Wonderful comparison video, Sir. As I'm shopping for my first e-bike battery pack. The included chargers are rated at 2 Amps. I'm still not sure, but it seems as though that's too high, unless the charge is divided by the Parallel number. Is that a good guess? "Panasonic 18650GA 3450 mAh Cells Configuration: 13S4P". It still seems high, especially for some of the batteries. I want them to have longevity more than quick charging.

Great review! Curious to know... which 18650 has the best/lowest storage discharge rate(?)

Excellent video! Thank you. 👍

Thanks Dan! :)

You even made the same comment twice :p ;-)

And you don't love timetables located in the very first comment, right?))

Me too:)

Absolutely right. And 13A for non continuous discharge.

They are different generations. It's ild video. These are different 35es

Thanks Chris! Unfortunately I don't have accurate enough equipment for measuring the internal resistance. I'll receive my new scale with 0.1g accuracy and i'll add weight info in future tests. Cycle life is impossible to test for me because of lack of time. Information about cycle life is usually (but not always) available in datasheets. I'll add links to them later. Thanks for useful feedback! It helps me to make my reviews better:)

I'm looking to get 1400 hi capicity for off grid battery, what you recommend?

NCR18650GA is the best, no matter made in China or Japan, but it would be costy to buy 1400 of them. Maybe you'd better to look at 3000mAh/3A batteries like QB18650-3000? It would save almost 50% of your money. Tell me what are your requirements for the cells.

the batteries are for me and a like minded friend. He wants about 500. Mine is for off grid storage for a 1kw pv array, to run lights, fridge, tools etc Currently using 16, 120ah lead acid 12v, arranged as 2 banks @ 24v. They need replacement. Fridge draws 1.1kw daily. Biggest tool takes 1.5kw.

You can easily use cheaper 3000mAh QB batteries arranged in series of 6 (6S pack) to provide 3.7x6=22.2V nominal voltage. The charge end voltage will be 4.2x6=25.2V in this case.

I'm gonna test 3600mAh cells soon. So keep tuned ;)

Hey this is a late reply but did you settle on a cell cause im in the same boat as you now?

@@a-aron2276 You will have to calculate the maximum drain of the motor and the battery setup ;-)

but look at k2 26650p (completely different battery but you will never have problems at high load)

@@digitalizations well im not going for 8kw im only going for 3kw, 70kmh is all im looking for, so im going for a 14s 9p pack from the Samsung 35e cells, which litterally arrived last night.

This is by no means my first go around, this my fourth build, i was more wondering which cells held up better in real world conditions, high drain at around 15°c, so i chose the 35e because of their higher end voltage, e.g. lower current for the same power on the low end,

Great))

Be aware, Liitokala cells have higher internal resistance, higher self-discharge over time, and lower cycle life as compared to a genuine cell. The reviews on AliExpress using Liitokala charger may show the rated capacity, but this test is performed at very low discharge current and useless for determining capacity under typical usage. I purchased Liitokala 30Q cells in Apr 2019 to make a 14s5p ebike battery back. It is now Jul 2019. After only 4 months with an estimated 6-7 cycles a week, charging at 5.67 ampere and never discharging below 3.0 volt per cell, the capacity of the battery pack has suffered greatly. The pack voltage after charge is only 56.4 volt versus 58.8 volt when first built. The BMS stops charging prematurely because one of the cells reaches max voltage faster than the others. You get what you pay for, ultimately.

@@lxndrskv balancing the cells would fix that

@@motohead077 hmm, I should try that.

@@lxndrskv Assuming that you tested the cells individually before building the pack, to make sure they are compatible to use in the same battery pack. If not, 1 or more of the cells could perform too much different than the others & cause issues like this.

Depends on the best in what))) When you look at cycle life or max discharge rate they are far from being the best. Say a cheaper 3000mAh cell after some 300 cycles could have a higher capacity than one of those. So which one is better?

@@ThunderheartReviews ls there such option? A cheaper 3000mah cell that degrades slower than those in the video?

@@tnig take a look at Samsung 33J kzfaq.info/get/bejne/bax9q8p-0rbJmGg.html

Hi Ron. Take a closer look.

@@ThunderheartReviews ohh, I see what you mean. Yep my bad. Thanks.

Thanks Daniel!

During the tests each battery did about 10-15 cycles. It's too little to talk about any capacity drop. All 4 are great cells but i'd prefer Sanyo/Panasonic

Thunderheart Reviews It appears that LG cells degrade less than Sanyo/Panasonic. I saw that in the datasheets it's several hundred cycles more on LG than S/P before reaching 80% of the original capacity. It'd be great to have some kind of test on such claims.

Hi Mike! Unfortunately i can't test the cycle life to confirm or refute the official data

The thing is, the cells will degrade simply from age as well, so you would have to test a cell after 2 years of non-use and the same cell at different rates of usage. And copy those tests on other cells as well. Then you would have a somewhat accurate result.

Depends on your flashlight's power requirements

Yeah, all the top manufacturers' technologies have almost reached the limit.

@@ThunderheartReviews thats fair. hey keep up the good work! mate, your channel is excellent. we need thoroughness like this and you're a champ.

Thanks:)

Thanks Miguel!

Nop, none of them, if you want a protected, look for the panasonic NCR18650b, just make sure that the one you buy has the protection, because it is sold both protected and unprotected

What discharge current you gonna apply?

Thunderheart Reviews I have a drone lipo battery is 7.4v 25C 1800mah I wan mod the battery

Try to make a 2S2P pack from Sony VTC4 cells. The test is on my chennel

Thunderheart Reviews sony vtc6 3000mah or panasonic NCR18650B 3400mah how about them?

NCR18650B is a low-drain cell

No. Sanyo doesn't make batteries wrapped in Panasonic-style shrinks.

Thunderheart Reviews so it is a Panasonic I suppose. Thanks.

Yeah, it's a Panasonic cell made in Japan. Panasonic has its factories both in Japan and in China.

What's your problem?

Which tester did you use?

Myself, a known resistor and a MyDAQ. The method is reasonably accurate, so I don't think it could be 40mOhms of. But back to my question, if I would get the mentioned results with the perfect meter, would you say they are fake cells?

Maybe not fake but used ones. 80mOhm is too much for a new cell.

Inspironator I bought a couple.over the internet, hope they are authentic high drain and work in a vaporizer

Capacity is the amount of energy a cell gives at discharge. There is no "charge capacity".

@@ThunderheartReviews when finish the battery capacity after i will charge with usb tester what will be there different of discharge

Sorry, i don't understand your question

@@ThunderheartReviews for example i have powerbank when i charged this item whic takes 20000mah but gives just 13500

Its working %65

8A is the limit for 35E. You can use 35E for vaping though i'd recommend to choose something which can provide higher discharge current like LG HG2

Thunderheart Reviews thanks, i already use HG2, but 3000mah is too small for me. Anyway thanks for tests

Then your choice must be Sanyo or Panasonic NCR18650GA. Japanese made NCR18650GAs are the best.

Thunderheart Reviews yes, but its with protection board, they are too big for boxmod

All four batteries in the test are without protection PCB

Depends on what you need.

@@ThunderheartReviews your replied is as if you did not answer at all....... We are seeking great help from you and yet nevertheless, we are severely disappointed with your useless replied

@@snowy2875 There is an XXL size coat of black color and an XL size one of gray color. Which one should i buy? This is how your question sounds. How can i tell you what to buy without knowing your requirements?

@@snowy2875 i ca-n see that you are frustrated but that answer it’s ok . What is the battery for is more important than capacity but you seems that you don’t have any knowledge about discharge rate . How many amps drain is needed? If you need a better answer you must ask a proper question . Both batteries are good and depends on what application is use for . Nothing wrong about first answer with a bad question .

Вы про Liquid-free?

Thunderheart Reviews про суперкондеры :)

Нормально обстоят:))

кстати, а toshiba в формате 18650 аккумы не делает? или они не из ряда доступных?

Я таких не встречал

A123 ones are American. Well, the technology at least)))

Price differs from supplier to supplier. If i mention the prices some would come with "you lie! they are a whole dollar more expensive/cheap!"

@@ThunderheartReviews of course prices differ from supplier to supplier but LG is consistently cheaper from every supplier. you have an answer for everything, sometimes you just gotta adjust the way you do your videos. good video anyways.

Bonjour Alain! Nkon is a good store but their prices are the highest i've ever seen:) So it's bizarre to hear that ordering from China is more expensive than buying at Nkon... Whatever, Nkon too sells genuine cells and that's the most important! Salut!

Really?:)

nope you need play more with cell. LG MJ1 3500mAh tested with Opus C3100 in test mode, resulting 3505mAh (46,75gr) & 3521mAh (46,85gr). but only great at lower than 5A cont discharge

I want

Really?!

Are you new battery God?

Hi John! Happy to read that! More reviews of new models are coming - stay tuned ;)
