They show an operating temp up to 50C. It’s hard to tell with the Engrish translation, but since that sentence is in the context of the temperature compensation chart down below, maybe they just don’t want us to go any lower than 53V.
In other words, I was reading it this morning as “disable temperature compensation”, but maybe they just mean “this is the lowest your charger voltage should go”. As another tidbit: They also later in the manual say that high operating temperature cuts battery life span in half for every 10 degrees above 25C. If anyone needed to make a case to their finance people for air conditioning a comparison to changing batteries twice as often might do the trick.

Perhaps above 40C the run away problem levels out. Or maybe that is outside the maximum operational temp of the battery?

Hopefully we never get that room up to 40C/105F, but why would we turn temperature compensation off at that temperature? _____ -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com
