This looks like it might be a float only “battery tender”. Do you have any doc for it? In which case I would run away from it for general use.

For VRLA general purpose use like glider avionics or wing runner VRLA batteries I would look for a VRLA charger with bulk charge current ~C/10 to C/5.

VRLA I would not juice up the float voltage, those you want conservative and temperature compensated… one of the main killers of VRLA batteries is charging at too high a rate/too high a voltage/too hot…which causes gas leaking out the over pressure vents and the cells eventually drying out. There is an amazingly small amount of electrolyte in those cells to start with, just enough to dampen some thin fiber sheet spacers.

For glider avionics/motorcycle batteries the West Mountain Radio CBT battery discharge testers aka analyzers are really great. https://www.westmountainradio.com/cba.php
