26650s beat 18650s in holding voltage, that’s what they are really good for…I learned that with the BLF A8 which has really nice runtime
The Efest 26650s are really nice if you don’t consider the miserable capacity.
What about paralleling some 18650s?
I tried once to order efest batteries but never got an invoice, I am really confused about their shop.
With these currents the protection circuits are suboptimal as they steal voltage, I have seen some nice tests here from night crawl or so which compares the Panasonic PD with the Samsung20r and the conclusion was that the Panasonic are better(almost same voltage but more capacity) below 7A and from that the samsung is better. So HKJ graph from the enerdan PD is different…
Here it is
But if you can use 26650s than this doesn’t matter anyway…until you go in the 15A field
