I tried to help him, but he is a very stubborn guy !! I told him Id ask the experts.He is running 3 batteries, 1 Interstate true Cranking battery (800 or850 CCA) and 2 Interstate group 27 deep cycle TM batteries. (Pantera III with 200 Pro XS with a 36v Motor Guide)In 2 tournaments, his boat would not start after fishing and not cranking the engine for approx. 5 hrsMy advise — poor set-up as a true cranking battery has no place in that setup and to run 4 batteries if he wants a 36 v system , or get 3 group 31 dual purpose batteries to try and support that load.His Plan– get 1 dual purpose battery goup 31 as the cranker (likd a Sears PM1) and leave the to TM batteries and run it like thatMy guess– not long before disaster strikes again Any comments or suggestions appreciated. Thanks, Oh, did I mention hes on the tight side!!

Heres my opinion and its different from some of the others. Unless you dont fish much, dont fish in wind or current, or dont use the trolling motor much then youre OK using the 3 battery 36v system. If you do, then I recommend using 4 batteries. If you dont want the 4th battery, then the best set up is what you advise. However, his plan will likely work too and he will have weak batteries again sooner or later with the troller. Your statement “not long before disaster strikes”………………….that can and will happen with any battery set up!I would have never had issues in two tournaments. I would have changed all 3 after the first battery issue!

Thanks,I agree Phil, batteries are the life of the boat , one thing you just cant scrimp on IMO.We lost 2 1/2 hrs of fishing time and probably would have finished a little higher in the money last weekend if he would have fixed the problem. Lucky we were able to get back in at all !! Guess I will demand we fish in my boat next time!!!

3 batteries are fine, thugh not with that cranking battery. He should invest in the best possible battery for his cranking battery and we suggest the Sears PM 31 for most. Just because you can get them easily. Trojans and other AGM 31 batteries are great , though hard to find easily. His plan is sound and will resolve his issue.

Parenting 101…..let him fail. Help him later after he learns a little from his own experience…

I have been running a 3 battery setup for years with 31 series Optimas on my 01 P3 and have had no problems even on windy days, the OI was a great recent example as I was on main lake points for both days pitching to boulders and the troller stayed on about 75% the whole time.

Im glad to know the 3 battery system will work, thanks.I do wonder though, if the group 31 will fail prematurely when its tied in with 2 group 27s in his set-up.Thanks again for your input.

I run a Trojan SCS 225 (31 series) for my cranker, 36v troller, and asscs and run two Trojan SCS 200s (27 series) for the balance of the 36v troller needs……NO PROBLEMS!However, I have an old school Yamaha 200 VMax to turn over, not an HPDI or Opti Max.The batteries were purchased in 2007 and still going strong.
