Nice one mate! Currently on a week long research binge for the NOCO batteries as a replacement for my 2010 RT battery. Unfortunately it looks like no matter where I search, the size 20 (NLP20) and above can't be shipped to Australia or internationally. Even though they're the safest of lithium batteries. So it looks like I'm stuck with getting the size 14, the NLP14. It's a bugger, because the 20 has 7Ah output, but the 14 has just shy of 4Ah output I believe. But it DOES have 500A cold cranking amps, which is plenty to get her started. Going to have to just try it. Thanks for posting this - definitely needs to be more examples of people switching to LiFePO4 batteries for the Spyders.
