What's inside those Kong Power Batteries?

[Mike Fortin]

Lately a few people have made claims that inside Kong Power packs that there is some sort of "reinforcement" so as to disguise puffing in the unlikely event it were to take place.

As you will clearly see in this video, there is no hidden inner workings to the pack and they are assembled as you would expect any high quality pack should be.

All your questions are answered here, Hi-Def!

Thanks Mike for the vid, it really disspells any of the rumors about the inner workings of the pack!

After seeing the vid, will be placing my order on fri!!!

Well that confirms what I saw and agrees with my theory that you wont see a puffed cell in these unless it is really bad. The foam spacing between the cells is one reason. I will agree these features of the pack are good for sure but realize that other packs the cells are hard glued together. This means that when a cell puffs it can only "pillow" in one direction OUTSIDE. With this foam spacing they can pillow on the inside and the hard fire retardant paper helps keep the wrapping of the cell from pillowing on the outside. There is room to grow on the inside and thus that is the direction they puff. I wish I still had my dissected pack to show this.
The pack I had apart that was well worn out by the way with 100's of flights, was puffed on the inside not the outside.

Also I have had many packs apart and when a cell does puff if you separate it from the pack the cell is a bag of mush and not hard. Again the Kong cells were like this on this well worn out pack.

I am not claiming Kongs are bad folks. Just trying to understand the no puff technology! I am still testing mine and it is doing very well!

But as far as I know there is no such thing as a no puff Lipo cell. If abused they can puff like any lipo cell... Lipo technology is pretty much the same from all cell manufacturers near as I know e.g. how they are made and chemistry and as such that chemistry is the same and puffing is a breakdown of this chemistry.

So if these features inside are not what makes the pack "anti-puff" then would be good if someone could explain what makes the cell (not the pack) different from every other lipo cell out there. So if it is not how the pack is made that makes it anti-puff and is how the CELL is made, how about explaining why the cell is this way and different than other cell manufacturers?

Fire retardent paper and PC boards used to make them safer????

[fiveoboy01]

I find it un-professional for a rep to bash another company's product, regardless of whether the statements are valid.

Jason,

Whom is the actual pack manufacturer (not assembler) of the Maxamp packs?

[Jason MaxAmps]

I'm not bashing. I'm just upset that these companies keep trying to scare people into buying thier products by saying that they are puff proof and have fire proof paper and pc boards for saftey.

[robmoney]

So instead of letting everyone know WHO makes the Maxamp cells (was an honest question), you tell me to buy a pack and then cut it up to see who that would be?

Dude, I would highly recommend realigning your marketing strategy, your not winning over any customers here that's for sure with product disparagement and that attitude!

Nothing personal, I just wanted to know.

Hi Finless. First up, thanks for the vids - you rule!

I've slightly puffed a CSRC battery that has the same foam spacers as the Kongs, and it didn't prevent me noticing. I wouldn't have thought the fire retardant is rigid enough to prevent external puffing, it's no stronger than the clear heatshrink that CSRC put around their packs?

The PCB boards, is that a fuse to prevent shorts causing fires?

Jason, what was the point of your comment then? Forgive me if I'm being a retard, but fire retardant retards fire - surely that makes them safer than a pack without retardant?

enjoy guys

that's why i bought zippy-r packs yesterday. fairly inexpensive and still with a 90 day warranty. these might be the economy pack.

Shouldn't there be no spaces between the cells? Having the cells packed with no gaps allwos heat to conduct out. Foam is a great insulator, with foam in between, you're basically trapping heat for the middle cell. If there were gaps but not shrink wrapped, that would allow air to flow and reduce temp that way. Just wondering.

Here's a pic of a CSRC batt that shows what I'm on about - the strips create an air gap, and the heat-shrink doesn't cover the sides so you get air flow. Finless was saying that he noticed his thrashed Kong puffing slightly to fill the air gap. The Kongs are completely covered in shrinkwrap, so they wouldn't get the benefit of air flow, but the gap would provide some heat relief...

That's exactly what I'm talking about except one thing. In the case of Kong power, the gaps are detrimental. Air is the best insulator (foam is basically air trapped in some material). So the gaps do not provide heat relief, it provides heat retention for the middle cell and the inner side of the outer cell. You have gaps, leave the packs open.

Good point! Hmm, dare I take to 'em with an knife? On second thoughts, if it ain't broke why fix it - I don't have heat problems...:)
