Converting from a Schott charger - wiring connector adapter needed?

There is a lot of good info from Old Houseboater in this thread:

The Delta Q has numerous different profiles, so it should definitely work, so long as the batteries aren’t damaged. The Zivan most likely would work with gel batteries on the AGM setting (86v) as gels are "charge to: at least 13.8 but less than 14.6 " (82.8v to 87.6v)
