Battery Venting and Exploding

[Sweets]

Good day.

I would like to put my 2c in as well.
Firstly i use a mech everyday ( VGOD pro mech 2) with a vtc5a with a 0.14 build on it.

I know that is exceeding the CDR. But i have come to learn my cells, what they can and can't handle. I always check the wraps and the positive side of my cells if the 510 didn't dent it in.

The heat of the cells is the other thing i check when exceeding the CDR. Just adding that i don't chain vape my mechs. I also understand that i will probably have to replace them each year rather then every 2 + years because of the way i use them..

I have a general rule of thumb to replace cells after a year... Even if they are still fine...

i do NOT encourage this by me posting this...even if i use a mech within the cells CDR i still check the heat though... But i have found that my sweet spot is 0.12.

Above is one post made by Mooch.

Thank you.

While you may be able to pulse your batteries above their CDR rating for a short while, a potential problem is if your mod gets stuck in an auto firing position in your pocket and you dont know about it. Or it could be in your car etc.

Then it could overheat and vent

Thats one of the reasons why its not recommended to build a coil that results in an amp draw above the CDR (continuous discharge rating)

So what happen if you run a battery to flat? Will it explode?
Reason why I ask. I have this headlamp that I use for fishing. Now this is a meneer se headlamp. I can see if the guy fishing on the other side of the dam, brushed his teeth. It takes two 18650 batteries and is led.
It came with two chinatown 18650 batteries, but they last like 15min on full bright. So I want to put some authentic vape batteries is.
The problem is that with these led lights they normally go off only when battery is really drained.
The bigger problem is the two batteries sit on the strap at the back of me head.

Never had a problem with the chinatown batts, run them till light goes dead and then in charger they say 0% when put in.

JCV buy 2 pairs normal 18650 install in fish finder on garden chair[DAYLIGHT] Test your casting in the pool , if they fad [bats] , charge and put new set in , I Think youll be red but unexploded [and the chair]

That is true @Silver

Taking extreme precautions are vital. When im done with my mech and im out and about.. I remove the battery. If i want to take some hits i just insert it again.

I had two new almost battery vents this week. One with a VTC6 and one with a Basen 26650. I was looking at some of my older mods I never use and they don't have battery orientation on them and I put them in wrong... the smell of burning and the heat build-up tipped me off and managed to get both out of the mods in time... the batteries were pretty hot but the mods seemed to be OK.

Wow! Glad you're okay! You see even veterans can make little forgettable mistakes! This is just a good reminder to keep cautious with batteries and mods!

A month before lockdown, I wasn't paying attention, and my wrap had warped a bit, I thought "meh whatever, re-wrap later", the insulator ring had come out without me realising. The resulting short produced enough heat to melt the plastic behind the contact on the mod.

Don't be lazy like me even with regulated mods.

Thought I'd ask a question here instead of a new thread.
I once had 6 x Samsung 30Q 3000mah batteries (2 sets of 3 married batteries, always charged in unison).
I sold 4 of them.
The remaining 2 batteries aren't married (1 from first set, 1 from second set).
Can I still use them in a VV regulated dual-battery mod? Considering they were both used at the same in the same way but in different sets, but unmarried, is there still a risk? Sorry for stupid question, not clued up on this.

Yeah you can use them brother.
Just take note after you use them and you stick them back in the charger that they both draining equally within +/- 0.1v .
If they are not equal you will be straining one battery more then the other.

Depending on what charger you have, you could measure the internal resistance of each cell and if they were almost identical it would be safe.
So say 20mOHMS and 19mOHMS.

If your regulated device is say a DNA device, it does have some balancing features that would protect you in case the batteries were unmatched.

I don’t recommenced the methods above without taking into consideration that it is far easier to just purchase two new cells for added peace of mind if you don’t want to become a battery enthusiast overnight.

Another issue is that a lot of the well known and readily available batteries punch higher in their label amp ratings than they actually do in real world tests. Interestingly the molicels push out almost what they are actually rated for on paper which is why there is such interest in a battery that performs almost identically to what is stated.

Sorry, how do I see that they draining equally? I have a Nitecore i4 charger. I've noticed with my current set of dodgy old batteries when I charge them, the one sometimes has a 1/4 or 1/3 of a charge left and the other is flat, but can only see this with the light indicators, no display or anything.
