Default Battery to Battery charger/stock alternator in 2011 Suburban 1500
Hi everyone, I'm installing a battery to battery (DC/DC) charger in a 2011 Suburban 1500 to charge the house bank in a trailer. Trying to find the output in amps of an oem alternator and how much the vehicle systems use in normal operation. Can anyone help with this info? Thanks in advance if so, I tried checking the upfitter's guide and it's a lot to decode, and I'm cruising the forums to no avail. Trying to figure out how many amps (20A, 30A or 60A) I can pull without overworking the alternator.

Thanks,

Ben
