Among the stuff I ordered lately, here's this eGo VV battery ordered directly from China. (In case you're new to this, VV stands for variable voltage.)
Length: 108mm/ diameter 14mm (ilonger than standard eGo battery)
Voltage: 3.2V-3.7V -4.2V
Best match: ECHO cartomizer; eGo-T Atomizers
Charging time: 2.5 hours (Charged it a dozen times already and this is correct)
It has manual voltage regulation. Voltage settings are 3.2V-3.7V-4.2V, suitable for most 510 atomizers/ cartomizers.
I tried it with my CE4, clear clearomizer 510 and ViviNova mini and it works fine with any of them.
The eGo VV battery comes in default
mode of 3.2V
To change the voltage you need to press the button 5 times quickly and the LED ring below the button will change colors (i.e. voltage settings) from red to purple. Pressing the button quickly 5 times will change the voltage in the following sequence: 3.2V (red) - 3.7V (purple) – 4.2 (blue) – and then back to 3.2V (red)
This battery has overcharge protection. Once the charging is done, no more current is supplied to the battery. LCD power indicator bar in the bottom shows the remaining power.
Well, it certainly looks interesting with all the lights. There is an observable difference in vaping at 3.2V vs 4.2V and it certainly is a change in comparison with my old standard eGo-T battery.
As far as I'm concerned, this feature is not so special to make me permanently switch from my old battery to this one. However, some readers might find this battery much better than the regular (standard) eGo.
Update after more than a year (it's April 2014 now and this review was written somewhere in December 2012). All in all, this battery lasted for quite a few months and considering its low price we can say it was well worth the money.
