Interesting thread. Just wanted to post some info. I had been looking for some additional batteries in case the US/China Tariff dispute raises prices very high. So in another thread someone recommended Illumn as a vendor and I found these higher discharge higher capacity 16340s and 18350s. So I bought a few to test.

The Vapcell (purple wrapper) INR18350 1100 batteries except on the wrapper it says max discharge rate is 9A not 10A. I tested capacity on my Liitokala-500 at a 500Ah rate and the two tested at 1097 and 1115 respectively.

I also tested 2 Keeppower IMR18350 (black label) 1200 with a max discharge rate of 10A again at the 500Ah rate and they two tested at 1156 and 1152 respectively. I think the capacity may have been larger if I tested at the lower 300Ah rate.

I may buy a couple of the Shockli’s from AliExpress but I think they are the same cell as the Keeppower 1200’s.

On a side note I went to the Vapcell site to check the security code on the batteries I bought from Illumn (yes they passed as real) but I was surprised to see on the top of the Vapcell site the words “Approved by Mooch and HKJ”. made me laugh I guess you guys truly are Internationally famous.
