Make sure BOTH batteries are the same mfg & ideally same date code. We do a whole bunch of parrallel/series strings for electric vehicle.... If you use something like the Optima YELLOW top you really do not need dual batteries. I know, duals are really cool and show you are a series off roader... but you can use just one.Sharp said:cool pics, i'm going with 2 batts in parallel each putting out 800CCA
i was just curious about the diff between power a sterio pulles vs. a winch...
On SOME DC motor's you'll see a little cap across the terminals. As the motors spin the do generate AC noise (arcing terminals). Not really needed for a winch, but tune to a weak AM radio station, then start the winch... you'll get an idea of the electrical noise.
