The majority of my 18650's are Eagletac protected's. Mainly for the base cells they employ. 2500's would be in the majority, with 3100's next. I even have a few of the old original black and red 2400's that are still going strong. 99% of my charging is done with a 4 bay SoshineV3 and I also use a 2 bay Pila on the oddest of occasion's.
Orbtronics 3100s, great customer service from them and very high quality so I'm sure I will stick with them. Last order I placed was on a Saturday right after lunch and the package was delivered Monday afternoon. How many companies receive an order on a Saturday and get the damn thing out the same day. :thumbsup:
Good question. I've been trying different brands to get a feel for what works,what doesn't.
i have some Panasonic NCR18650B, some Eagletac 3100 protected, some Olight 3400, and sone Nitecore 2600.
if I could find a reliable, cheap USA based source for the NCR18650B, I would probably standardize on thrm.
Various from Samsung and LG 3.8v(4.35) and do notice a longer run time between charges. The KeepPower 18650 from 3100mah to IMR 30A 2100mah
Lots of sanyo 2800 and pany 3100/3400 protected and unprotected.Sony vtc5,efest 3400mah
All my lights are fed,usually down to the output to mah,example my tk61vn uses sanyo 2800,my tk75vn uses pany 3400,sr52vn uses KPs 3100 and miniVN 3400 efest.
No fav cells,just what is best food for a specific light for value/runtime/performance
I guess thess pany cells are one of my used be it protected or not
These efest 3400 are good value cells
Single cell i tend to go with unprotected,mutli protected cells,high A like vinh lights then IMR
A123 3.2 Volts 18650 Lithium : Iron Phosphate cells (I have bought two, and they last surprisingly long in my handheld 520nm green direct diode laser, and might be used for SST-50 white LED flashlight or a 5 - 10 Watts 365nm blacklight flashlight eventually).
