Other 12V Sources with a 24V-12V converter
Switching to a 24V battery bank has gone well so far. The 40A Victron 24V-12V converter seems to handle all my 12V loads without issue. It keeps the V at about 13.2V But a question: there can some...

Using the most widely used temperature compensation formula:
-0.005 V per C per 2 V cell
Yields at 0C (32F) -0.005(0-25)12 = 1.5V for a 24V battery. And this implies that for ideal flooded bulk charging you would need a 29.6+1.5 or 31.1V charging source.
Not that I normally camp at freezing temperatures but it may be a consideration for some.
