i know that all 18650 cells are supposed to be 18mm wide and 65mm long but i also heard that the higher mAh cells such as these

are a bit thicker and may be too tight to fit comfortably in a vamo ..any feedback appreciated guys and gals

They fit, as I had them in my V2. Thats the 3400mAh ones

Just make sure you are getting the ones you think you are getting.
For the record my greeen NCR18650B are the same size as the CGR18650CH (grey) & I would guess they are the same size as the NCR18650A which you posted, but also CGR18650CG & NCR18650PD also come in the same green colour & appear to be exactly the same size.
The bigger ones would be the repackaged ones, eg Efest3400mAh protected which is slightly wider & longer, but inside it is an NCR18650B

thanks guys ..question for AndyC1971 what voltage should they read fully charged .my charger turned green so i tried them and only read 3.9 volts in the vamo ..is that right ?coz my cheapo 18350`s hold 4.2 volts fully charged

 

[AndyC1971]

Have you got a multimeter fella??

Which ones did you go for in the end??

I have just checked a fully charged NCR18650B 3400mAh battery: -

Tesla shows 4.1v

Multi meter shows 4.2v

got the 3400 mAh ncr 18650b ....maybe cheapo charger turned green too early then .i only got 2 cheapo chargers ,the one i used for the 18650 i never used b4 as i`ve only had 18350 `s till now .

EDIT : i have now put the ncr 18650 b in the other cheapo ."multi size springy type charger" to see if it will get them up to 4.1/4.2 .as that seems to work fine with my 18350`s

I am using an nitecore i4, but if they are charging the 18350s to 4.2v, I would expect them to charge these.

I have received my 3100 mAh protected 18650s from Fasttech (Didnt order the 3400mAh) So I am charging those up as we speak, and I will post my findings.

Pop them back on charge for 30 mins, and see what reading you get then.

i have now put them in the other charger that i use for the 18350 now and see what happens .

AndyC1971 no improvment on 3.9 volts sadly ..and it gonna cut off at 3.2 volts .so thats gonna be no better than sticking with my shitty 18350`s fook my luck huh
