Folks, read the original post. The OP has a magnum, but he is asking for someone else. The someone else does not have a Magnum, they have a converter charger. BIG difference. BIG difference.
The Magnum is an inverter also and can draw a huge amount of amps FROM the battery bank. The converter/charger does NOT draw amps from the battery bank, it only sends amps TO the battery bank. The amount of amps it sends to the battery bank is small compared to the amount an inverter can draw from the battery bank, thus the big difference.
As someone commented, a typical converter/charger can put out 60 or maybe 80 amps of CHARGING amps to the battery bank. The 12' run should be able to handle that current. 6AWG is good for at least 60 amps. 4 is good for at least 85 amps. The voltage drop over a 12' length is minimal.
