This battery offers all the same features as the eGo C, plus one spiffy extra feature not normally found on an eGo style battery.
The eGo C-Upgrade hits all of the high points of the original eGo-C battery:
- Color notification when the battery begins to lose charge
- Improved short circuit, over discharge, and overcharge protection
And it also adds a new function mode – the voltage will change as the battery power changes when this 'upgrade' mode is selected.
This battery is available in these colors:
Differences between constant and variable voltage mode
When this battery is in a constant voltage 'original' mode, it outputs a constant 3.6V. The power button light will change colors in this mode to indicate a low battery. The battery indicator light is white at full charge, and a very pleasant turquoise color when the battery is running a low charge.
When the battery is in the 'upgrade' mode, the power button will glow orange when you press it to vape. In this mode, the light's color does not change to show a low battery indication; it's always orange. Joyetech claims that the upgrade modes gives a better and more consistent vape quality. The battery puts out 4.15V at full charge in this mode, and decreases to 3.6V as charge decreases.
To switch from one mode to the other, simply turn the battery off by pressing the power off five times quickly. Then, press and hold the power button for ten seconds. The LED underneath the power button will change colors, and the battery will switch modes. The indicator will flash blue for original mode, or orange for new mode. Click the power button five times quickly to turn back on.
