Battery Voltages -- Surprise!

[Scottbee]

Please re-read my post.

I believe the poster made an error.. assuming that standard 510 chargers are like the ones that come with the disposables.

No sir, I did not make an error.

Hook one of your KR batteries up to a 5V power supply, go to bed, then see if your neighbors are kind enough to call the fire department when your house catches on fire.

The KR batteries REQUIRE an external SMART charger, not just a 5V supply. The disposable 510 batteries have a crude internal charge circuit that only requires an external 5V power supply.

The only mistake I made was assuming regular 510 batteries were like this as well. Now I know they are similar to KR batteries.

So what exactly qualifies at a "smart" charger?

I'm really hoping we don't turn this into a charger thread......

A circuit designed to properly charge li-ion batteries.

Scott, I don't care to turn this into a charging thread, but I need to get my point across as it seems to be flying over some peoples head.

There are two different type of batteries out there......

Some batteries like the KR808-Dx/501/M40x do not have circuitry built into the batteries to monitor/regulate the charging process. These batteries require an external circuit to properly charge the battery.

Now, there is another type of battery out there. Batteries such as the 510 disposable and a variety of other generic super mini's do not require an external circuit for charging. They can be charged by connecting any 5V power source.

These batteries have some sort of charging circuit internal to the battery. This might be as simple as an over-voltage cutoff, monitored by the same uController that does the cut-off, under-voltage, LED control, etc.

The last thing you want to do is connect a battery in the first group mentioned above to a "charger" designed for the second group.

Here is a picture of a 510 disposable "charger"......



Do you see any electronics in there? Would you even know what to look for if there was?

There isn't any electronics in there because it's not a charger, it just a USB to female 510 connector.

So what does the charging then? Oh that's right, you believe in magic.

The way I read it, Scottbee never said what you apparently think he said. In fact, from what I understood, he's in agreement with everything you said except this:

"KR808-Dx batteries do not have any internal charge circuitry, so hooking them up to a 5V supply (510 charger) will destroy the battery."

Which *is* wrong, since a 510 charger isn't just a 5v supply (The first part about the Kr8 is right) - and you acknowledged this in an edit, which he probably didn't see because he responded to another poster's quote which didn't include your edit. So from my view, the whole thing is just a misunderstanding.

P.S. (Edit) Wishing to prevent any further misunderstanding, if you remove "(510 charger)" from the quote above, the statement is correct and I *think* everyone is in agreement with that. Note: 510 charger != disposable 510 charger - and I'm sure everyone agrees with that.

[Wall]

Where is the picture of a STANDARD 510 charger, disassembled to show us no circuitry to make it safe for charging batteries that dont have the electronics built in?

No one is arguing that the cheap-disposable-chargers that come with disposable 510 batteries are SAFE to charge other batteries without built in protection.

The point being made is, that the standard chargers that come with non-knockoff 510's, are smart, ie have the protection built into them. So in that case it is double redundancy, since the 510 batteries also have the protection built in. They can be used to charge batteries without the protection built in.

Summary: Don't charge other batteries on knock-off chargers that aren't built for that purpose.



Re-rail: Great test Scottbee, makes me more eager to build a solid 3.7 mod for my 510s

[tribalmasters]

Very nice test! I'm a bit disappointed that my new Tornado(ego) isn't giving me the best performance

I wouldn't be.

The "cone" on the eGo/Tornado is more than just an aesthetic device. It changes the "draw" on the unit, preheats the incoming air, and bumps up the overall atty temperature a bit. All of those contribute to the "vaping experience".

Don't get me wrong though.. I will certainly be trying an eGo/Tornado at a true 3.7V just to see what it is like.

I didn't even consider that, since the enclosed air around the cone is being heated by what would normally be warming our finger as the atty gets hotter?
