Contents of this video:
00:05 Bat-safe overview
Small overview of the Bat-safe box to show the measurements and accessories included .
01:45 Bat-safe test #1
Testing the Bat-safe with one 4S 5000 mAh battery. This battery is about the same as a common Phantom battery and this test should address most of the UAV users that use batteries this size.
03:10 Bat-safe test #2
Testing the Bat-safe with one 6S 16 000 mAh battery. This is one evil battery. The battery is most commonly used in big drones like DJI S1000, FreeFly Alta and custom built ones. NOTE: This battery is 60% over the Bat-safe limit!
Conclusion - out of all test I have done so far, the Bat-safe box is best solution for storing small and medium sized batteries. There was absolutely no signs of a fire on it after the first test, which it contained very well. Also both the walls and floor were unharmed. However, I would not suggest using Bat-safe box for batteries bigger than the allowed rating.
In both of the tests the battery fire was triggered by overcharge.

That second one is friggin' HUGE! LOL!! @ 5:00 looks like a brisket! LOL

[@RonnyKing]

I love how it says in the description "this is one evil battery". Hell yea! That thing was not messing around! Then again: I can only imagine what this would have done if that box hadn't been around...

[@Xbot4Life]

It helps you appreciate how much energy is stored in these batteries.

[@frankposterello1628]

True, I wouldn't re-use the box after a fire, and as stated, that second battery is way over the limit. But it's still a useful data point to see - I probably wouldn't even push the limit they claim (6S-10Ah). That 6S-16Ah looked like a Saturn V taking off. I'll probably limit myself to 3, 3S-5000mAh.

Sir. I'm curious as to how you can confidently say your second experiment was conclusive after re using a box that has already been compromised by a previous outing...

[@ZEN43D]

Apparently Bat-Safe say you can reuse the safe

[@chosenone1004]

Joe Buske Excellent point . That’s the same exact thing I was thinking . That box is 100% compromised after the first battery . So I believe the second test isn’t accurate . Even if The manufacturer says it can be used again I wouldn’t . That 6s lipo going off was in fucking sane ! I watched a 6s go off in another video and I swear it’s the equivalent of a jet engine ! I think I’ll just stick to my lipo bag inside a ammo box and continue keeping it in my shed . I’d rather lose my shed then my house

[@BigJimMartinGuy]

At 3:05 it states the seals are undamaged after the first attempt. I guess you either gotta take the word of the person who was there, or listen to the armchair experts.

[@magnusjohansson295]

With a 3S this should be quite adequate protection then it seems.

[@ELValenin]

So as long as the batteries aren't over 222wh combined it's safe?

[@ubreakitirepairit3569]

Lets just take a moment to appreciate how that elastic strap out lasted the box at 4:26

[@Jexzi]

How long did it take for you to receive the package? Did it come through DHL? I just ordered the XXL for my e-bike batteries and it's been a week since I've last heard from them (via email) I spammed them concerning my order cause I felt like It was possible that I was being scammed. We'll see I guess…👀

[@kevinf.9561]

Thomas, Is the max capacity of Batsafe theoretical or based on real world testing? If based on testing are there any videos at max capacity? Thanks.

[@trystanmarshall1867]

The box failed to contain the fire because it was compromised from the last battery that caught fire you can only use the same box once after a fire happens

[@Sugalime3D_FPV]

That is heavy 16000 is like 20 small 800 mAh 6S batteries. Such a big fire. Wow.

[@eugene188]

But testing a larger capacity battery on the already damaged bat-safe doesn't really work right? Once its been burned, I would expect someone to get another instead of using the same one again, even if it survived.

[@michaelwilkes0]

do they make any larger bat safes that i can keep the small bat safe in ?

[@ValFPV]

Lmao

[@daquino0021]

Great video! I may have to pick up several of these. I have 14 sets of batteries, 4 per set and need to figure out a safe way to store them. Can you tell me what the rating is for these Bat Safes?

[@RajuCam]

This one is rated for 6S 5000mAh if I remember correctly. They also have a new XL one, that supports more batteries. You can charge and store up to a 4pc 6S 5000mAh equivalent (500Wh) safely inside the BAT-SAFE X large.

[@daquino0021]

Thank you for the info! I just took a tally of how many sets of Lipos I have... 15 sets of 4 lipos a piece (all mainly 4-cell and below).. thats a lot of lipos! I'm planning to relocate all of my Lipos to my detached garage. My only concern is that it does get fairly warm in there during the summer months. I just plan to keep them there, away from my condo, as I have pets and wouldn't want any harm to come to them. I do keep them in storage charge when not in use and only charge the ones that I know will be used in the next day or so.

[@swashbucklingadventures9929]

@ 3:03 mmmm.....bacon! LOL!

[@michaelwilkes0]

was the big battery at storage charge, full charge, or overcharge? I think it was overcharged, which of course is the best test of the box and easiest way to make a lipo fire on demand. A storage charge fire of that size battery would be a lot less of course. Do you think the flame would have burst out the seam if the battery were at storage charge?

[@brianwest2775]

They definitely purposefully apply current that will force it to catch fire. There wouldn't be much point doing the test if you didn't start with a fully charged battery, although people often do these tests with batteries that are at end of life because, well, money.

[@hubsan1489]

that screem in the black gorund 0:30¨LUL

[@karrotop]

faaaaaark! I guess there's a reason they set the max mah at the level they did!

[@gerki_fpv]

Great Video. Its possible to store 4 x 6S 1300 mah inside or is that to much?

[@alcurtis93]

130wh at full charge. See if that fits with the batsafe spec

[@RobertNES816]

You're not supposed to use this container again after the first lipo goes up. It was basically useless for the second test.

[@newyorkcity76]

What about ebike battery 48 v let me know please ?

[@chrisspaulding7589]

thats crazy, my lipo bag went up in flames also

[@figit090]

Not terribly impressed by your test using an already "spent" bat safe. I consider these and their construction to be a one-time-use disposable wear item. Once it's saved you, get a new one. I'm curious if your first test compromised the top vents, causing a more explosive result. The first test shows good venting out of most of the holes, while your second video looks choked a bit. This could cause excess pressure in addition to the battery puffing. Without a new box you introduce variables... you could have tested the same pack twice, but moving to a bigger pack with a used box isn't very conclusive.

[@RajuCam]

On Bat-safe webpage under FAQ there is a question about re-use and the producer has stated that it is OK to re-use the same box multiple times. The failure with the bigger battery has most likely two simple reasons - the battery pack expanded and pushed the lid a bit open and the box is not rated for this kind of battery.

[@danizweifler6061]

@@RajuCam hey..... !!......perfect answer.... I F THAT IS THE CASE.......... = but you should come up with such K E Y I N F O S right away in the video !!

[@phase0100]

When I use two or three battery with 5000 maH, one is on fire and the other infected with fire and explode. Also, one Bat-safe for each lipo? Expensive hobby.

[@derfacecrafter1869]

but less expensive as one house for each lipo

[@alcurtis93]

One batsafe for the rate wh capacity. Doesn't matter the number of batteries at long as way under threshold

[@athefpv4670]

I always suspected lipos were made in hell

[@kb25j]

What about using a fireproof safe for home (documents, jewelry, etc...), like a Sentry? Would those be a good alternative? If they're rated to withstand a home fire, they might be a good option, no? They have pretty thick walls

[@spartancaptain5691]

No, it isn't vented and would likely explode.

[@cicciottobiscotto5070]

I have a question: since you state the capacity of the battery, I assume that: 1) You set the batteries off when they are fully-charged 2) A battery going off at storage charge (ca. 30% capacity) would be less destructive than a fully-charged one. Are the above assumptions correct? Thanks for the videos! :)

[@RajuCam]

Cicciotto Biscotto, both correct. A battery in storage capacity is a lot less likely to go off and when it does, it is less agressive.

[@Xbot4Life]

This is why i only charge on the day, i wont charge and leave over night. And i aint touching 6s

[@williamhoodtn]

I don't think it is a fair test given you had already damaged the Bat-Safe seals with the first test.

[@vincentmounsey]

would the box had done a better job with the 6s if the box didn't have the 1st test done?

[@RajuCam]

Most likely. Be aware, that the box was not rated for the 6S, so there is no surprise that it went in flames.

[@Sugalime3D_FPV]

[@alcurtis93]

You can go above 2s. Thank of the all the e-bikes in the world with huge wh batteries in them at 10/12/13/14s

[@derfacecrafter1869]

ok, thats a big battery

[@kekoaandthecrawler4580]

Well the second test was pointless because even though the battery was bigger than the box is rated, the insulation already was compromised so the second test would have had to be done with a new box to have any point.

[@danizweifler6061]

Hi Kekoa // I did watch the vid 2 min ago (Fr, 05.08.2020)..... // it is great, that "RAS" had chosen exactly the kind of lipo safer box, I do intend to buy.... :-) // I don't think, the 2nd test was pointless; although the box had been "pre-damaged" // however: for an absolut realistic result, it would have been mandatory that "RAS" uses an brand new box..... = you are absolutely right !

[@DavidKenneson77]

The box was already comprimised for the second test.

[@cesco_rc]

That was what I was thinking too. So second test should have been done in a new Bat-Safe.

[@user-qw2tt6su7p]

probulary would have ended the same tbh, if the metrics are true, 60% extra of overhead for tolerances seems too much to ask for

[@abzyberdy]

OOOHH. I hope you was not testing that at home

[@rcrockracer8985]

What if one lives in an apartment? Fire may be contained but what about the smoke? No one ever talks about the smoke. I'm going to have to give it all up. Can't take the risk & Nimh sucks. I'm sad.

[@70MikeMike]

Rc RockRacer it’s funny you mention this. 2 weeks ago I was using an imax b6 Charger and charging my MJX Bugs 3 lipo and my apartment caught on fire. We have been stuck in hotels since then waiting for the repairs to be completed. I wish I would have known the dangers of these batteries and chargers. I guess you live and you learn.
