Sizing battery interconnect cables
Hi! I am in the middle of setting up the electric system for my Ford Transit I'm converting. I am confused on sizing the interconnect cables for my battery bank and was hoping to get some help. Renogy told me to use 1awg wire but that does not seem large enough. I asked them to explain how they got that size and they cannot. I tried reading their article on sizing but came out with an incredibly low wire amp rating which again doesn't feel right. I have two 300ah lithium batteries wired in parallel. I do have a 3000w inverter as part of my set up too. Can someone explain how I should be calculating the wire size between batteries and to the busbar? I feel like I read so many different things online I have thoroughly confused myself. Appreciate the help!
