Good morning Ecig Forums... I hope I find you all well?? Greetings... Peter from Oxford in the UK.
I joined as I am having problems which I attempt to explain below... I wondered if any of the technically adept members could help me find a solution as I have reached a dead end....
I bought an Itaste 134 Mini a couple of months ago and I am very pleased with the unit overall, however, when trying to purchase some 18500 batteries I have come up against a problem which is confusing me I wonder if you can help me solve it?
I bought 2No Efest 1100mAh IMR18500 3.7V Li-Mn batteries. V1. (Red).High drain rechargeable battery. (Photo 1 attached).
Unfortunately I cant seem to get them to work. This is where the confusion begins.
If I install the longer tube and insert the battery with the same polarity as the smaller Trustfire 18350 batteries that came with it, (with + on the top), I get nothing no lights.. no sign of life at all. However, if I insert the battery upside down, (with the up) the lights go through the red/yellow/green start up cycle, but when I press the button to vape I get the flashing red fault light, as if the voltage wheel is not in place . This is confusing me
So I took the batteries to my fathers house and put them on a battery tester and the tester shows them as outputting at 3.7V with the correct polarity .. Why would it work upside down but test correct polarity on a tester??
Ive purchased another set of batteries now, (Photo 2 attached) And I seem to have the same problem with these, except when I turn them upside down I still get nothing... I have just fully charged these so know that is not the problem.. . This shouldnt be this difficult surely!!
Have I bought the wrong batteries?? If yes, can you let me know which ones I need please?? Is this a problem with the longer extension tube??
I should point out that the small Trustfire batteries I got with it are 1200mAh and the new ones are only 1100mAh . Is this the problem??
Any help/information you can offer would be appreciated?!


Yours expectantly.... Peter.
