Default 1976 K20 winch problems.

Hope everyone had a safe holidays! I put a 12K pound winch on my 1976 K20 bonanza with a 55A alternator. The problem Is the winch drains my battery damn near dead within 2 minutes(65A draw no load 380A draw at 12K load) . So I want to put dual 1000CCa batteries with a 105 A alternator. I did read V belts have there limitations but I see 250A alts for sale so if anyone has had experience with this kinda be curious on what actually works!

Yeah 55A Alternator aintgonna cut it. What I had my Jeep CJ-5 I had an 8000 lb Warn on it with the 115 amp alternator. You want THICK power cables, short as possible and a high performance battery. I guess you could run two alternators but frankly I think its a waste of money and time. Then again yours is a 12,000 pound unit so it might work.

Dual alternator might end up being the best with tho identical units I just don't know how much a V belt can even take
