I have 3 in parallel also, and I connected the positive--red wire-- to the first battery and the ground--black wire--to the 3rd battery. Then I was sure to have both the charge and draw load balanced. BTW, I used 0 gauge wire since I have a high power inverter, 5000watt pure sine wave, bit of over kill, but for $380 I could not pass it up.
