I purchased one of these LiitoKala 26650 cells a month ago during the AliExpress Anniversary Sale. See this post for my initial capacity test. Many buyers are measuring capacities around 5400mAh, which is substantially higher than HKJ’s tests of both Cyan and Black LiitoKala 26650’s. Unfortunately, I have no way to test high-current performance, but my cell appears identical to HJK’s and arrived in the same packaging. I paid US$4.02 for a cell with free shipping, which is likely an unbeatable value for an FT03 power source.
They are sold by the liitokala Official Store, though no one can understand the array of LiitoKala store fronts on AliExpress. I also purchased an Lii-500 charger from the same store and the battery and charger arrived together in the Eastern US in just over two weeks; the fastest AliExpress delivery I’ve ever received.
The store I purchased from does appear to sell fake 18650’s, however, as do all LiitoKala stores that I’ve found. I cannot tell which, if any, LiitoKala AliExpress store is the real one, but the store I purchased from has been around longer than the others I’ve seen.
When it comes to LiitoKala, nothing seems guaranteed, but I can report an excellent buying experience with the store linked above. JasonWW’s cells are certainly interesting as owners are measuring capacities closer to 5000mAh, which may imply better high-drain performance, but I’ve seen no testing.
