Wiring a Winch — backup battery?

Hi guys I have a 2003 Sportsman 600 and I got a 2500LB Badlands winch for it. I got my front end all apart and have got it mounted now I’m ready to wire it up.

Two questions:

1) is there a detailed guide around? I have read enough to feel OK to attempt it but it seems like this must have been done so many times that there would be some clear guidance for it.

2) does anyone ever wire up a second battery (winch to be used with a plow)?
a guy a few roads over I see his ATV with a big car battery on the front rack, he said he had wired the winch to that battery and then that battery basically to the alternator so that he says it charges the secondary battery while he’s plowing. I assume he did this to reduce the chances of the ATV not starting a day after heavy winch use and the battery levels are low. I have a powersport battery on my motorcycle i could take off and use for the winter if anyone thinks it’s wise?

Thanks guys
