GrimmGreen Battery Safety

[sonicbomb]

During the following review of the Ruby he demonstrates his use of a Brillipower 18650 in a mechanical mod with a 0.19 ohm build. That's +22 amps from a 15amp CDR cell, which is obviously not safe.

He talks about Battery safety at the two minute mark, then at 03:21 he says -
"I don't think they are the best batteries on earth, but for this application it's working just fine."

It's perhaps easy to point the finger as we here on ECF are in the privileged position of having access to the true values of a large number of cells thanks to @Mooch s testing.
I know anyone can make mistakes or be misinformed, but I refuse to believe someone this experienced and involved in the vaping scene doesn't know that re-wraps with inflated specs are not to be trusted. His statement about them not being 'the best' proves that he at least suspected that they were inappropriate.

(At the danger of sounding ....-hurt) In my opinion a respected reviewer (who regularly mentions battery safety in his videos) with a quarter of million subscribers cannot afford to be this ignorant, or display such a lackadaisical attitude towards battery safety. If he was unsure, he shouldn't be using them, let alone mentioning them during the review.

I tried contacting him to point this info out, but as yet I have not received any response. I'm willing to put this down to him being a busy guy and not the alternative.

He melted down the sled of a two cell mech box by putting one in backwards.
He managed to grab it in something and get it outside to finish venting.
Minor floor damage and he kept his hands. Lucky boy.

If it was me, I'd say "Jim... that was truly boneheaded, let's make sure we never have that happen again."

He appears to have gone the opposite route and said "That wasn't so bad."

Do you think he has dry knuckles too then?

 

[Annie56]

40amps, eh? So who's telling lies? The maker of the battery, or the vendor who rewrapped the battery?? Either way, lying makes me sour. Shame on Green for using a crap battery. He has access to the best batteries and the best knowledge base.

*Thank Heavens for ECF and its knowledgeable folks!!*

Don't want to Freak any Vapers out, but the Data is available on most batteries on CandlePower also.
Also lots of data available searching Google, including scientific testing and comparison of 18650 format batteries.

All ECF Data is searchable also - R.I.F.

I quit following him since he called me name after I pointed out that Wismec Reuleaux DNA200 and RX200 are not the same in the episode where he used skin wrap (stickers) for one on the other and it didn't fit perfectly.

Don't know why more data would freak people out, but... who knows.

A Google search got me some 2013 charts from the Candlepower forum (not the bulb MFG ) but it's a massive flashlight oriented board and I didn't find updated results.

Could you be more specific?

GrimmGreen Not! the sharpest knife in the drawer He makes a lot of Stupid! mistakes, I'm not surprised he dropped the ball on battery safety as well How ever what is surprising to me is how he can have all these subscribers watching his Dumb Videos!

Well, individual searches have worked for my particular battery needs.
Samsung published an excellent data sheet on the 25R

Here is an 18650 Abstract:
A Comparative Testing Study of Commercial 18650-Format Lithium-Ion Battery Cells

Most Commercial Cell(Authentic) Data will be a few years old as very little has changed with exception of release of the LH HG

* Only Special interest will provide Data on Re-wraps. Why? Secondary(Generic) suppliers are concerned with Sales, not statistical data. The less we know the more they can sell. Avoidance is the best policy.

That appears to be a fine general report on the 18650 format, but even though it's barely a year old, it's of limited use otherwise, for us.

These were the cells they tested...
"Tested cells, from left to right, UltraFire TR18650 4200 mAh, UltraFire TR18650 4900 mAh, Sanyo UR18650FM, Panasonic NCR18650A and Panasonic NCR18650B."

Yes, "special interest".
I enjoy seeing others' test results as well as Mooch's.
And comparative charts have their place vs. the few MFG's data sheets.
As you note... the rewrappers aren't exactly forthcoming with data of their own.

And there's always some new rewrap that he hasn't tested yet, while others may have.

Thanks anyway.

Not saying @Mooch doesn't do a Great job. In fact the work is invaluable to the community.
Am saying the data is out there, or will be shortly after new product hits the market and the GrimmGreen's of the world need only put forth a little effort.

@Mooch Data and test information is easily found in the mix when searching Google.
ECF links show quite often.

If anyone knows mooch's works - Search < Mooch battery > produces:

I'm going to tack this on the end of this thread because this guys credibility is in shreds anyway.

Riptrippers abuses an Imren 26650. He may not have had the true specs, but he knew damn well something was wrong, but used them anyway and 620,000 people potentially get the idea that battery safety is for fools. What a git.

Mooch just tested this cell and it has a 10 amp CDR, and a poor performer at that.
Imren Purple 22A 5500mAh 26650 Bench Test Results...only a 10A/5200mAh battery!

23 amps from a 10 amp battery, sick as tats. Skip to 02:25

 

[Jim_ MDP]

Can't believe I made it to four minutes.
Speaking of tats (the non-tattoo kind)... he gets on mine.

I want to like Grimm, I really do. He seems an otherwise decent guy.
I have absolutely no such feelings towards Rip. A total caricature.

I'd rather sit through a Bogan vid.

GrimmGreen Not! the sharpest knife in the drawer

Indeed. Nice tats though...

I have seen more than couple respected reviewers drop really crappy batteries into mods during a review. Hopefully no one buys their batteries based on what they see some of those guys use.
To me if you really need to use batteries with inflated ratings even though you should know better, I can't help you much other than to say, please stop doing that. At the very least, load the battery in the mod before you start so people don't see it or use an actual good battery maybe? They are not that expensive and maybe will help avoid some newer folks buying them. These companies will keep pumping out new batteries with exaggerated ratings as long as people keep buying them.

40amps, eh? So who's telling lies? The maker of the battery, or the vendor who rewrapped the battery??

There are only a few battery manufacturers in the world who make their own "cells", including LG, Samsung, Sony, Panasonic & Sanyo.

All the other brands on the market buy the second and third tier cells from those manufacturers and re-wrap them under their own brand. These are "second and/or third tier cells" which did not meet the higher standards of the original manufacturer. In order to compete with the original manufacturers' batteries (first tier), these other companies feel obligated to publish specifications which are inflated to make them appear superior to those of the original manufacturer.

* (AW is Andrew Wan, a former Panasonic employee who branched out to create his own "brand" of batteries. He allegedly has agreements with the major cell manufacturers to purchase first tier batteries from them. Not all batteries are created equal, so AW tests these batteries for quality. The best get chosen to be AW brand, and are re-wrapped as AW.)

Do your research before you buy. Decide what battery to buy depending upon the application that you will use them.

I know Grimm Green and Mooch have had a few conversations together, and Grimm has actually spoken of Mooch's battery tests in a couple of his videos. It's a shame that he decides to publicly show his use of batteries of questionable quality on camera.

I think it was the review team House of Hybrids who actually showcased Mooch with a videoconference on batteries.

<--- reallife Mooch

(Mooch's segment starts at 41:00)

I like to watch/listen his vlogs from time to time, tho.

All the big reviewers are not really trustworthy anymore as they are too invested in reviewing which requires a constant stream of freebies to continue and a couple are damn right fraudulent in their reviews calling everything great when sometimes it's very clear things are not good. Rewrap company's have been throwing freebies around lately trying to get higher exposure and at a time when they have started showing up on certain reviewer's channels. These days the only thing YouTube is good for is to actually see the product as for the review part it's worth less then the breath they use to give them and anyone who makes vaping purchases based on YouTube reviewers probably deserves what they will get.

Forums are the place to be if you need help or advice and whilst forums have their share of shills the number of responses from known members usually means your getting genuine information not paid for promotional hype.
