32650 Unprotected/Protected Li-Ion

[Onryo]

I have been using AW IMR red unprotected cells for most of my builds. I am always worried about them being discharged below their braking point. A real pain to check the voltage all the time. Recently I needed a D (32650) Li-ion. Picked up a Feilong over at feilong (the postage was stupid expensive to Europe). Still unprotected.

A friend of mine told me the same battery is sold for 17USD with free shipping over at 32650 Unprotected. I got this battery too and indeed it “acts” like the Fei-Long. Probably i the same battery.

Then I saw there was a protected version of this 32650 battery for 22USD! 32650 Protected

What I am wondering is will a protected battery be able to fork out the current needed for a boost driver that feeds a M140 diode with 1.82A? I am a little iffy it it could. 3C I guess means x3 of the total capacity?

Can somebody shed some light on this?

3C means you can draw 3x the total capacity of the battery. You can easily run a 1.82A boost driver from those.

Thx, just what I wanted to hear =)
So this protected 32650 can pump out 15A 3x (5000mA) of current but the protecting circuitry limits it to 5A or so. Just like you said more then enough =)

BTW I tested out the unprotected 32650 (6000mA) by changing it with a CV/CC charger to exactly 4.2V. Put a load 1 ohm (10 Watt power resistor) across it and measured the voltage drop every 5 min. Stopped at 3V =). Both the Fei Long and the Kaidomain discharged exactly the same.
