The cell used can be discharged down to 2.5 volt, in my test I only discharges to 2.8 volt, i.e. I do not measure the full capacity. But then, not all lights will be able to use the full capacity.
The two batteries does not have the same current limit, on trips at 6 ampere the other at 6.5 ampere.
The current limit is placed low enough to prevent overloading the cell, this is very good for people that want maximum battery lifetime without any risk of accidents, but not for people that want to play with high current direct drive configurations.
Conclusion
This battery uses a good cell, this secures many things:
The batteries does match in capacity, i.e. they can be used in series.
The battery is very safe.
The battery has the specified capacity (But only when tested at the specified conditions).
GoingGear.com has the EagleTac batteries and offers free shipping on orders of $50 and up. (Or $5.25 for Priority Mail on lesser orders, which is how I got the EagleTac 18650 and 14500 that I reported on in the Battery Database thread.)
Presumably the white EagleTac 3100mAh uses the same Panasonic NCR18650A, but it produces a lower voltage than SenyBor /AW /Xtar.
The pcb is more silver colour compared to Xtar and SenyBor. I wonder if can produce 5A+ current.
Why are AW so much more expensive, or am I just looking in the wrong places?
i like my eagletac. good size and great mah capacity. good quality build too. i beat up on mine and they are great so far. surprisingly smaller than xtar 2600 18700 in thickness and in length. ive found even though hkj and some other testing shows it will put down 5amps my panasonic cgr still pull higher amps in my direct drive lights.
