Fun with solar and Renogy MPPT 30 Li (kind of)

Gel mode on Renogy MPPT has Bulk ending at 14.2V and then it would go into Absorption for 2 hours.

The battery is resting now at 12.8V, goes up to 12.9 when DC supply or solar is connected, and it shows the same "demand effect" in Gel mode as it does in Li mode. It reads 86-89% in either mode. According to battery manual 12.9V under charging is only ~20% SOC: https://www.lynaclithium.com/wp-content/uploads/2020/10/12.8V-100Ah-True-Series-Quick-Sheet.pdf
