I just bought a 2021 ego+ RS - battery warranty will end in 4 weeks.
How can I check SOH?
Are there recommended tests, e. g. DC charging, AC 100% charging with balancing, ...?

Charge the bike to full and do a balance cycle. Then ride the bike down and empty it all the way to 0%. Then, using a measuring device like a Kill-A-Watt meter, do a full charge again. Record how much power it used and report back.

Correct me if I am wrong but, I think Energica just extended the warranty on some of their older models battery, so you might still have a year or so warranty left on it.  But still, this is a good check to make to get an idea how it's holding up.
Also, how many miles is on it?  Typically though you'd have to put about 120k miles or more on one to really start wearing the battery hard if it has been taken care of.

@Aaron: Mileage is <5000 km 
Early Energica models had issues with battery defects, so it would be helpful to identify upcoming problems within warranty and contact manufacturer in time...

If you're concerned about that you can do the above procedure to check your battery retains roughly the same capacity in its usable portion. If it's any solace my Ribelle is a '21 (EMCE model) and I've not noticed any capacity drop after 34k km.

Due to some broken parts, I can't ride the bike. I just charged to 80% SOC.
I now tried an AC full charge, this stopped at 98% and balanced for hours.
Within an hour or so, SOC decreased to 96%.
Unplugging and plugging AC started balancing again for some minutes, then stopped again at 96% - no charge to 100%.

Do I have a battery issue?

Keep letting it balance. It may need another day or so of the BMS doing its thing.
