Have you tried the Ultrafire XSL 2600mah? I see that it's protected, and I've read too many stories from people saying the Vamo doesn't work with protected batteries
So there is no confusion - I use the RED Ultrafire XSL 18650's in the Vamo - These work flawlessly and have never misfired.
There are, for some unknown reason, several versions of the xsl 18650 in RED/BLUE/GREEN. Blue is low discharge and a general application battery. Green, I have no clue.
RED is high drain and handles 3+ amp loads.
If you think you have to worry about what battery to run in a $35-$400 Mod, Consider having to choose what battery to power the High torque Servos in an $8000.00 1/3 Scale r/c Air Craft.
Also be aware any battery that ends in FIRE probably comes out of the same factory. You could almost consider these as model grades rather than different companies. Some are bottom of the line and others get progressively better depending on Spec requirements.
AW is just that - A SPECIFIC Spec requirement to present for sale as an AW battery - AW is a reseller not a manufacturer(from my research)
