Trusted battery seller?


#1

I’m looking around now for 18650 batteries, and hear Samsung ones are pretty neat, and are a good way to go. I saw these on Aliexpress for a pretty decent price (8 pieces fo 20 USD) but thought it may be too good to be true. Are these sketchy?

Link to check it our yourself: http://www.aliexpress.com/item/8PCS-lot-New-Original-Samsung-18650-ICR18650-26F-2600mAh-Li-ion-3-7v-Battery-Free-Shipping/32609856540.html?spm=2114.40010208.4.2.vB3NOY

If these are dodgy, where do you guys recommend me buying bulk for relatively cheap, I have $400 to spend on batteries for a Bigfoot 160 monodrive build.

Edit: I’m located in Australia, if that helps.

Liionwarehouse if you are in US. I am going to get my cells from FastTech (I am in Australia) they have good reviews but the cells ship by boat so it takes like 1-2 months.


#3

they look pretty legit always read the comments and especially the negative. The more comments the more purchases have been made for the product


#4

If i remember correctly, the green 25r is better? Forgot why, perhaps increase life cycle…forgot, you can look it up.


#5

I too am in Australia. So I might check them out

Edit: Forgot to ask, are they cheapish? I’m on mobile and not enough time to check right now. I have around $400 AUD to spend on batteries, hoping to have a little bit left maybe a bit less than $100 to spend on enclosures and extra bits.

5.2A discharge rate. Wouldn’t be suitable for eskate unless you had about 10 in parallel, so you’ll probably want to look for a different cell. Also, I wouldn’t trust the legitimacy of alibaba products, but that’s just me. Try the Samsung 25R like Enertion uses.


#7

Last time I checked ( and that was a LONG time ago)enertion uses (used) LG 's.

My information could be outdated


#8

At about 41 seconds


#9

Looks like he upgraded! Good choice


#10

Oh crap, I just realized those are not even 25Rs lol, I meant to compare the green and blue 25Rs


#11

So I should go with the Samsung 25R ones?

I’m looking at the Liionwholesale site, it’s around $4 for 40 batteries, which is how many I intend to get.

EDIT: doesn’t ship to Australia, but I can find one that does, but basically, that battery is the one to go yes?


#12

That is the one yes. I was just about to say that they don’t ship to Australia.


#13

You mentioned you were getting it from FastTech? When I check out it says Australian Expedited Air or something? 9 days in transit, or something along those lines? No option for shipmail, unless that was the one.


#14

I looked at it a while ago. I think they do have faster shipping yes.


#15

can’t go wrong with 25r’s, but there are other great cells out there too, look around


#16

how many cycles do li ion get again?


#17

I have ordered hundreds of cells from them and every single one has checked out. Not a single dud. The more you buy the less they cost there too.

Also they don’t waste time getting them to you. You’ll probably have them in a week.

I use the Samsung INR18650-25Rs because they’re basically made for our applications at a 20 amp continuous rating and a 100 amp burst which is ludicrous.


#18

why not get the LG cells?

~20% more capacity, negligible price difference, similar discharge - am I missing something?

#19

I don’t think the price difference is negligible it’s like 80 cents which is big deal when buying a few hundred at a time as some of us do


#20

You’re right - I was thinking the price difference was $4.69 vs. $4.91 but I went back and looked and it’s $4.69 vs. $5.91, a ~20% difference.

So in terms of capacity per dollar it’s almost exactly the same, but still I misread.
