Last summer I install a Victron SmartSolar MPPT 75/15 (S/N HQ1942VPY9) in my Airstream travel trailer. This spring I update it to the Version 1.59 firmware.
After this firmware process, the new “default” Setting parameter become to “Gel Victron discharge (2)”.
Prior to this firmware update, the “Battery Preset” was set to “Customize” with my specific parameters in accordance to Flooded Deep Discharge battery..
The battery type in my travel trailer is a pair of 12 Volts Group 24 “Flooded Deep Discharge”. North American manufacturers mostly use this battery type in the Recreational Vehicle industry.
With this new firmware, in the “Battery Presets” choices are “AGM Spiral” and “Gel type” batteries. And the Customized battery charge parameters the choices are “Gel”; “Lithium” and “PzS plate traction 1-2and 3”.
I am aware that AGM and “Flooded Deep Discharge” batteries have similar charging parameters exception to the “Boost” phase voltage setting.
With this V1.59 Firmware version what is your recommendation for my “Flooded Deep Discharge” batteries.
