Hi guys. I want to buy batteries in advance.
What do you advise?

I bought some Sanyo NCR21700A 5000mah Tesla batteries. They perform better than the 50E and 48G. You can read about it here.

Tesla 21700

[image] [image] 1) Charged starting from 3.4V, so not fully discharged, the image above does not show the full capacity. 2) Charging capacity is always different from discharge capacity. 3) My discharging function on my charger doesn’t work, waiting for a (better) replacement charger which is currently backordered, so can’t do a proper capacity test atm. 4) Just ordered a controlled load to have another device to test with, this one here reviewed by HKJ: Test/Review of Electronic load 60W, …

Look at these comparison graphs, it can maintain voltage better than the other cells for the entire duration of the battery capacity.

I bought the Sanyo NCR21700A from “Vapcell Dennis”. The price is so low I will not post it here. Give him a PM on BLF. Also, you might want to order the button top version because the standard version is recessed and will not work with most chargers. The button top version adds some resistance so you don’t get the full 15A continuous rating.

If you want max turbo output, then get the 4000mah VTC6A or 40T. From my testing on the C8F 21700 and TK01 (both not as powerful as this light), I see literally no difference in measured peak turbo output between the VTC6A, 40T, and the 3000mah 30T and even if there is on a light like the E07, it will be hardly noticeable base on my experience testing numerous 18650 high output lights with different cells.
