what do you use it for?

>>1086457
Fucking everything.

Rip apart a power tool power pack? 18650's.

Cheap Chinese electricals? 18650's.

Power banks? 18650's.

>NCR
Just to note...
been a while since I've had to buy batteries but IIRC that's not a good battery chemistry to be holding up to your face for vaping.

Some have LiPo.

It's brilliant how cheap they are. I repaired a £120 power tool battery with £20 worth of18650s

Laptop batteries?

Even the Tesla Model S battery pack?

186-goddamn-50s

>>1086526
dude, the battery is only 10A, those would pop so quick

>>1086458
electric cars

>>1086558
It's a momentary demand, the thermal inertia of the cell helps.

>>1086564

Use LiPo, burn your face off instead of blow your head up.

>>1085856
LG ones are far superior.

>>1086458
They need balance boards and a bms if you want to build any large battery bank with them. The cells tend to drift a lot.

>>1086526
I have been wondering if i could use recycled 18650's in my e-cigarette. as you can get them in pretty much everything. any ideas if it would be safe to use them? do they all come with protective circuits?

>>1086560
The problem with electric cars is they don't go very fast or very far, and if you drive one people will think that you're gay.

>>1087057
>Implying a Tesla model s p1000d isn't fast as fuck
You're just jelly you can't into electric tech

>>1087072
Looks like you can't into Simpsons references.

The line was from an oil company's electric car amusement ride.

>>1087072
sure its fast, for about 50 miles if youre matting the pedal

>>1086543
Laptop batteries are increasingly lithium polymer, not liquid-electrolyte round cells.

Slow your roll there Autismo Musk, he wasn't disputing you, but actually referencing a bit of pop culture from the recent past! In fact the reference he made was to a cartoon bit making fun of those decrying electric cars!

uhh, is this secretly a vape thread?
THE POWER! CURRENTly VAPING THROUGH TIME AND SPACE RN

you choose battery packs based on the cheapest thing that will meet your life and usage demands. you can get lifepo4 flat cells for about 60$ that will stand up to 100A discharge for its 5y limit and only lose 20% of the capacity.

question is, vapefag, did you get a genuine cell?

>>1087054
considering it's going to be in your pocket a lot, I wouldn't chance it.

PSA: If you find 18650's claiming more than 4400mAh they are fake.

>>1089947
I haven't seen one from a reputable brand claiming more than 3.5 Ah

>>1086573
https://hobbyking.com/en_us/turnigy-nano-tech-ultimate-4600mah-2s2p-90c-hardcase-lipo-short-pack-roar-brca-approved.html

up to 90 amps continuous

>>1090130
Actually, it's not 90 amps, it's 90C, and since C is 4.6 AH, it's actually rated for 414 amps!

>>1090167
jesus fuck nigga thats more than enough to start a car

so much faggotry in one place

>>1090268
Indeed. It's not even the biggest they have, either.
There's also a 7.5Ah one (675 A).

>>1090130
The price you pay for that is a lower energy density
compared to a high energy 18650 cell,
~0.25 Wh/g versus ~0.15 Wh/g

>>1090167
cloud chasing taken to whole another level

>>1090268
That's because they're for RC cars.

I have that exact battery in a Tamiya kit, thing fucking rips.

>>1087054
No, most ones from tools, battery packs ect don't have the amperage needed and will blow the Fuck up in your face

Any ideas on how to get 1000's of them with free shipping? like those obsolete laptop batteries guys use in youtube videos

Who are reliable suppliers for a good price?

What is this C thing? Never heard of it before.

>>1094028
It's the capacity of the battery, and is typically used as a multiplier to specify max current.

In other words, if you have a 1 amp hour battery that is rated to discharge at 5C max, that means you should draw no more than 5 amps. If you also had a 5 amp hour battery, also rated at 5C, then you could draw 25 amps, and so on.

A charge or discharge rate of 1C will always charge/discharge the battery in one hour (plus or minus any inaccuracies and loss of energy due to inefficiency) because it is 1 x the capacity of the battery in amp hours, 2C is 2 x capacity = 30 minutes, 3C is 3 x capacity so 20 minutes...

If you need more info, just google "battery c rating".

>>1094028
>>1094054
Err, I misspoke slightly.
It's not the capacity of the battery, it's the max current, specified as a multiplier of the capacity.
