eGo-C USB Passthrough Issue

[Ephemerality]

Hi there,

I couldn't find any other threads with this specific issue, hopefully someone can shed some light on the situation.

I have a joyetech brand eGo-C USB Passthrough battery and I have been using 1.8ohm Kanger e-Smart cartos on it for a few months now.
All of a sudden, when the 1.8ohm carto is attached to the battery, it will fire for a second and then just shut off (light turns straight off) until it is plugged into a charger. I originally thought it might be shorting, so I cleaned out around the contacts and also tried lifting the pin up a bit in case that was causing it.
I eventually discovered that if I put a 2.2ohm or 2.5 onto it, it works fine for a while. It also works fine for a while if the USB cord stays plugged in.
However, after 10-15 minutes of using it with the 2.2ohm carto or with the 1.8ohm & USB, the button will flash three times and won't stay on.

Any thoughts on what could be going on? Does it sound like the whole thing is just toast or maybe just a circuitry issue?

I believe 3 blinks is for a short. If your battery is running 3.4volts, 1.8ohms is about the limit. I believe Joye has short protection for one time. After it is reset, you'll be doing damage to the circuitry.

It's good to have an OHM meter to check your toppers on occasions like this.

You're not tightening your toppers past "snug" , right? Check OHMS on toppers, then try on other battery.

They're definitely all still at 1.8, I checked them thinking it might have been a lower res coil for whatever reason.
It's strange because with the 1.8, the light shuts right off. With the 2.2s it works for 10 mins or so, then does the 3-blink shutdown.

They all work fine on another battery, so it's definitely just something wrong with this one.

I don't tighten past snug

the three blinks of light is the default for a shorted load(tank).
try slightly backing of the tank and see if it will go back to normal operation.
i have a generic ego style battery that does this exact same behavior.
gently lift up the center pin on your battery.dont over tighten your tank.
over tightening of your tank may have compressed the center pin of the
battery causing it to short against something in the battery.
i most often have this problem when the battery starts getting low.
i have also found with ego pass-through batteries that have funny electrical issues that
giving them a recharge with the standard screw in charger clears the problems up.

I've tried several different tanks/cartos so I know it's not just a bad one.
I lifted the pin up a bit previously and it did seem to help, but the 1.8ohm cartos just make the button go out immediately, the higher res ones worked for a bit.
I'll give it a try again. I also hadn't thought of trying the screw-on charger, I'll give that a shot too.

Worst-case scenario I might just have to bust it open and see if there's anything obvious wrong with the circuit.

Thanks!

I'll bet the battery is just ageing. I'm speaking of the true "battery" inside the thing you hold in your hand. The thing you hold in your hand that connects to the tank/carto is a "battery assembly". This battery assembly is comprised of a case, switch assembly, printed circuit - electronics - assembly, connecter, etc. Every time the battery is discharged and charged, it loses a little bit of its useful life. The smart electronics assembly inside is just doing its job - protecting the battery from too much drain by measuring the battery conditions under a load. If the amount of current drawn, compared to the voltage level is wrong, the electronics assembly shuts the thing down - to protect itself and you. This one appears to be just getting over (under) that hill. Retire this "battery assembly" or use it only on higher resistance tanks/cartos.

I am pretty sure I am correct. I have been an electronics tech since the 60's...and I just turned 69 in January. I am a lot like your battery on some days...

I was afraid of that, but I'm thinking you may be right!
Using the screw-on charger vs. the USB charger did get it working properly for a while longer, but it still conked out again.
Looks like it may end up being dissected for science.

Thanks for your help.

Don't just toss it. With a little work, It can become a good atty test tool. See my thread:

Half of this is a tool to reliably test your atty resistance. Holding a multimeter with both hands has a lot of variables and too often does not result in a reliable reading.
