the O-Phos & the v1 are simply 2 rebranded chinese batteries. (or probably untested Joyetech clones? ... ) And in my opinion they also could be considered variable voltage batteries because they are unregulated!
I personally dont use my omicron v1 anymore..., the voltage is not stable enough to be able to make a proper use of my 1.5 carts... where the go twist does its job very well.
Now with stable 3.2v I'm able to use my 1.5 carts properly without any risk of overheat. And my battery lasts longer... because of the low voltage.
And I also feel safer because I know this ego battery has been sold ten thousend of times , what means they are tested a way better omicron batteries ever will be, if they are tested at all.
Interesting observations, I don't have an O-Phos, but believe it's a V1 with a built in charger? Yes, they are Chinese made, but I don't think you can call them 'rebranded' unless you can show me the same exact thing with another name on it? Since all similar batteries I can find have a different connector, and the only ones with the same connector are different models I think THC's claim that he orders his parts made in China is honest and accurate. Who's design is he 'knocking off'? Where can I buy the
same thing cheaper with another name on it?
I bet he would say he's 'getting them custom made for him'? Same as say a GM wiper motor?
You're welcome to your opinion of what variable voltage is, but that term has been already defined for public use long before you were born. It means one you can
vary at will. I'd advise using a more technically correct term. Maybe 'unstable'? Or 'not controlled' or 'not regulated' (only I'm pretty sure V1 is in fact regulated ....), but "variable voltage" is already defined as something else. As to 'proper use' you are again welcome to a personal opinion, but the
maker I think gets to tell us how his device is intended to be used and he seems to feel the cart was developed to run on V1s? I bet he considers the V1 proper, and it is his call?
And I wouldn't be too quick to slam the V1 with 1.5s over overheat. Specifically maximum output (fresh charge) is 3.18 Volts in my tests, which I think you agree is less than 3.2 so it should actually be a bit cooler on the V1 at the most? And since 'buck/boost' circuits are typically in the 'low eighties' efficiency wise, 20% of the energy is lost in the regulator, the batteries therefore last a considerably shorter time delivering the same energy to the load. Same as you car MPG goes down pulling a trailer. You might go just as fast, but the tank of gas won't carry you as many miles.
I'm glad you're happy, that is after all the goal. Your logic is, I think, flawed, your 'facts' wrong. I'd hate for some innocent take them otherwise......
Limited bravery, but I have a coffee break tomorrow (not now- it's 4am) and I recently purchased a meter. I also happened to watch a youtube instructional on how to use said meter, so I might be able to deliver some results.... is there something I could test here? (well there's lot's I could test- anything on this ego c twist that I should test, or that you'd like me to test?)
Cool, hard to get really useful numbers without a load on it, but it'd be nice to know what the "open circuit voltage" is on the various settings. You can probe right at the connector on the center pin with one probe while holding the other on the outside. Watch out for shorts to the wall, it's supposed to be protected from such abuse (shorted carts), but no sense testing that part out if it fails.....
Thanks.
