Liontron charging incorrectly

[nanno.schering (Nanno)]

I have a similar, but less serious problem.

I use a mppt 75/10 with a Liontron lithium battery. It stops bulk loading early at 80% and starts floating at 85%. I tried to set the absorption voltage 0.2volt higher to no effect. The battery voltage is then still lower then the absorption voltage set. Has anyone any suggestions?

Moved to a different topic as this is a separate issue.

You are assuming that SOC is correct, often not the case on unsupported batteries.

Suggest you do some searching on this battery manufacturer on this forum and the archive.
