Is there any 3000-4000 mah Battery’s that can safely continuously discharge 20Amps. Trying to build a 48v Ebike Battery and want to make sure I use the batteries that will give me the longest range possible for the bike. I’m thinking of doing a 48v 14ah pack. How many Cells would I need?

Top 3 categories:
We can categorize the best 18650 batteries by things like high-energy (Wh), high-power (A), or high-capacity (mAh).

Other considerations:
There are also things like safety standards, your application, environment, and so forth which will dictate which cell is best for you.

Availability:
One important factor that people overlook is production availability. Many cells simply are not currently in production so any stock you buy will be old. It’s best to buy whats in production, now.

If we just take a balanced look at cells, here is what I think are the best cells at the moment (posted March 2016).

LG Chem HG2
3000mAh, 20A

LG Chem HE2 / HE4
2500mAh, 20A
*Note, the HE4 is better with handling heat, and also only needs to be discharged to 2.5V to reach its maximum capacity, while the HE2 needs 2.0V.

Samsung 25R5
2500mAh, 20A
*Note, the blue 25R is no longer in production, always buy the green 25R5

These cells are primarily high-power cells (amperage).

If you are maximizing for capacity, there are other cells you may consider. I know many people reading this post are e-cigarette / vape users. Actually it is a myth that your battery needs to be “super-amped”. In many situations, especially with dual-battery mods where the amperage is multiplied, you only need 10A cells to product significant “clouds”.

The other nice thing about high-capacity cells, is that generally they have a longer cycle life. You can also put protective circuitry directly on low-amp cells (less than 6 amps generally).

So here are the best high-capacity 18650s:

LG MJ1
3500 mAh, 10A

Samsung 35-E
3500 mAh, 10.5A

Panasonic B
3400 mAh, 4.5A

If you are really interested in high-power cells, with a high maximum continuous discharge rating, then take a look at this cell:

LG HB4
1500 mAh, 30A

There are many “fake” or counterfeit cells with high amp ratings that exceed 30 amps. That is impossible, no 18650 cell on the market has a rating above 3000mAh.

I hope this helped you find the best cell! All the models I mentioned in this list are currently available and in-production by LG, Panasonic, and Samsung.

1/10 troll Everything Anti_Scam said was wrong. Yes fake batteries from China with inflated stats flood the market, but no, these are FUNKING SONY brand.

The link you provided despite the FALSE title is not for the Sony Brand but rather a knock-off 2Pcs GOODFIRE Brand… This would lead one to believe you are affiliated with this brand and deliberately posted a false link. If not poor judgment was used in providing the link. Anyone purchasing the fakes whilst following your link is not going to be impressed with the GoodFire brand as they are well known to be of inferior quality, providing false maH ratings. Click on the picture, it clearly shows the true brand of these batteries.
