riva 510 battery voltage & smart chargers

[ProNoob]

I just made my first major ecig purchase and am waiting for the order to arrive.

this is my first post here so im limited to posting in this forum even though my questions are technical.

Ive read that a full charge on a riva 510 battery is suppose to be 3.7v, but Ive also read that this isnt true that it is really 3v. Can someone clear this up for me?

Is the charger that comes with starter kits a dumb charger? If yes, is there anywhere to buy a smart charger? If not is there anywhere I can buy a generic smart charger where I can set the full charge voltage to cut off charging, so I can mod it to work with my batteries?

I have also drawn up, mostly completed (just waiting on the 510 fitting to arrive) and tested a homemade true usb 5v pass threw, made out of things I had lying around, if anyone is interested in a write up.

I have heard that the Riva is a true 3.7v whereas it's sister, the eGo, is actually more like 3.2v.

Sorry I don't know what a smart charger is, but I can tell you that it's the sort of charger that stops charging once the battery is fully charged (if that's what you're talking about, I don't know).

YES! that is what im talking about. I was really worried about the shelf life of these batteries with a dumb charger, can anyone else confirm that these kits come with a smart charger? before I leave my batteries on the charger overnight.

A smart charger stops and cuts off at the prescribed charging level. When you see the green light blink briefly while it is charging, it's checking the voltage. Then it switches back to charge mode again until the voltages match when it checks again.

Can't say for sure on the Riva, but it's more than likely the same as the Ego in vape voltage. 3.2vdc is about what you get with the atomizer screwed on and drawing current. This is because the voltage is maintained at the same level throughout the vaping cycle to give you the same vaping experience from first to last puff, then it cuts off and flashes the led to indicate charging is needed.

The Riva 510 charger is a smart charger. Li-ion batteries were initally rated to charge to 3.92vdc. The military discovered that life is greatly extended if the charging level was reduced to 3.7vdc, thus the cutoff on the smart charger. The voltage drops quickly to 3.7v if you charge it to 3.92v anyway, so the stress of charging to 3.92v doesn't give you much charge life and it greatly shortens the number of times the battery will accept a charge.

thanks davep thats the exact information I was looking for.

I did think it was really weird that the retailer i ordered from told me they dont make smart chargers for ecig batteries that they have ever seen.

Why do so many post in this forum say not to leave your batteries charging overnight?

There is alot of bad information circulating the internet and even retailers, its very confusing for a new vapor.
