Like I said it was a guess. I guess I.was wrong. Maybe I based it on his primitive setup and miss the 600 watt part

also keep in mind batteries do not charge at same speed thru entire charging process, last 20% are the longest.
As E Musk explained once, a battery is a parking lot, when it is empty cars go in and park fast but as spots are filling up, it takes longer to drive around and find an available spot. So from 30% to 50% it will charge faster than from 80% to 100%
My charger can literally be configured to charge at 20A, obviously with the appropriate cables and power supply, which, as I mentioned, is 24V and 600W.
You could use a similar analogy for tabless Cells versus the standard cell. With the tabless cell being a six-lane highway. More flow, less traffic and less resistance. The standard cell being a two-lane highway. Clutter, higher resistance.
After reading up about tabless cells thatâs the best way that I can creatively put it in my own words.
Thereâs tons of people on here who know more about batteries and electronics than I do. My uncle, my cousin my brother are/ were engineers.
My gift is to creatively process my lifeâs experiences( Philosophical quotes/ Poems) and putting them into words. Iâm coming up on 66 . Probably older than 90 to 95% of the people on here.
In Regards to gaining knowledge about batteries. HKJ and mooch have helped me the most.
Iâve been working on this my whole life! Iâm very thorough, however the information always seems to come by piecemeal.
Tabless Cells. I have about 15 to 20 of them. 21700âs. Mostly Tenpower 50 GX, Eve 50 Pl, Ampace JP50P1 and Reliance RS50.
So far so good.
We all get those emails because these companies want us to review their product. We get them in a few days to a few weeks. After praising one of them years ago I learned not to say that much. Basically so far so good get back to me in 6 months or a year. We have no way of knowing about its longevity until time passes by and the use continues.
Molicel is a popular and pretty good brand. However,in my experience, the P26A was not.
I bought two sets of four. One after the other. The first set was 20 months old with like 110 Cycles lost 22% capacity. Second set was 21 months old about 125 Cycles and lost 24% capacity.
The other Molicels worked good..P30B, P42A, P45B.ect.
I have had many Samsung 50S, Sony VTC5D.. my two favorites that were 3 plus years old, 300+ cycles and only had a 5% to 10% capacity loss. Time for a napâ
. I get up between 3:00 and 3:30 a.m. everyday by choice.
good night.
Personally, I always prefer to use perfectly matching batteries, so exact same brand/model, same nr. of cycles on them and possibly bought at the same time/from the same batch, when used in series in a flashlight. This is due to the (somewhat) higher risk of Li-ion batteries in series and certainly due to the fact that the batteries arenât balanced charged in a flashlight/configuration like this, making it even more important that the cells even match more closely.
The fire/explosion hazard of 2 (high power) 18650 or 21700 batteries is not something I would like to experience, but the total amount of energy/power stored in 2 46950s is on another level.
So no, I personally would not use those 2 batteries together in the same flashlight!
By the way: those 2 Lumintop batteries on the photo (the orange/black version) have âmodifiedâ/raised positive terminals and are slightly longer than the white Lumintop or the EVE 46950s, so you might run into contact issues with other 46950s.
Both the Lumintop and EVE 46950s have non-ferrous/non-magnetic positive terminals, so magnets wonât work in this case. There are several (affordable) battery holder options on Aliexpress, that fit 46950 batteries and can be quite easily being modified into battery charging holders. (I personally have bought one for that specific reason.)
Damn, thatâs a good one! I never thought of them being used (or able) for charging 1S Li-ion batteries; in the back of my mind I always automatically connected them with (specificly) charging multi cell LiPo configurations.
I just checked several of these chargers, including the ones from ISDT and there are really interesting options for charging 46950 Li-ions!
Iâm certainly going to look into the different options and possibly pick one up for my 46950s!
A bit confused about your long post. Where did I say that I mixed batteries and didnât use the same brand etc etc. The only reason I mention it is because the quote was directed towards me. Wasnât a general comment.
If theyâre not magnetic, thatâs not a major problem either. You can make a battery holder or adapt an existing one, as needed
I reacted on this post you tagged me in:
In that, you asked me the following question:
I (mistakingly) assumed that you considered using the EVE you already had in combination/series with Liitokala 4695E you had (or going to) purchase seperately.
Even if both are the same type/model of EVE batteries, the fact is that they are not perfectly matching cells, possibly being slightly different grades, different production dates/age, different storage conditions and slightly different in the amount of use/cycles they both have had. All of this factors in, when using both of them (unbalanced) in series in the Mach 3.0. The best option to have the highest chance of closely matching cells on all those factors, is buying 2 completely new cells, from the same store/vendor, at the same time so that there is (in theory) as little possible difference as possible.
I now realize that (technically) you specificly asked if they would together in the Mach 3.0, not if it was a good idea or not. So Iâm very sorry that made a false assumption/interpeted your question incorrectly!
I did partially answer your actual question though, by mentioning this:
This means that there is a possibility that the Liitokala and/or your EVE, when used back to back in the Mach 3.0, might not make good or reliable contact, so Iâm not sure if it would work.
For now Iâve put in more than enough time in providing photos/information/answers (in this topic and via DM) over the past 24 hours, so Iâm taking a break and going to enjoy my weekendâŚ

Be careful. Those raw batteries you bought from AliExpress donât have any insulation and they might not have the exact same terminals which could create sparks and a fire or thermal hazard. Also, they donât have over charge protection so they could catch fire if the device thatâs charging it itself doesnât have overcharge protection
Is there any reason you bought the mach 4695 over the GT 4695 pro
I am sorry I bought any 46950 flashlight off of Lumintop. First of all Iâm a throw guy not a flood guy. More importantly they sell you a light and they donât provide a replacement battery telling me that it must be in a flashlight and international law blah blah blah. Then we can buy them from other places and they sell it individually, without putting it in flashlight. Maybe itâs a case of greed not safety.? Who knows?
Now youâre telling me that the blue battery from AliExpress may be unsafe.
I think Iâll just throw it off the Douglasville Bridge into the Schuylkill River in about an hour or so on my 4:00 a.m. hike.
I donât have enough knowledge about this stuff to know what is true and untrue.
Iâve discharged the blue battery from Eve 5 times in the Lumintop Mach
Iâve charged it five times with my Anker 65W fast charger. I believe it has all the safety protection features.No issues. That doesnât make me comfortable with this blue battery. See Anker specs below.
Type in 46950 power bank charger in AliExpress itâs much better and plus you have a power bank. Whatâs in the picture? Is it just a regular multiport? Are u just charging the raw battery thru ur flashlight ?
1 Thank
This is all u need:
Just put insulation around the battery and it will be safe but donât charge the raw battery inside flashlight they donât have over discharge protection so you can only use your regular battery for charging in the flashlight and if you want to charge your raw 4695 battery or any other battery use these products
I just found this on AliExpress: | 76HD Aluminum Alloy 46950 Battery Case Quick Charging PowerBank Shell Durability Lightweight Portable Design For Outdoor Use
https://a.aliexpress.com/_mPji9e1
Thx. for the Info.
Yes. Both batteries were charged inside the flashlight. I might sell this again I stopped the sale a couple weeks ago these batteries are a hassle not worth it.
Like I said Iâm not a flood guy anyway.
A light that throws is much more impressive. You got a single 21700 cell light like my modified K1 or my modified L21B and they have over 5,000 lumens and 450 to 550 kcdâ
How long would it take to charge that battery with the charger you sent me a link to. That power bank? I bet you it will take longer. With that than the Anker. it takes five and a half to six hours when the battery is depleted to 3.7/3.6v.
I just thought of something. Shipping cost more than that cheap Chinese power bank!
That Chinese power bank/46950 charger is so cheap it could be more dangerous than charging a bare Eve 46950 in my flashlight!
I think youâre a bit confused. That battery can be charged inside the flashlight just like any other battery in any other flashlight. The flashlightâs controller certainly has protections; itâs common sense, and you donât need anything else to charge it safely. Itâs a different story if you want to charge it externally in less time using a smart charger, as I mentioned before. The only problem youâll have is isolating the bottom of that battery so itâs like the original Lumintop battery and doesnât touch the flashlightâs chassis
