I used the information at http://www.interstatebatteries.com/cs_eStore/content/product_info/marine_f.aspand the calculator at http://www.evdl.org/uve/battery.html to come up with a peukert exponent of 1.2565 and a 100A (worst case, I hope!) ~30 minute discharge time. Golf cart batteries are big. I'd have to figure out whether I could even fit them on this platform. I don't think I could fit 8 6V golf cart batteries. The 12V golf cart batteries I've seen are all too big to fit; the group 27 size are a tight squeeze, and say a set of four Trojan T-1260 I don't think I can find a way to fit. 6 8V T875 would have more runtime than I need and I haven't figured out how I would fit them either though it's probably more likely to be possible. -------------- next part -------------- An HTML attachment was scrubbed...
