Victron 75/15 and Crown 31DC130 settings.
I have a Victron 75/15 charge controller with 200w of solar and a pair of Interstate 31TMXU which are Crown 31DC130 batteries. Here are a couple of links to literature on these Crown batteries. Cro...

Computers, flamenco dancers and 3100 people who agree with you on a forum does not begin to equal reality.
Unless ALL CELLS in a battery are bubbling slightly no solar on the face of the earth is allowing a full charge. Setting a charger to 1 amp then allowing it to charge day and night may allow a full charge with a minimum of bubbling in the cells. If the battery was never allowed to discharge very low amperages would do this over time. But that isn't reality.
Is is so easy to check for bubbling at solar day's end. And dip with a hydrometer if in doubt.
