Just thought I'd update with the discharge test results of the Boston Power Swing 5300 batteries I bought (just 4 samples from a US supplier on eBay) since they're the leading candidate for a small range extender pack:
They fare average, keeping 90.9% of the 4.2V discharge capacity, with a discharge characteristic similar to LCO, though from what I read it's a Li-Manganese battery (NMC?). Will be interested to see the 2C charge tests once I get my 10A battery tester in a couple weeks. A 96s2p pack built with these cells should have a capacity of ~3.2kWH usable.
