Hi! I got this solar battery charger circuit from the internet..
It says that the ciruit can :
-Charges until Vbat = 13,8V (adjustable), then float charges;
-Shuts down load when Vbat < 11V (adjustable), resets at 12,5V;
-Temperature compensation;
-Will work with cheap and readily available components like LM393 comparators and BUZ11 FETs;
-Uses less than 1.3mA (Attempts to use micropower comparators have failed spectacularly so far, see below);
-Burns less than 20mW in FETs when charging at 0,5A. (More expensive FETs with a lower RDSON will yield even better results).
Hope u guys can comment on it before i start building it(whether its okay or not)
