32600 3.7V 5000mAh D Li-ion Cells

[LEDite]

Anybody notice these new Li-Ion D cells?

10 Amp Discharge. Should give long run times.

Don't know what the black negative terminal is. Maybe a cover.

$15.50 each; not a bad price for a limited production cell type.

May have to work on a new multiple Cree head. Anybody have a 1 D-cell body ? Maybe a 3-AA cell body might work.

I've ordered the battery to try out.

Hello Larry,

Interesting...

I believe the black is simply a play of light on the bottom of the cell. It looks to me that the negative is simply the bottom of the can.

They look like unprotected cell, not safe to use in multi-cell application.

Correct me if I am wrong.

Nice find... but if the batts plasmaman are checking out really turn out to be 7200mah, I'll go for those 😀

I wish I would have seen these a few days ago:mecry:

Great find.

Wow, I hope the protected version isn't far behind . . . .

Any suggestions for charging these?

 

[Fallingwater]

I'd say use a RC charger. Anything else probably doesn't have the power to throw five amp-hours in them with reasonable speed.

I must say, having these behemoths around would make me a bit uneasy...

They can also work as hand grenades if you're not careful. I would not recommend these to anyone without a little education on Li-ions. Last thing we need is some uneducated/uninformed who gets injured with one of these and then we won't be able to get them anymore.

Don't worry about some fool making them unavailable. If any of them explode the seller is pretty much untouchable. The responsibility will fall on the importer i.e. the person who placed the order. Just don't try ordering a bunch with the intent of reselling.

Jay T;

If they are properly designed, they should be equal in safety to the 2400mah #18650 lithium cells in wide use today.

The capacity is ~ double and the weight is ~ double.

This would allow for the same heat impulse capacity as the #18650 smaller cells.

These cells sound interesting and deserve another look especially if Plasmaman's 7200mah Li-ion cells deal fizzles out.

Now we have another contender.

I still like the D-cell form factor better and the capacity of the bigger cell may be more realistic..

Hey Guys,

I got some info from a supplier for 32650 cells 5000 mAh, but am in no way a guru on this stuff, so I don't know what spec. we need our PCB to be. I need some help here so I can reply to the wholesaler and get some pricing.

Here is the info I received:



HI, Good morning.

Thanks for your kindly inquiry for our ICR32650.

First of all, It is high discharge rate Li-Ion Rechargeable Battery. and the dimension is the similar like "D" Size. The dimension is 32mm(diameter)*65mm(Height). The Capacity is 5000mAh. It can be installed PCB according to the customers' requirement. The PCB can be Protect the battery from Short Circuit, Over Charge, and Over discharge.


The detail information of our those Column Lithium Ion Batteries is given blow for your ref:

Sir, If it is possible, May i know your estimate quantity on this? Then i can give your the exactly price for your ref/

Anything i can do for you, Just let me know freely.

That ICR50360 is amazing!

Bigger than a No6/Flag cell, and 50Ah!

Able to regularly deliver 150A. It must be a traction battery.

Sorry to hijack this thread, but ever since the 1890s, we have been looking to find a more energy-dense battery than the flooded lead-acid cell, that produces a useable amount of power.

It looks like at last we might have found it.

Maybe, just maybe, this might cause NiCad F cells to be dumped onto the market a bit cheaper.

No way in hell that's a five amp-hour cell. More like 3 to 3.3.

I want a 50360! 😀

Or maybe not, think of the disaster if that one blows up 😛

I just ordered this cell so I can give you a back to back test.......

We're all waiting 😉

I tested both the D and C size - at 5A draw the D (32600) size still gave around 4300mah which seems pretty good for a low cost cell (especially compared to their 5000mah rating).

Cannot remember the current draw on the C (25500) size but they rated around 3000mah (which about what I expected - certainly nothing near the 5000mah they are rated at).
