Αν κάποιος ξέρει αυτό το αφρώδες υλικό σαν κόλλα τι μπορεί να είναι ? μήπως έσκασε το PCB ?
Τι μπαταρίες χρησιμοποιούσες ? μήπως έβαλες flat μπαταρίες όχι imr
Βρήκα ένα ενημερωτικό από την Provape για θέματα μπαταριών, μήπως είσαι σε αυτή τη περίπτωση
For those who own a ProVari we want to remind everyone that using the proper batteries is VERY important. While you might be able to save $5 by using generic batteries, its just not save and not worth the $5 savings if you damage your ProVari and have to send it in for repair. Not only does this cost time and shipping expenses but if we determine that the cause of failure is using improper batteries or using magnets, replacing the circuit board will end up costing you more than just getting the proper batteries up front. Never use magnets or flat top batteries!!
We suggest you only use the AW red high drain batteries. These are the batteries that we trust and know to work and be safe. Any other kind of battery is not save and there are lots of cheaply made batteries on the market that are not safe to use.

Are Li-ion Batteries Safe and which ones should I use?
The amount of power required to run an eCig requires a battery that can store a large amount of energy and deliver that energy on demand rapidly. Because of this requirement lithium ion batteries are the best choice. We all need to respect the amount of energy in these batteries.
But are they safe?
We all hear about the occasional incident where a battery fails in a violent way. This is caused by a short circuit within the cell or if stacked cells are used, one cell can discharge into the other with high discharge rates when one cell depletes its energy before the other.
A mild short will only cause an elevated self-discharge. Little heat is generated because the discharging energy is very low.
If, however, for whatever reason any of the following conditions happens;
1. Internal short circuit
2. Excess external charge current
3. Excess external discharge current
4. Environment conditions
The temperature can rise to the point where thermal runaway can happen that results in 'venting with flame.'
There are two basic types of lithium-ion chemistries: cobalt and manganese (spinel). Typical battery chemistry mixes are cobalt, nickel, manganese and iron phosphate.
Lithium-ion cells with cobalt cathodes should never rise above 130°C (265°F). At 150°C (302°F) the cell becomes thermally unstable, a condition that can lead to a thermal runaway in which flaming gases are vented. To achieve maximum runtime, cell phones, digital cameras and laptops use cobalt-based lithium-ion. Because of the lower temperature whereby the cell becomes thermally unstable, electronic protection circuits are added.
Manganese is the newer of the two chemistries and offers superior thermal stability. It can sustain temperatures of up to 250°C (482°F) before becoming unstable. In addition, manganese has a very low internal resistance and can deliver high current on demand. It is these two features that make this battery the best choice for use in the ProVari. The drawback of spinel is lower energy density. Typically, a cell made of a pure manganese cathode provides only about half the capacity of cobalt. The higher inherent safety of the spinel system permits the exclusion of the electric circuit in the battery. In the ProVape eCigs we incorporate the protection circuit into the eCig thus providing an added layer of safety. We know of NO safer combination then to use the manganese lithium ion battery with the ProVape eCig.
The AW IMR type cells that we carry use the manganese chemistry and are the safest of the lithium chemistry types.
The higher capacity cells use the cobalt chemistry with the electronic protection circuit.
The ultimate in safety is to have multiple redundant safety layers whereby if one layer of safety fails the other layer prevents an unsafe condition. This is what we strive for at ProVape, even if it means more internal components with its associated higher cost.
Asia produces many non-brand replacement batteries that are popular with users because of low price. Many of these batteries don't provide the same high safety standard as the main brand equivalent. A wise shopper spends a little more and buys a higher quality battery with its higher level of safety.
It is NOT recommended you use an unidentified lithium-ion battery from an Asian source.
As a consumer, you are in a position to select the highest quality and safest equipment. With each purchase, ask yourself,” Are a few pennies or dollars saved worth the safety risk?” Ultimately, your personal safety is in your hands with the equipment you buy.
Today, lithium-ion is one of the most successful and safe battery chemistries available. Two billion cells are produced every year. But be aware that there are several lithium ion battery chemistries being sold in the market. Some are safer than others.
