So if i want to make changes or upgrade from the cheap 650mah Ego, Is there any suggestions?
If your eGo-style
batteries are not variable voltage, you could get some like that. They're often named "spinner" or "twist" because of the variable voltage dial at the bottom. If you want longer battery life, you could get higher mAh.
You could, however, upgrade to a "mod." These are larger and often more versatile. They generally come in two types:
The most popular mods are variable voltage and/or variable wattage devices with protective circuitry and, often, other features as well. Structurally complex, some of them are nevertheless quite easy to own and operate. The iTaste MVP v2 (comes with an internal battery and charger) and Sigelei Zmax v3 (
batteries and charger would be extra) are two examples of relatively inexpensive but good quality mods of this kind (both are about $40-45 each). ProVape's ProVari is an example of an expensive but extremely high quality mod of this kind ($150+).
Mechanical mods are structurally simple devices, just a battery compartment with some vent holes and a simple button, but more work to use safely. These are not usually recommended to beginners but, if you become interested, people will be willing to help you. Some really good ones are available in a range of prices somewhat similar to the previously mentioned variable voltage mods.
