Removing protection from battery - NOT ADVISABLE !!

[kasad]

Hello everyone!

tldr: skip to the end, there's question there

I was getting tired of EGO and since I'm low on cash I bought imotion 2v+ (chinese provari ripoff)

It served me well, only (unprotected) battery that I got with it was 1500 mAh and VERY bad.
Ie I would get 3 hours of vaping then have to charge it for like 7 hours.

So finally yesterday I get some 18650 (They are not available nowhere nearby)
They are Trustfire 18650 2500 mAh 3.7V.
But my pv won't work with them.
I figure that pv's pcb kicks in together with battery's protection and it fires for a split second and turns off
displays random error (all leds lit on display so 88 which isn't an error code at all, there are only 2, f1 for faulty atty and f2 for short)

So, finally I get mad because I already gave away ego's and passthrough
And I remove protection, similar to this guide: How to remove protection circuit from 18650 batteries. - Laser Pointer Forums - Laser Pointers and Laser Pointer info

Now everything works fine, I can vape like a champ. And I noticed that battery is now same lenght as my original battery. (tho this one has button top)

Question:
Is this safe? Is removing protection from this battery potentially dangerous? My pv acts the way it's supposed to. Everything is fine.
I just wan't to ask to be safe.

Thanks in advance.

Regards
K

There are good explanations as to why.

NO!!!!!!!!!!!!!!
The protection circuit is there for a lot of reasons! It stops over charging, over discharging and maintains the battery at a safe level! Why does your PV not work with this, because the battery isn't designed to provide the load your PV needs to function properly! You are risking the battery venting, at the least, and have the chance to become a statistic, missing part of your face and tongue at worst!
Subtlety isn't my strong suit, so here it is, this is STUPID and DANGEROUS!
You need to get IMR batteries, a safe chemistry that will supply the load needed, and not blow up! I'm sorry, but you really are playing with a dangerous force you don't understand at all! Read up, and educate yourself before you are injured, PLEASE! Basic to Advanced Battery Information from Battery University
Really, this isn't something be taken lightly, I've seen what can happen when batteries go wrong, there is a LOT more energy than you think, and I wont own an unprotected battery!

I have read the entire thread you posted, this was done for use in a laser pointer or flashlight.
My concerns are they have not continued to post updates or findings in that specific thread, they have not said it is safe.
They have advised the OP to buy the correct batteries. Perhaps this maybe a quick temporary fix but not a solution and with very Catastrophic Results. DO NOT DO THIS.

I would not advise anyone to take the Protection chips off their batteries if they do not know what they are doing, and what the consequences are. Completely Irresponsible.

The Trustfire 18650 is a Li-ion battery and has a protection circuit for a reason. I'm not a battery snob but there's no way I would use that battery without the protection circuit. Get some AW or Efest (IMR type) batteries.

Buy an ego twist/vision spinner.
Do not take them apart.
Throw the rest in the bin before you hurt yourself.

(edit) okay, sell Imotion.

Honestly, you really don't need to throw your Imotion(pic) away!

Buy the correct batteries.

Try not to buy any batteries the word *fire* on the end.

Never modify batteries. NEVER EVER!!!

No. It is not safe to use an unprotected Li-ion battery in an APV. Use one protected ICR or better yet: one IMR battery.

Heck, I posted at Laser Pointer Forums a while ago when I built a unique 660nm handheld.

First 660nm in progress - Laser Pointer Forums - Laser Pointers and Laser Pointer info

NOT SAFE. DON'T DO IT!
As for the device, I had an IMotion V2 a while back. The batteries that I got with it were terrible. The performance was anemic, at best. I was about ready to give up on the IMotion, and chalk it up to just being a crappy device. But, as a last resort, I put one of my AW IMR 18650s in it, that I use in my Provaris, and the IMotion worked perfectly. My gf still uses it daily.

Like everyone else has said, not safe - don't do it. You risk fire and explosion which is not good when you have it in your mouth! That PV comes with an IMR lithium ion battery because of the high power it can draw.

Unfortunately, IMR's don't have the high mAh capacity of the regular lion batteries. For the best of both worlds you can buy a hybrid like this one. It is IMR and has 2250 mAh capacity.

It is interesting that your original battery gets used so quick and takes so long to charge. Both are not normal. If your modified battery charges much faster in that charger then the original battery is likely bad. Good luck and be safe

Sounds like it needs an IMR battery...like others have said above. High drain (Higher amp limit) and safe chemistry.

IMR won't explode (well, not as easily/quickly). Make sure the device is vented while you are at it.

The protection is there to stop battery overheating. The battery will work for a while before it gets too hot. But it degrades over time. Once it starts a runaway reaction, it's a bomb if enclosed. Get the proper battery.

ETA. Bigsmke beat me by 30 seconds. lol.

Its called PROTECTION for a reason!! While you may get away with it for a while, one day what it was there to protect you from will happen. And you won't be protected, then you will wish you had protection......

I just got the imotion2 V+. I am using efest imr 2000mah batteries. I get the 88 error code when I use cartos below 2ohms. the lowest i got it to work is with an atomizer (joye type) at 2.2ohms. thet being said, maybe it's not a battery problem you are having when you said you get an 88 error code.
and oh, it's bad to remove the protection on the batts.

 

[waygookin]

follow up question. is it normal for the imotion2 V+ to not work with low resistance attys/cartos? i have 2 batts, both efest 2000mah imr. both of them will not work when i use attys/cartos below 2ohms. even 1.9ohm does not work even at 3V setting. i am not having any problems with 2.8 and 3.0 ohm clearomizers though. even at 6v.

right now i am thinking of buying 2.5ohm cartos. any ideas if this will work? just need someone to confirm before i order.

Also entered into first post.

First of all. Thank you and everyone else for warning.

I just have few questions. Battery that I got with device is unprotected. Joytech mod uses unprotected battery, all because both charger and pcb in the pv protect the battery.

Does this TrustFire 18650 li-ion have different chemical composition then AW IMR or no name unprotected battery that I got with my pv.

What are the differences?

Thank you everyone!

NO!!!!!!!!!!!!!!

The supplied battery is an IMR, again, the safer chemistry that doesn't need a protection circuit. If you would please read the link I provided you would understand this better as they word it better than I can.
The charger and device do help, but the chemistry of the battery makes the battery itself safe so it doesn't need the protection circuit. The Li-Ion battery needs the protection circuit to prevent over discharge, over heating and over charging etc. The Li-Ion batteries are not capable of delivering the constant amperage that the IMR batteries can deliver. The Trustfire is Li-Ion, NOT IMR like the supplied battery, this is what we've been trying to say, you NEED IMR batteries to make this work safely!
