I chose to recharge them fast. Why wait hours if the same can be done in minutes … just get it over with.
Incidentally, as a side note, it seems it is quite good to help the cells stay nicely in balance, this “fast recharge”, Victron in charge of it all.
Thinking further on that “complaint” of mine … so what if it was nearly 10kw?
The dishwasher would have run in any event, as would the geyser … so not saving anything by taking it scheduling/spreading those must-have loads over a longer period of time.
