Hi, I'm trying to decide which of these batteries to get to use as my stay-at-home device. I currently have a micro ego that I take w/ me, it's 350mah and hits like a beast when fully charged and then slowly gets weaker as it depletes. Some say it's 3.7 volts, others say it's unregulated and over 4 volts when fully charged. What I want is a battery that's twice the size/capacity and produces the same amount of vapor (or more) as the micro does when it's fully charged.

I'm looking at the Riva SE here - Electronic Cigarette - Batteries - Riva 510 and the joyetech eGo here - eGo 650 mAh Joyetech Battery - vapeBIG - which is better for what I'm looking for? I've read the Riva has a better button but the eGo has the full voltage feature which I kinda like the idea of so I'm leaning more towards that one at the moment. If someone could tell me what the voltage of the SE Riva is that would help but I really wanna know which one is considered the better battery. Thanks in advance.

Hi darkhood
Dont know much about Riva. Some say Riva is like Kgo.
But to compare Ego vs Kgo:
Kgo usually starts out at 4.2. Stays at about 3.7. Said to be an unregulated battery.
Ego battery is regulated at 3.3-3.4 volts.
I like Kgo better. Mine is a 1100 mAh & lasts all day. Same physical size as Ego.

I have the riva 650 mah...I really like it and recommend it. I just ordered the Riva 900 mah, just because but I would love the mini too. The 650 lasts all day for me. It is a bit stronger at first, then stays the same all day and then right at the end of the batt life it goes pretty fast. I have not used the ego so I can't compare but I like the Riva enough that I just got another one. Vaping it right now!
