I installed a new optima under the drivers seat...it is 65 amp hrs.,
which i suspet is much more than my starting battery under the passenger
seat.

When I installed the aux battery, I RAN a wire from the #30 post of the
relay under the seat to the positive terminal of the battery so that the
aux battery would charge while driving.

I also hooked up a 1.5 amp trickle charger to the aux battery only

I also had a solar charger already installed which i unhooked from the
starter battery and connected to the aux battery

My question:  I am concerned that when i am driving, the main battery
under the pass. seat will come to full charge before the aux battery,
since the aux battery is 65 amp hours and thus will take more time to
charge....and it will also be more depleted  .... with the result being
that either the main batttery will get over charged or the aux battery
will get under charged.  I suspect there is an easy solution to this,
but i need help.

I would also like the trickle charger to charge both batteries, but
again the above concerns.

Thanks for any help tha can be rendered
