the BMS settings down from the 56.8V to 56.0V or 55.9V per my note above.

That’s it…”They” want you to fail your batteries so “They” can sell you more….Not. What a nonsensical statement. :angry:

I could answer but I won’t. Thank you for the valuable contribution to the discussion.

[image] 10:36, charging current dropped [image] DVCC dictates 2h for Absorption I’ll be back after 12:36 to see if current will drop… Very sunny day today :slight_smile:

Definitely something is wrong here. [image] I guess I’ll file for an RMA

[image] pwfarnell: OK, there is some confusion between the manuals and what is configured in the BMS. I believe that the NG manuals were edited from the older Smart battery manuals and not all data has been captured. The manuals state 13.5V float for a 12V battery and 54.0V for a 48V battery bu…

I have raised the manual issues with Victron, it is on their to do list now.

after some back and forth with my Victron distributor, we changed the settings in the BMS with Victron connect. [image] 55.5V 3% 6 minutes And this time it worked, synchronization happened a few seconds before 9:45 this morning! What I’m now monitoring is the float voltage.

Please fix my settings, 100% sync not happening
