Why not test American made batteries??? Just kiddin'. But, really a shame everything is off shore now.

Are you okay? You are gone for 2 years

Guys LiFePO4 is considered as 100% charged at 3.4V(Resting state). The video shows 3.34V, which is still above 90% charged if you are nitpicking.

Is it possible to connect these as a 19.2v 6S1P? You can find 3.2v BMS but then I don't know how to get that nicely into a tool battery shell. Would be amazing to create a 2500mah 70A CDR unit.

3.34 V is not fully charged!

Great video - I would have loved to see the Panasonic NCR18650B cells tested as well

I would like the see the discharge curve @100 milliamps. I think you would have reached the full 900 mAh, at close to 3.5 watt hours! (regulated LED flashlight) Finally...A14500 cell that actually produces its advertised capacity!

helo man! u have this qb still? i see your site too??

Hi,could you teach me how to check The original (not fake) for Panasonic NCR18650BD

🤔 Can u open up the wrapper LG Cell 21700🤔

😢Can u unrap the LG M50T & video have ! Is it Rought metal Surface or very Shining Surface!!😊

UR14500AC US14500VR2 comparison?

Those wires are very thin

''.com.cn'' means canada or china?

Who the F stands in front of an open chamber while doing a nail penetration test.....?? Moron!

Por AliExpress no venden ?

How does the lishen 2170la stack up to the 50g ? I can't find any comparison. Which would you go with ?

Very clear review, i have the vp4l that can fit protected batteries

Can we use deionized water to cool lto battery?

Very Nice!

and the mnke can be rated as 30a max cont dich?

This isnt available anywhere to buy

Сижу заряжаю. И вдруг, как раз сегодня решил залезть в интернет, посмотреть, что есть на данную тему. Никогда не интересовался, хотя свои купил году может 10 или 11, точно уже не помню, короче давно. Маркировка другая, как на оболочке, так и под ней (просвечивает), штрихкод опять же под оболочкой. Никаких корзин. Краска вокруг минуса нанесена под оболочку и чуть выступает.

real professional test, why isn't there a delay on the nail going straight down

Good morning, do you know the difference between 21700-50G and 21700-50 GB. Thanks in advance.

I noticed this one. Please teach to me Sir. Why did result mah is same even discharged current is different.

I wonder if it charges faster than the LG HG2 tho 🤔🤔🤔

The old ones were 25 amp these new ones are some 20 amp bootleg

These are out of stock all over. Any idea when they will restock?

should test 35a to see if its can handle and how long

Is it good for fpv drones

The fact that your Grade A/B testing showed such a difference is proof that testing single samples is unreliable.....or you have no idea what you are buying. Both are similar enough to say you could be buying two Grade B. And then it also goes to show that ratings of some of these cells from QB.....are random to say the least. 2300 cell- more capacity less power 2500 cell- less capacity more power The exact opposite of how its supposed to work. Unless you mixed up the samples but if the wrap is labeled....

Hello Thunderheart Reviews, could I please use a few seconds of this footage for my next youtube video? If ys, of course I would give credit to your channel! :) Best, Tom

Many if not nearly all Lifepo4 react this way. Some have a little steam, some dont care even after multiple penetration and just keeps working. Love LiFePo!!

I don’t know if you will see his, but I’m wanting the lumintop d3 it runs on 26800 and 21700. If I run a 21700 with the same or higher rated watts will it be as bright, or will the less internal resistance of the bigger cell give it a upper hand. I can’t find a 26800 so I have molicell p45b and also 40t, but idk if it’s worth to find a 26800 or if all it does is increase runtime.

Wait so what is the difference between 50g and 50e ? The datasheet looks almost identical ? Edit. 50G has more number of charge cycles before losing capacity. Anyway 50G is either unavailable or twice the price of 50E in my country, so it seems to be worth it to just go for 50E.

All 26650 batteries contain a 18650 cell inside the case.

test is stupid. nmc was at full charge while lifepo was at low charge. 3.34 for life po is anywhere from 25% to 75% soc, so there is no way to accept this test as valid. lifepo should have been 3.45 or above for testing purpose. anyone who knows lifepo would know this, so my guess is they are banking on most not knowing this fact. i hate those who chose to deceive by only shearing half the story.

One battery full of energy, and one almost drained. GOOD TEST. RUN FOREST, RUN!!!!

Pure copper oxidises and creates resistance (adds voltage drop). That’s why you shouldn’t use bare copper connectors. 4 wire connection is so you don’t need mega thick copper wires and connectors - you seem to have not understood that. It looks awkward to load batteries.

Should I use these batteries for a 6s2p pack for 7" drone ? I calculated the weight = 840g. Where the 18650 @6s2p = 528g. That's 312g more if I use the 21700. Which one you think I should use ?

This is a fake cell not genuine

What os the interal resistane of the battery? My xstar charger reads 23mΩ. Is it normal?

not bad

Having trouble finding LGDAHB61865 battery. Seems these LG batteries are hard to find for the consumer. I took apart my Milwaukee M12 CP battery pack and these were inside. One was reading zero volts. The other 2 were good. Tried bring back the single cell on my power supply but to no avail. Any help on ordering a few of these would be greatly appreciated.

If you scan the code you will get the batch/lot # which is also the mfg date.

I can’t wait. I ordered a 52v battery using the LG 21700 cell.

Hi. How you did this chart at 3:24? Excel or other software?
