Protection Circuit on 18650 batteries

[paulishuku]

Hey Everyone,

I have a provari, and just got a rebuildable atomizer. I have a couple of 18650 batteries, but on 2 of them i cant go over 3.8 volts without tripping the protection circuit on the battery. Can i safely remove the circuit without the battery blowing up in my face? The battery is around 6 months old, and its just not tripping while getting above 3.8 volts.

Is it safe to do until i get some new batteries?

your pushing too many volts for what ever ohms your coil has your batteries are fine and no you cannot remove the protection

"I have a protection circuit doing something it is designed to do. I don't like it. Is it ok to remove it?"

In a word: No!

The reason I ask is because ProVari has built in protection for over amp and will usually throw E1 or E2 error codes when this happens.. I have exact same battery when pushed to 4.3 volts with exact same atomizer, it does fine.

Your trying to use more amperage than they will allow. What it will do is just not fire. Crank down the voltage and use it in the 8 watt range. Next time get batteries w/o the PCB protection if you want to use higher wattage/amperage. Keep in mind also that the provari had built in protection. You want to go low ohms and High wattage you need a Mechanical Mod anyway. Mech's dont' have as much trouble with batteries of any kind as long as you don't exceed the amperage rating of the battery. FYI voltage is pressure, Amperage is flow and ohms resistance. Watts =V*I. No battery will let you go ape on current. I have heard of some 30amp batteries but I don't need them. Have not found it necessary to exceed 4 on my mech. Here is a chart you may find useful.View attachment wattscalcdhartv1.pdf and an exel sheet. View attachment wattscalcdhartv1A.xlsx

Kind of reminds me of the old Doctor joke. "Doctor it hurts when I do this". Doctor says' Well don't do that'. FYI if you try to remove the PCB you will ruin the battery and probably draw a nice arc when you try to cut or chisel it out.

No, it is not safe. The issue is that batteries that have a protection circuit built in are generally ICR chemistry. Batteries that do not have protection circuits built in are generally IMR chemistry, also known as high drain batteries.

If you draw too many amps from a ICR battery it will go into thermal run-away, vent and likely burn. If it burns quickly enough (and they can do that pretty quick) the resulting event might be called by some an explosion. IMR batteries do not do this.

ICR batteries can produce much less power (amps) than IMR batteries.

The Provari is designed for IMR batteries and will protect the battery to the extent needed by them. It will significantly over-draw a ICR battery with no built in protection.

Don't do it.

Yes you can...it is INCREDIBLY inadvisable...but there is a reason they sell batteries without the protection circuit on them...if the device it's powering itself has overcurrent protection

Just got a VAMO V3 had the same problem...couldn't turn up the wattage without the battery protection circuit kicking in and turning off my PV

I followed this and it worked...I also ordered 2 18650's without the protection circuit

Good luck...as long as you DO NOT short out the terminals and cause a high current/high heat situation (or low ohm coils)..you should be good to go
