The 900mAh Vision Spinner Variable Voltage Battery is the newest and most advanced eGo battery. Modified the circuit to enable the adjustment of output voltage from 3.2V to 4.8V as the lithium battery power decreases. It also contains a smart Buck-Boost converter, allowing you to spin the knob at the bottom to adjust the output voltage depending on your needs.
A fully charged Spinner variable voltage battery can support you for around 6 hours and it takes about 2-3 hours to be fully charged.
**NOTE** Using the battery at a higher voltage output will drain the battery quicker than when using it at a lower voltage. Be careful not to damage atomizers/cartomizers. Driving them with too much power for too long or running them dry can burn them out. We recommend you starting with a low voltage setting and working your way up until you find the right setting for your atomizer/cartomizer.
