hi.
i don't know what to ask and if already was already discussed, sry. so i will tel what have and what i want.
i have a solar panel (max 18v) which charge a battery 12 v. when solar panel don't charge that because off low light i want to put it to charge a 1.2 bat.
if i use a relay the relay connect to 9v and disconnect to 4-5 and when is not connect use sane or more power than when is connect. and what is more the relay use a lot power.
is something that i can use, like when is more than 12v the electricity go on 1 pipe and when is more on another pipe.
