Default New Panasonic 18650 High Discharge Cell

Panasonic has released a new NCR18650PD 18650 3.7V 2900mAh Li-ion Rechargeable Battery.

It is capable of 10A discharge @ 20' C.

I think this cell will make the IMR 2000mah cells obsolete.

It has a huge capacity . . . ,

for a high-discharge cell.

Wow! Is there a source for them yet?

i wonder if they can be charged faster too.

Are these better than the AW 18650 protected 3100mah's?

I just spent $20.00 for one of those, and if these are better, cheaper, and comes with TWO, I'm gonna flip...

They are excellent cells, I have had them for a while now and have tested them with others including IMR and these are better under load.

IMO, yes, they are better.

More capacity,

and up to ten amps current capability.

Default Re: New Panasonic 18650 High Discharge Cell

These can almost be thought of as the successor to the esteemed hybrid CGR18650CH.

Anybody with more knowledge than me want to chime in about relative safety features of these as compared to a straight LiMn "safe chemistry" cell?

I have also seen protected versions of these, however they appear to cut out at 7A, rather than the cell's rated 10A

Gotta find a way to rationalize gettin' me some of these....

Default Re: New Panasonic 18650 High Discharge Cell

BShanahan;

A little more info on these cells:

Internal impedance is 22 Milliohms.
(protection circuits will add ~50-60 milliohms)

Eighteen amp pulse discharge capability.

Since these are designed for heavy current capability,

they have eliminated the PTC current limiting device.

This means you MUST eliminate any short circuits.

Okay, I dont understand what all this means for a battery, other than powerful and rechargable, its like a foreign language... could someone help fill me in, batterys for dummies?

Default Re: New Panasonic 18650 High Discharge Cell

Lithium battery technology previous to this cell goes like this:

Option 1 - Li-ion:
High capacity (longer run time) with a lack of discharge ability (cant handle high discharge currents)

Option 2 - Lipo & LiMn:
Low capacity (shorter run time) with a high discharge ability ( can handle high discharge currents)

This new cell has the best of both worlds:
It has a high capacity (longer run times) with a high discharge ability (can handle high discharge currents)

Alternate thinking: a bucket full of water:

Option1:
A bucket that can hold more water but, has a small hole to pour water out of.

Option 2:
A bucket that hold less water but, has a large hole to pour water out of.

New Cell:
A bucket that holds more water AND has a large hole to pour water out of.

Also the internal impedance mentioned is resistance to current flow inside the battery, the lower this is, the less energy gets wasted on heating the battery, it as its often thought of as a resistor, it will limit current flow out of the battery too.

Hope that makes sense to you
