VTR very fussy over batteries

I am assuming that they will actually stop working at 3V, or is that what they are recommending?

I think its the same as all these type of batteries robby the safe discharge is 3v below that damage start to occur

Well I finally cracked open this and got 8 18650's good for mech mods as there protected:

one of the batts: 18650 icr

I have ordered one I am sure I can strip it no problems but do you have any tips for anyone else on how to open the case I have my dremel at the ready waiting patiently for mine

not bad for £13 for 8 of em lol @ £1.62 each

all I can say is when there low the atty gurgles lol and always shows 1 led a light when I put em back to recharge on the i4

Good plan, before I got a battery checker I just judged when the vape was a bit cool and weak and changed it. It always seemed to be about 3.2 ish volts

So it`s not protected in that way ronaldo , just need to be careful, a battery checker is a good investment

Good idea but I don't fancy hitting that with a hammer LOL andy01424

lol prise open case with flat screw driver,your a Mod Destroyer or wanna rename to BatDestroyer

I can see it now (just like when I tried to fix my roller switch)....paper cuts on fingers and busted finger nails

No!!!! My hands are way too precious

yes a battery checker would be a very good idea that's another thing I should get thanks robby for emptying me pockets again I will buy you a pint if I ever have anything in my pocket and we meet

A possible negative is that they are 18.4mm wide, may be tight in some mods and mechs.

good point that but there is plenty of room in a vamo so if people want them for there focal vamo they should be fine

Please don't tell fiddles and teethcv but ronaldo and robby have hijacked this thread LOL

and not one word of smut

andy01424 ronaldo I would assume that they have no protection circuit in the battery themselves and are designed to be used in a cellpack that has the protection circuitry built into the cellpack.

I would at least cut the top off one to see if there is a protection circuit on the battery before using it.

when I cut the battery pack open to get the batteries out I will test the circuitry it the pack to see what protection there was but computer battery packs normally self regulate they normally switch of laptop when each battery still has 3.2 volts left in them

That's what I was saying. The pack itself has the protection to regulate the batteries inside it. Taking the batteries out will remove any protection, leaving you with ICR uprotected batteries.
Not good if you suffer a mechanical short as they tend to explode.

From looking at the Smok 18650's there the same design ,also same as ones torchy boy sells[have 2 blues] as for the circuitry i believe in the battery packs is the charging board for the lap batteries for recharging the lithium battery,as a motherboard does not contain one

"The cells in notebook batteries need to stay connected in order to maintain the flow of electricity. This requires the terminals on a notebook battery be soldered together. Many notebook battery manufacturers insert the connected cells into a plastic sleeve, which they then seal at the seams with a special ultrasound machine. Their goal is to keep the cells tightly and densely connected, since the notebook battery pack has to meet precise tolerances to fit inside your laptop.

At one end of the notebook battery pack is a small circuit board that electronically senses the charge and discharge levels, as well as the overall state of the notebook battery, i.e. how much charge is left. This component is absolutely critical to the notebook battery pack; without it the lithium ion cells would overcharge and overheat."
