We've completed an electric conversion on our catamaran and have two ePropulsion E163 batteries, one dedicated to each engine. I've also installed two 600 Watt solar array (3 200W panels in series) to a two Victron 150/45 MPPT controller to charge each battery.
This is the data sheet for the E163 battery:

What are the correct settings for the Victron MPPT to most effective charge this battery?
I'm presuming that the Lithium - User Defined - Advanced Settings On is the right place to start.
Here is what I have right now:
Battery Voltage: 48V
Max Charge Current: 30A (based on AWG10 wire connecting the MPPT to the battery)
Charger enabled (On)
Battery Preset: User Defined
Expert mode (on)
Absorption voltage: 57.6V
Float voltage: 54V
Equalization voltage: disabled
Re-bulk voltage offset: 0.40V
Absorption duration: fixed
Absorption time: 2h0m
Tail current: disabled
Equalization current percentage: 0%
Automatic equalization: Disabled
Equalization stop mode: Fixed time
Equalization duration: 2h0m
Temperature compensation: disabled
Low temperature cutoff: 5 degrees C
Ideally, I'd like the solar panel to maintain the max possible charge until the battery was fully charged, perhaps tapering the charge to no less than 4 amps as it got above 90%, and then cut charging off completely when full.
Thoughts?
