how many optima batterys for a oasis compressor

i was just wondering how many optima batters,yellow top would 1 be enough or would i need 2, please help

come on yall i just bougt a oasis hp1000 i need some please

I run 1 redtop. So far 2 years and no problems

i run the xd2000 on my one blue top and don't have any problems

How do you guys have them wired up? Is the battery located near the oasis? Im guessing single battery mounted next to the compressor with a large gauge power wire running to the stock battery. I was thinking about installing one for a customer. He already has dual alternators.
