to je fizicki nemoguce. da uzmes u obzir da vuces jednako dugo na vw i meh modu nemoze bit isto, otpor je taj koji tu igra ulogu, a na vw modovima jos vise trosi sam mod bateriju, i dalje upitnost baterije..... da ne duljimo, sve je relativno. recimo ona plava baterija/ neznam cija je sa ft-a,kod frenda radi super mjesec dana i onda prek noci puf, padne na pol kapaciteta. a pari na origigi skoketech modu. a nekima takve baterije traju i traju. ali se pokazalo i kod njega jer je tvrdoglav kad sam mu microcoil slozio od 1 ohm(ispod tog mu nece okinut) da mu je bat trajala krace za duplo i to na kangeru t3

Možda niste znali šta se krije iza inicijala AW i koje su to ustvari baterije.

AW is actually the initials of Andrew Wan. He owns a company based in China that has been selling batteries to hobbyists since 2005.

When a company manufactures batteries, they “bin” the batteries by quality. Andy purchases top bin batteries from premium manufacturers. He then takes those batteries and puts them through his own testing. If they pass his strict testing, he wraps them with his logo.

For instance, AW’s line of LiNiCoO2 cells use these Panasonic batteries. The protection circuit he uses in some of his batteries is his custom design and build (and many consider it the best available). He was also instrumental in bringing IMR batteries to the hobbyist market and popularizing them there.

Puno je na tržištu lažnih baterija, a AW se najčešće krivotvore, kako znati jel lažnjak, neznam, vjerojatno se to pokaže vremenom, kad crkne prije vremena, a onda je kasno za reklamacije.

Modovi, akrilni stalci i 3D printanje

da te pitam, posto si spominjao osnove elektrotehnike i te fore, jesi li skolovan u tom podrucju ili ne?
bila je ista ovakva rasprava na drugom forumu i ista frka. jedan clan je morao nacrtati da se skuzi o cemu se radi, pa evo te slike ovdje.


i ponavljam jos jednom, radi se o VW modu o kojem pricam cijelo vrijeme. Ako se na modu naredi 9W, iz baterije se izvlaci 9W, a na attiju se daje 9W. Otpor attija je totalno nebitan u toj prici, jer se radi o 2 strujna kruga: baterija-mod i mod-atty.

Ovo nije prica za mehanicki mod, jer to su 2 totalno razlicita svijeta. Kruske i jabuke.


A ta baterija, ne znam o kojoj se radi, pa necu ni komentirati.
Svakako treba koristiti High Drain baterije! A logicno je da kapacitet baterije opada s vremenom i da se ne mogu usporediti nova i stara baterija istog modela i proizvodjaca.

Da, AW koristi Panasonic celije za 18650 baterije, a EFEST isto koristi Panasonic celije za 18650. Za 18500 i 18350 i 14500 i 26500/26650 (ako ih uopce imaju) pojma nemam tko im je dobavljac

Ovaj dio nije bas tocan, iz baterije ide i vise od 9w jer dio proguta i elektronika moda..

A pošto je u 90% slučajeva u igri pulsna modulacija ova slika pada u vodu

čuo sam za modove sa DC/DC pretvaračima ali ih još uvijek nisam vidio !

istina. al bit mi je bio dokazati da se uvijek ista snaga vuce iz baterije, neovisno o attiju.

nisam ni ja vidio provaria uzivo.

btw evo fino objasnjeno o baterijama, elektronici i watima. tko hoce procitati moze, tko nece ne mora.
http://www.provape.com/v/faq.htm

"Why does the ProVari need to use high drain batteries (the full technical answer)?

The ProVari uses an internal DC/DC converter that continuously monitors the output to the atomizer load and maintains a constant voltage with an output current limit of 2.5 amps ( each unit is tested to this limit in production, most exceed this limit by .1 to .2 amps). This output voltage is usually higher than the input battery voltage, depending on what the ProVari is adjusted to.

Battery output current is NOT the same as ProVari output current.

Here is an example that shows why. When the ProVari is putting out 5.0 volts at 2.5 amps into an atomizer load, that calculates to be 12.5 watts.

That means the battery has to supply 12.5 watts to the ProVari, at a minimum. In reality it is more because nothing is 100% efficient.

If the battery voltage is 3.7 volts it will need to supply 12.5 watts / 3.7 volts or 3.378 amps minimum. Because nothing is 100% efficient, let's add that in. Most ProVari devices are 90% to 95% efficient. Picking the worst case, 90%, the battery current must now need to be 3.378 amps/ .9 = 3.75 amps. That is a more realistic current draw, but it could be even higher.

WHY?

Let's take a look at what happens when the battery voltage droops lower than 3.7 volts. At 3.5 volts the battery current goes up to 3.968 amps.

But it can be even higher still when the battery droops to near end of charge, say 3.2 volts. The battery output current now goes to 4.34 amps. And we have to keep in mind that this is ONLY the average current. Because the ProVari converter is a pulsing device, the pulsed battery current can be a factor of 2 higher than the average current.

The battery needs to supply pulsed currents of over 8 amps. These engineering calculations show why you need a high quality, Low Internal resistance battery to supply what the ProVari converter needs.

Where does the internal resistance come into play? According to ohms law, when you are drawing 1 amp out of the battery , the battery voltage will droop .1 volts for every .1 ohms of battery internal resistance.

At 4 amps this means the battery voltage is no longer 3.7 volts but 3.3 volts.

If it won't match up to the demands of the converter in the ProVari , We won't sell it. This is why we recommend using AW red high drain batteries only!.

They have passed all our tests and are rated to work with the full range of voltages that the ProVari can offer."

ovo ima smisla.
