Battery wires
 

I just purchased mike's motor mount, battery tray and a couple pinion gears to go along with my mamba monster system. I was wondering about the battery wire size. I have some 7.4 packs that I was going to run in series but they only have 14 gauge wires. Is this going to be a problem? they are 20c orions and also 20c maxamps. thanks for any help you can give me.
