    What button top battery to replace AW IMR 18650 3.7v 2200mAh ?

    Li-ion cells do “calendar” age as well as cycle age. The cycle aging, being used, can age them much faster. There is a continuous buildup of certain layers when not being used that interfere with efficient operation over time and there’s always some continuous degradation of certain compounds...

    Battery Charger-MC-3000

    There are too many undefined variables to answer those questions. It is a MUCH more complicated topic than that video makes it seem. Temperatures, charge current, charge voltage, discharge current, discharge cutoff voltages, battery chemistry, age of the battery, etc., all have an effect on...

    Battery Charger-MC-3000

    Yes, charging to a lower voltage can increase cycle life. But the number of times you need to recharge increases due to the lower capacity of the cells due to the lower charging voltage. This can counteract any gains from charging to a lower voltage. Unfortunately it takes months of testing to...

    Murata VTC6A? First I've heard

    Wait...you really meant VTC6 and not VTC6A? Those VTC6A codes I posted might not be correct then for your VTC6.

    Minding Your Mechs Ep019 - Defiant Designs TS voltage drops for different contacts, uploaded

    In this video I test the Defiant Designs TS triple 18650 mech squonker, including the gold-plated and silver-plated contacts and also contacts I sanded. I test whether a smoother contact surface helps to improve (decrease) the voltage drop of this device. Thank you Defiant Designs for donating...

    Murata VTC6A? First I've heard

    The Murata VTC6A 21700 has been around for a couple of years but it takes time for excess inventory to appear on the gray market and become available to the distributors. There is no true continuous current rating in the datasheet but there is a temperature-limited 40A rating (keep under 80C)...

    Have you ever had an inexpensive (less than $5 each) USB “charger” burn out or fail?

    Agreed. But many people call them chargers and would have no idea what I was referring to if I asked about power supplies. It’s one of the big reasons why I am asking what everyone calls these things.

    Minding Your Mechs Ep018 - Defiant Designs DS Testing Part 2 - Does contact smoothness matter?

    In this follow-up video to the voltage drop testing of the Defiant Designs DS mech I test whether a smoother contact surface helps to improve (decrease) the voltage drop of this device. Can the performance of the gold-plated contact used in Part 1 of the DS testing (Ep017) be improved?

    Minding Your Mechs Ep017 - Defiant Designs DS Voltage Drop Testing - Part 1 has been uploaded

    In this video I test the voltage drop of the Defiant Designs DS dual 18650 squonking mech. I also compare the voltage drops of the gold-plated and silver-plated copper contacts. Mech Mod Voltage Drop Table, results of all my testing: Mechanical Mod Voltage Drop Table | E-Cigarette Forum

    Bench Test Results: Xtar ST2 dual-4.1A charger

    The test results have been made public: Xtar ST2 4.1A Charger Test Results | Battery Mooch on Patreon It did pretty well in testing and could be a good choice for those looking for a moderate to high-current charger for 1-2 cell charging. I don’t have any other charger recommendations yet...

    Will a 40T last a day ?

    Using the actual amount of energy (Wh) the 40T delivers at about 60W, which is 10Wh, we get about 10.8 minutes of vaping time. That’s 216 three-second draws at 60W. At 55W you will get a few more, very close to the number @greek mule calculated. Whether that’s enough to get you through a day...

    Have you ever had an inexpensive (less than $5 each) USB “charger” burn out or fail?

    That’s the link I’ll be posting after popping open a few of these cheap units to show their crappy construction. No need for me to duplicate his amazing work. :-)

    Have you ever had an inexpensive (less than $5 each) USB “charger” burn out or fail?

    It burned out though? Do you know it’s model number?

    Have you ever had an inexpensive (less than $5 each) USB “charger” burn out or fail?

    If yes, I would like to hear about it! If you know the manufacturer and model number please let me know so I can order a couple. I have a few different ones now, costing around $3 each, that I will be testing but I want to test more of them. After that I hope to test some of the high...

    The Efest LUC V8’s display (batch 1) and iMate R4’s LEDs are too dim!

    I was really looking forward to testing these two new chargers because they looked different and the LUC V8’s display was gorgeous in the promotional images for it. They’re both unusably dim in my opinion though. Compare their promotional images to the photos I took. The differences are huge...

    Xtar’s E-cigarette Safety Shield (ESS) technology tested

    Yup. A common circuit but the concept is not used nearly widely enough IMO. I’m just glad to see a China company promoting it as a separate feature worthy of its own discussion.

    Xtar’s E-cigarette Safety Shield (ESS) technology tested

    Also called E-cigarette Security Shield. This is the tech Xtar is putting in their newer chargers and, if I understand correctly, they are offering it (via licensing) to mod and charger companies. They have a short promo video, linked at the bottom of this post. The ESS module is basically just...
