    Sony VCT5A Batteries

    If I analyze it in my bare eyes :) down to 3.2V (most of the mods that are not Mech-Mods) the VTC5A and the VTC6 will give similar Wh for the vapers under 20A CDR. However...sind we don´t vape with continously discharge current, finally the VTC6 can deliver more Wh...

    Minding Your mAhs – Ep19 – Is pulse battery testing more “real world”?

    From my experience with eBike batteries I know, that the internal resistance (impedance) is an impotant indication to the performance of the battery at its life time. So if the 21700 from Molicel has at the same specification like the 40T a higher internal resistance it means, that the battery...

    Molicell P26a 18650’s

    Most probably the deviation is caused by the Charger and does not mean difference in your 2 batteries. Those Chargers are not really accurate. They are however doing a good job on Charging

    Source for AW IMR 18650 Button Top or similar?

    The NCR18650A has (had?) 3100 mAh and the NCR18650B 3350 mAh. There was also an NCR18650G, that been told to have 3600 mAh...never had it between my fingers. The good thing about those Panasonic cells was their integrated PTC, that kept them very safe for various of applications. For vaping...

    Panasonic NCR2070C Vs. Molicel INR20700A

    Mooch - do you know, if in the size of 20700 the NCR2070C would currently have the highest performace? I havn´t seen any battery in this size at this point, that has such a high capacity with 30A CDR....

    Panasonic NCR2070C Vs. Molicel INR20700A

    I meant of course NCR2070C and they are sold by IMRbatteries for example. I wanted to order some for my own experiments...asked my own source and they will get them in few weeks as well :D

    Panasonic NCR2070C Vs. Molicel INR20700A

    I see, that the new Panasonic NCR2070C is already available at some retailers shops. I was wondering, if there are already comparisons between this battery and the Molicel INR20700A? From the technical specifications I found, it seems like this new panasonic battery has higher capacity and lower...

    All known manufacturer of Li-Ion cells like Samsung SDI, LG Chem, Murata (Sony), LG Chem, Panasonic etc. manufacture their batteries with flat-Top. The "convertion" into a button-Top is done by battery assembler so-called down the line. It is easier to weld the button-Top via a wire, rather...

    Well...I don´t know LIION, I just know, that I once bought from Amazon in Germany those types of batteries (mainly assembled that way in China) without protection circuit for an halogen lamp. Those lamps draw lots of current while turning on and my battery got really hot. But if the provari...

    Usually on a button-Top, that is welded directly on the cell, you would see the welding points. This is what I mean by saying, that the button-Top is welded via a wire. It does not mean bad quality of battery and has nothing to do with reputation of one reatiler, or another...just that the...

    Looks like a Button-Top, that is wired and not welded to the battery. In most of the cases the wire that is used is not good for more than 5A

    Best battery for long vape time? Provari 2.5

    Very important is to be sure the Button-Top is directly welded on the battery. If it is a kind of button-Top, that is welded on a nickel wire, you will have performance problem most probably...

    Question directed to @Mooch

    I think that finally people who vape must deal with the matters of batteries exactly like they do with other matters of hardware, or liquids. To the re-Wrap-Companies I wrote it once and I write it again - every one cooks with the same water. There are no special batteries for vaping and...

    Question directed to @Mooch

    You have those batteries made in Germany with a protection circuit at 15A: ENERpower VC+ Battery 3.6V 3000mAh Button-Top 18650 (protected with 15A PCB) – ENERprof Those batteries are of course more expensive, but this batteries can hold double as much current

    VBatty/VariCore 32700 7000/6500mAh 35A LiFePO₄ review

    With its 141 Gramms you can carry almost 3 x 18650 batteries and 2 x 21700. Maybe can be used in a mech mod a special design for Body Builders :D

    VBatty/VariCore 32700 7000/6500mAh 35A LiFePO₄ review

    Thanks for the link, but frankly speaking...why should any one use such a big cylindrical cell in LiFePo4. Many of the manufacturer of LiFePo4 are offering Moduls of LiFePo4 in a so-called Pouch. If I need lots of capacity with LiFePo4, I would always prefer such sulotions

    Bench Test Results: Vapcell Blue 30A 3750mAh 21700...accurately rated, great performer

    I think, that in regulated Mods actually the Wh as a total sum of Energy is more important than capacity. Especially if we consider the constant step-up in the mods, the performance of the Voltage is a major indicator, of how warm the mod would be. We are talking here according to my...

    Bench Test Results: Vapcell Blue 30A 3750mAh 21700...accurately rated, great performer

    Thank you very mooch :D again and again and again for the great job you do. I was wondering, if it is possible after so many batteries you had seen to predict the chemistry of the battery according to the structure of the discharging curve? We see differences between LCO, Mixed chemistry, Li-Mn...
