      Do you have a review for the Nitcore UMS4 charger ?
      I can't figure out how they claim 2A per slot, with 2 batteries, when the input is 3A max.
      Would love to read your thoughts on that. Got a link for a UMS4 review ?
      Thanks for all that you do !

        I believe it's 5V, because the USB QC charger I'm using lists 3A/5Vb, 2A/9V, 1.5A/12V as its output options.
        Which is the main reason I doubt it's putting 4A into the batteries. I will try to find out its wattage.
        One note, whether its because of how the brain functions on the UMS4 or what, but,it took twice as long to charge 2 of the same batteries at same starting voltage as my UM4 @ 1.5A/slot.

        Check the Nitecore web page for the specs for your charger. It shows that you are limited to 2A total charging unless you have a QC charging adapter. Then you can go up to 4A total charging current.

        Hmm...you’re using a QC charger though. It might not be communicating properly with the charger and it’s staying at 5V. Do you have a USB tester?

      Will all mod Built-in 3000mAh li-ion batteries have about the same lifetime span given near identical usage?
      Regardless of manufacture and size/shape, and all other things being equal.
      1. Mooch
        Mooch
        No. The batteries in different mods have different construction, chemistry blends, and operate at different temperatures in different even if they are the same capacity. This can lead to different overall life spans for those batteries.

      Hi Mooch. I have very specific questions re: batteries for ProVari 2.5 classic and ProVari 2.5 mini. Clearly you are the expert advice I need. Would be more than happy to contribute to your ongoing research costs. Please reply

      Hi Mooch. Like everyone else, I want to thank you for all the testing you do for everyone, both (and especially) for batteries, but your recent voltage drop tests as well (would love to see some tests on the Kennedy 21700 Vindicators if you ever get the time and opportunity). Just saw GrimGreen's latest 510 Report to find out about your update to your battery charts, and I have a question.

        Availability.
        It’s just a table of the more available cells worldwide and not a table of just the best performers. As mentioned in my posts there are many, many other great performing cells not in the table. But they are hard to find. It’s a table for new vapers, or those confused by all the choices, to help narrow down the choices to consider.

        For those who are aware of other choices they are completely free to buy and use them. If I put all the great performers in the table it would be much more confusing than it already is for new vapers. I would also get a huge number of questions asking which was “the best”.

      First, thanks for all your hard work. I don’t know who else to ask so I’ll ask you. Do you think shockli black 26650 w/button top will fit into the Geekvape Aegis. I heard they Have a larger diameter. Also, the only ones I can find in the U.S.A have a button top.
      I really want the performance as I usually don’t vape high watts. Thanks

        The button top is a lot longer than the flat top. It might not fit. Best to go with a flat top.

        Try the Golisi, iJoy, or Aspire 26650. They fit and you won't be losing much at all in terms of vaping time.

      Mooch, first off let me say thank you from the bottom of my heart for the work you do for the community, it means the world to me. When talking about Lipo packs we use watt hours, is that just because it is easier for people to understand than saying 3s 950mah? Basically isnt a 3s 950mah Lipo pack the same as 3 950mah 18650s in series?
      1. Mooch
        Mooch
        Yes, barring normal differences between different batteries and chemistries, it's the same thing.

        Different communities just seem to have different ways of rating. Some useful and some useless.

      Hey Mooch, have you ever come across Golisi batteries? They apparently have panasonic cells inside, made in Japan, then shipped off to China for the rest of assembly. They have a 40A rating on the side, though obviously this wont be close to the CDR. Just wondering if you have any experience with them. Thanks - Slack

        Shame. So far they seem pretty decent, well made and performance seems good, but without any true battery guru like you putting them through their paces it is hard to tell what is going on with them. I would imagine they are about 10A CDR given other pansonic cells on the market.

      Hey Mooch, hope all is well. Wanted to see if you have ratings for the nitecore 18650s? I saw a 30a, 35a, 38a, and 40a which i figure are some overrated 20a-25a but wanted to get your take on them. Didn't see them on your list.

        I switch constantly between setups, regulated and unregulated, 25W-120W.

        I don't pay to much attention to the coils I use as they just don't make much of a difference IMHO. It all depends on the heat flux, juice, power setting and/or battery and preheat. For a single battery mech I often use fused claptons at about 0.12 (dual).

        Sleep? :)

      Hi,
      I've read your blog and still confused to pick the safetiest battery for my mecha
      I use Broadside mod (0.1-0.15 ohm dual coil) and I use XXX battery (www.xxxbatteries.com) ,I feels like it will get warm quickly.
      Only VTC5/6, HB6, HG2, HE4 that avail in my country (some have diff spec :HG2 have 3000mAH 35A,HE4 2500mAH 35A)
      Could you help me suggest the battery that I have to buy?
      Thanks
      1. Mooch
        Mooch
        The HB6 will run the coolest and be the safest.
        The HG2 and HE4 are rated at 20A by LG and me.

      hello mr. mooch, something wrong with one of my LG brown
      when i put it in my xtar vc4 charger, it read Ni-mr not Li-ion,
      my other LG brown are okay, just this one got me curious -_-a

      this one LG brown did depleted until it unable to start up in a mod,
      when i put in my xtar charger it shows 1.55v but as Ni-mr

      am i should just throw it away or is there some solution?
      thanks :
      1. Mooch

        That battery is probably ruined, damaged at least. Discharging down to below 2.5V starts to damage it. Under 2.0V is bad. I highly recommend not using that battery anymore.

      Hey there Señor Mooch :) I have been going over your tests over the past few months and already found out that 8 of my 10 LG HG2 are fake.. I was wondering though if somehow I can measure the amps of the batteries with the equipment I have at home? All I have is an Opus BT-C3100, IMAX B6, a battery capacity discharge tester from ebay ($4) and a multimeter that only measures up to 10A.
      Thanks :)
      1. Mooch
        Mooch
        You need a way to discharge at 10A or more and to measure the temperature of the battery too.

      Hi Mooch, I know I'm going to feel like an idiot but I was reviewing your charger test results here and I only see results listed for the LUC4. Am I insane or is there only this one charger tested? I'm curious about results for the various NiteCore and other EFEST chargers.

      Thanks so much for your fantastic contributions to the community. You're my hero.

      One question, on FB you posted that you were going to test what the benefits are for marrying battery's. Did you finish that research & if so what are your findings.

        I am about 300 cycles in on the preliminary testing with about 1,050 more to go. Then it's another thousand cycles or so to test the various weird combos of mixed batteries. Probably not done until the end of the year.
