wannaburnstuff;

Their concern is to prevent loose cells from shorting together . . .

and start a fire.

This testing was done in Denmark by "HKJ" who posts over in the Candlepower Forum.

It is a very good study of many current #18650 cells.

It is amazing that the Panasonic 3400mah puts out 5A,

much longer than the high current "IMR" cells.

Update on International shipping:

An inexpensive circuit will be required to ship them internationally.

I have found some very inexpensive equipment to ship the cells in.

I think two cells will ship for $8, in an inexpensive circuit holder.

Three/Four cells will ship for $11, in an inexpensive circuit holder .

Price Decrease . . .

Panasonic 3400mah #18650 cells now $12.95 ,

prepaid in Cont. U.S.

With positive terminal buttons if desired.

Also, Panasonic has released a new high-current cell, the NCR18650PF.

Output current up to 10 amps.

Default Re: Quality #18650 Batteries & Charger

From what I've gathered from net, this is what others are reporting concerning the PF cells. This info. is all copy and paste and did not come from me:

Different chemistry to the PD. LiNiCOMnO2. The PD has Lithium Nickel Cobalt Aluminium core and the PF has a Lithium Nickel Manganese Cobalt Oxide core. The PF chemisty should be better for longer high drain applications and should be less prone to damage over time.

The latest high drain 18650 li-ion cell released by Panasonic!
New generation of NCR18650PD!
Maximum 10A constant discharge current!

1. Minimum Capacity: 2750mAh (0.54A discharge at 20C)
2. Typical Capacity: 2900mAh (0.54A discharge at 20C)
3. Nominal Voltage: 3.6V
4. Discharge End Voltage: 2.5V
5. Standard Charging Current: 1.35A
6. Charging Voltage: 4.200.03V
7. Standard Charging Time: 4.0hours
8. Max. Continuous Discharging Current: 10A
9. Internal Resistance: less than 35mΩ
10. Weight: less than 47.0g

I hate vague information so I contacted orbtronics about it
this is the reply:

'Hi William,
Yes, that's the improved PD. It runs even cooler on high Amps, and improvement on voltage drop. Nothing significant. 30-40 mAh more in capacity as well.'

it just shows that any improvement they can make they will and panasonic is staying busy in the R&D dept

Have you gotten ahold of the PF's yet Larry?

Anyways, Larry is reputable and supporting a member is always a good idea. He only sells genuine cells. +REP for making quality Panasonic cells available to our members

Default Re: Quality #18650 Batteries & Charger

It is interesting that 18650 seems to be where all the "action" is.
I do own 2 pair of the Kongs but only have 1 unit that takes them. Not really into that size of a unit. Just doesn't seem "elegant" once you get that big regardless of output.
I'm only 5'5" and have small hands so that may be a part of it. Do own a 7 D cell maglight from way back when but I would consider the reason to carry it has more to do with it's like holding a baseball bat for protection than carrying a light.
A laser that takes an 18650 generally feels good in the hand for overall size.

Pman;

Thanks for the kind words . . .

I would like to add one important reason I have started offering the Panasonic PF cells: SAFETY

Quote:
Lithium nickel manganese cobalt oxide (NMC) offer lower energy density, but longer lives and inherent safety. Such batteries are widely used for electric tools, medical equipment and other roles. NMC in particular is a leading contender for automotive applications.
More cycle life under heavy load is also a significant benefit.

For applications where the high capacity is important,

the 3400 mah Panasonic cells are back in stock.

With all the shipments being returned, cells are in short supply still.

LarryDFW

P.S. Also have some 2900 mah hi-current cells available.

Are these normal 4.2V cells?

Is there any additional cost for shipping to Canada?

The specs would seem to indicate a Panasonic cell.

If so, @ $21, it is still too expensive for a 3400mah cell with a protection FET.

Placed an order for 4 cells on 4/30/14, with the positive terminal added.
Can't wait to get them.

Added some Panasonic cells capable of 10 amp continuous output.

These would be good for high current demand lasers & lights.

Capacity is high @ 2900 mah for a power cell.

Hey Larry, haven't heard from you. Any update on my order? Is it pending or shipping?
