I bro have a quad which can fly with a 11.1v 2200mah lipo battery and 30c rating As I want to make li ion pack that will make my quad to fly Can u pls suggest me which li ion cell should should I use as in ur youtube channel I saw many li ion cells Pls help me building this
Another way to get these battery cells is to buy the m18 12ah battery packs there’s 15 cells in each & I bought 4 new packs for 400$ off Craigslist or OfferUp for a total of 60 21700 cells
Im doing the same with the 12ah M18.. I have a line out on some, hopefully @ 90 each pack if over 10 bought.. I wanna build a 5S20P pack.. the Ultimate 18v battery.. Its for a wicked camping lantern with cree leds that should last up to weeks or months per charge..
I don't recommend those cells, Bosch uses these in core batteries and they fail sooner than expected. I have two 8ah core batteries and both have failed cells in them in less than 3 years of use, the core Bosch batteries are expensive so i was expecting long lasting Life, but unfortunately they disappointed me.
I don´t understand...on the specification of the battery it is clearly stated 70 Gramms, but your battery is only 66-67 Gramms...most probably a fake battery, or just battery from pre-production.
In the specs there is MAX weight mentioned which is useful when designing a battery pack. Actual weight of a cell is always lower than the maximum weight. The battery is genuine 40T.
Hi Matthew! There is no "the best cell" definition because everything depends on the performance/price ratio acceptable for you. You should decide which one at what price is the best for your budget and application.
personally it was the samsung 30T 21700 then the 40T came out but both are very good for mech mods! im about to buy the 40T to put in my new VERT 2 Mech Mod By Unicorn Vapes!!

Have to tested the molicel p42A Cell seems to be similar to this one
"i'v upgraded my battery holder to v3.0"
*is literally a clamp with a couple strips of copper*
made me chuckle a bit.
You expected something "mega-nano-ultra-extra-smart"?)))) Holder should hold)))
It would have been nice to measure the temperature of the battery during the high discharge cycles..any aproximate ideea what it was?
Which one is better for a flashlight? 40T or 50E??
40T is much more capable and runs longer.
should test 35a to see if its can handle and how long
I have 2 brown battery's with the coding: 21865 are they the same size like 21700?
I don't think 21865 refers to the size
@@ThunderheartReviews ha okay...
What os the interal resistane of the battery? My xstar charger reads 23mΩ. Is it normal?
Thank you! Here I can get it for 5,90€. Now I need a new charger, because D4 can not charge 21700 :(
Nitecore D4 can not charge 21700?
@@rahmell05 On paper not but after I get 21700 - yes, you can :/
what is the best battery 21700 for mod single battery i use 40w to 80w dual coil?
Check out Miboxer C4-12 which i've reviewed: ua-cam.com/video/X-ww1YALjvU/v-deo.html
For a larger pack would you choose the Samsung 25S or 40T?
40T
Great video buddy
Thanks Peter!
what chargers do you recommend for this battery?
Miboxer C4-12 would do very well. Check out my review: ua-cam.com/video/X-ww1YALjvU/v-deo.html
opus bt c3100 does 21700
Hi
Can you do a test about the 20700 sayno
Thank you
Is it good for fpv drones
Ive got some of these batterys .when i put the metre on em they say there 5v..whats the deal with that?
Your charger is a crap. It overcharges the cells and kills them.
Hmmmmm why is there some t40 saying max outchage 25amps i cant fint a 35 amps t40

Use lipo to have lower weight
I think Samsung 40T is better than VTC6?
Better in what? Performance, cycle life, price?
Thunderheart Reviews performance
I'll give you an answer when i test VTC6
Thunderheart Reviews yes please do vt6 test
ho do you compare these cells to the genuine A123 ones ?
what is the round cell with higher current draw on earth ?
Its good for electronic mods?
Yes
Can i charge it directly from the mod?

Hi , were have you buy the battery tester ? How much it cost ? useful video , thank you !!! 👍👍👍
Hi. I've bought it on alibaba a long time ago. Check it out for actual price.
@@ThunderheartReviews Thanks a lot for the answer👍👍👍😀😀
how to log the data? and which tester did you get?
Watch the video, there is everything about my equipment and testing method.
Can you tell, this battery comes in which laptop
They don't come in laptop batteries
Whare can i get in india
No Amazon store? ..Bummer
I don't sell them neither on Amazon, nor on other platforms.
Can i use a pair as a rc battery would it be good?
What voltage and amperage do you need?
Can i use it in vape mods?
Yes they're what many are using for vaping, up to about 75 watts per cell. But the Molicel P42A is better.
Not according to the manufacturer, so try to keep it below 80% max discharge

I have two 8ah core batteries and both have failed cells in them in less than 3 years of use, the core Bosch batteries are expensive so i was expecting long lasting Life, but unfortunately they disappointed me.
Have them myself, they have a great lifetime still after 2 years. I never charge them over 80% so they will probably last another 15-20 years.
Samsung 21700 40T vs. Sony 21700 C6A
nice..
Those wires are very thin
Loool))

This is a 20a cell
No. This is a 35A or 45A with 80°C temperature cut. Look in its datasheet.

What’s the best 21700 to run on a mech??
Hi Matthew! There is no "the best cell" definition because everything depends on the performance/price ratio acceptable for you. You should decide which one at what price is the best for your budget and application.
that depends on the ohm's of the coil(s) you are going to use it with.. there are online calculators to figure this out..
