Hi all
Please help me because I feel I am slipping off into insanity.
I have solar panels which charge one car battery through a charge controller which keeps this battery at 13V.
I have a second car battery which is just as new or better which I wanted to trickle charge from the first battery.
So I wired the two batteries up in parallel, with one 1000 ohm resistor between the two + terminals and a conductor linking the -ve terminals.
But here is what is driving me nuts - the voltage on the second battery fell slowly from an original 12.76 V to 12.68 and falling.
How is this possible?
