All;
While there's a thread about re-inventing the house bank here, what about new battery technology for starting banks?
I'm trolling for comments on using 16V racing batteries for the starboard starting bank.
A few battery sales folk who love selling me 4D 8V batts are suggesting I try them out... They're a ton easier to manage than the 100 lb. 4d's. and I'll save space in the battery boxes.
If anything I'll have to build up some blocking to keep them where I put them if we go this way.
He also suggests going with four them them... two in series, paralleled with another series set.
Comments please? Has anyone done this? Important fact: 32V starting and house banks on Chartmaker.
This is the starboard bank which is starting only. Dave Wigler on here speaks favorably about using the golf cart batts too... but when i discovered the 16V racing batteries as an option, it sort of turned me around on new possibilities.
Thanks.

Re: New Starting Bank 8V71Ti
How do the specs compare to the current bank? Do you have a link to the specs?

Re: New Starting Bank 8V71Ti
What CCA is required for an 8V71TI?

Re: New Starting Bank 8V71Ti
Yeah, I was about to say. 8v195's are only rated at 980 CCA. And they are hooked up in series, so the amps are still 980. But that makes sense now, 1900 at 12v.
The 16v racing batteries should actually work, 4 of them at least, in series and in parallel. And they only weigh ~40 lbs each. And have a 12v tap. Longevity though?Prometheus

And if they're AGM, good luck finding a 32v charger to charge AGM. They won't last long if you use the lead/acid charge profile.

Re: New Starting Bank 8V71Ti
Just buy the OEM Rolls 8v batts and be done with it for the next 10-13years. You'll save money in the long run. But what do I know?
I know nothing. I'm not an electrical engineer. So, I just go with what the original engineers did. And that seems to work great.Sky Cheney
