I'm clueless when it comes to the subtleties of these lithium-based batteries. Until recently all I knew about lithium was that I had to take some every morning with my Wheaties or the day wouldn't go well . . . :-)
The main thing that catches my eye when it comes to batteries is "SALE!" and of course, Ah. The one down at the bottom that looks just like Jeff's battery is rated at 36 Ah. Here's the lineup: https://tinyurl.com/r9nampq They're on sale for a few more days. People are buying these things for scooters and other applications where deep-cycle performance is optimized in the battery design - or, at least that's been the case when it comes to lead-acid/flooded cell/AGM/SLA/VRLA(and subdivisions)/GEL, etc. Deep cycle batteries will quickly be ruined if used as a starter battery. However, with these lithiums, these traditional distinctions may be obsolete. Reading the text from their website, "Switch from those heavy Sealed Lead Acid (SLA) batteries to lightweight and fast charging Lithium Iron Phosphate (LiFePO4) starter batteries" These lithium batteries, despite the fact they're being used for scooters and wheelchairs, are being described as "starter" batteries. So do they serve equally well as both starter and deep-cycle? I don't know enough to say. This one at $306 with free shipping, has 36 Ah and looks very close to the dimensions Jeff specifies in his description. 36Ah is more than twice the Ah of Jeff's battery yet is virtually the same size. https://tinyurl.com/uv9rbke LiFePO4, as opposed to Lithium Ion, is less dense. So . . . two batteries of equal capacity, one of each composition, will differ slightly in size, Li-Ion being more compact and smaller (but almost insignificantly so). It is claimed that LiFePO4 can go a couple thousand start cycles. Lithium Ion (like Jeff's battery) is listed as good for 500 to 600 start cycles. There will be other relatively minor differences such as performance at very cold temperatures. One type over the other may prefer a different charging procedure . . . I've only gotten so far into this interesting subject so I hardly know anything. I'm still at the Neanderthal level of "If it doesn't throw your shoulder out of whack to pick it up, it can't possibly be a very good battery." As a very initial impression, it seems that LiFePO4 has some advantages over Li-Ion - besides being significantly less expensive.
