Which component is the limiting factor in ego battery power delivery?

[Skree]

not entirely sure this is in the right subforum but seems like the best place to me. I've got a couple of ego 650mah batteries left over from my first vape purchase. They came with CE style clearos at 2 ohms. I've moved on considerably from then but have an unregulated 18350 mod that i want to make regulated and use with a small rebuildable at a similar ohms

Planning to try and coil said small dripping atty for the egos once it gets here so i can use them till they die, but i'm wondering what component it is that fails as it can't take the load? is it the battery itself or the circuitry that's in the tube?

The idea i had was to rip apart the egos once they fail and take out the circuitry, desolder the switch, and fit the circuitry to the mod i have.. obviously i don't want to chop up my 18350 mod if it's the circuitry that fails

I believe it is just the battery that reaches the end of its usefulness & can no longer hold a good charge.

In some instances of a short circuit I've heard of MOSFETs dying and the like, so using them with RBA can be a touchy act. I like to make sure they work on something else & they are of an Standard Resistance range before ever putting them near my eGo batteries.

If they are eGo-T batteries, they may not run an RBA at all. I've tried a few different setups on my eGo-T battery and it always flashes to indicate a short. Transfer these to my eGo-C Twists and they work fine. Some limitation built into the device that I don't understand.

Too low resistance and hitting a built in current limiter perhaps? i've had mine operate fine at 3.5, 2.4, 2.1, and 2.0 ohms.. they do get bloody hot when chainvaping at 2 ohms though. they are ego-t batteries. could it be a slight difference in ego-t connectors?

now that i think about it, i test fired my aga-t2 on them too and they gave enough power to pop one of my crazy fail coils at the positive leg hot spot.. that was a 2.7 ohm ish coil when it wasn't shorting on the wick.

Thanks for the info, i thought it would be the cell itself failing.. good news for me if i can get sufficient performance out of my upcoming dripper at ego voltage cheers!

Hmm that is indeed odd. They aren't too low resistance, as I aim for 2.4+ if I'm going to use it on an eGo (mostly my A7). But I've tried my AGA-Ts, rebuilt VVN & A7 without any success, it just locks out then blinks when I remove the atomizer. Just put my carto-tank on w/ Boge SR and it fires fine haha.

But yeah, I don't see why the internal circuitry wouldn't continue to operate fine after the cell goes.

If my eGo-T weren't acting up I may give it a try. It is the USB battery though so maybe that plays a role in it refusing to fire.
