Li-ion pack differences

[Darth Animus]

Hi guys, just had a quick question.

What are the main differences between the 18650 pack and the 14500 pack? Obviously the run times will be different, and one the one is a larger size, but is there anything else to consider?

You hit the highlights.

Thanks, I always get a little nervous when the answer seems too simple, haha

I was wondering do they discharge the same current? There's a PCB in the store that says it prevents the battery from discharging more then 7A. Do the 18500 7.4v packs discharge this high?

They both have the PCB built in. you only need that if it specifically does not say "PCB Protected" in the part description.

Neither of them discharge that high.

I understand they do not need to be PCB . I'm wondering what rate do they discharge at?

A good rule of thumb is basically use the mA rating (so 2800 would be roughly 2.8A), smaller packs can go a bit higher. But with that said, I have never seen any single cells go over 3A for any length of time without tripping the PCB.

Thanks for the info on the discharge rate. I was wondering about that when I was looking at wire connector options. I went for a minimum 5A just to be on the safe side.

But the 18500 1400mAh battery should be able to handle a (PC) with 2 crees in series @1A and flash in clash with a PEX resistored to give the 3rd Led the right voltage and 1A? Without tripping of course
