Battery tender plus hook up question
Trailer in sig has two 12 volts in parallel. I just bought a battery tender plus to hook up for the winter. May be a dumb question, but where is the best place to connect? Not really any instructions...

One battery hookup would be fine, but the very best way is the negative on one and the positive on the other. This will compensate for the tiny amount of resistance between the batteries.
