I don’t need temperature compensation in this application. At the highest temperature I can imagine while charging, say 110 deg F, the compensation is somewhere between .3 and .4 volts typically. At the lower end where undercharging is possible, I just don’t care.
Maybe others have larger or more sensitive loads, or are planning on charging in a very hot environment. Anyway, not much of downside to having the compensation, but I don’t want my charger in my battery box so I can see the indicators.
