theakerstwo Posted March 30, 2009 Share Posted March 30, 2009 You would be using 4 12 volt and i would not go over 750 amp because that engine is not hard to turn.I dont think they will fit in your factory box. Unless you use car batterys. I see nothen wrong with 6 volt batterys myself.

Freightrain Posted March 31, 2009 Share Posted March 31, 2009 I put 2-12v group 31's(900 cca?) in my stock battery boxes with no problems. I have 4 total, with a 12v starter. It will wing that lil motor over for hours and not break a sweat. Start in 18* weather with NO ether. Not bad for 50 yr old diesel motor. Quote Larry 1959 B61 Liv'n Large......................

MACKS Posted March 31, 2009 Share Posted March 31, 2009 I think bigdog is talking about going from four six volt to two 12 volt for a total of two batteries,you can do that I've used just two 12 volt in my plow truck witch was an old dm and it started fine even in very cold weather,if it's a truck that you are gonna use every day your better of with four batteries,they will last longer,for a play truck you'll be fine with two.
