Burnt Taste on one battery, no burnt taste on other battery

[BorealPants]

Quick noob question for all you veterans. I've only been vaping for a few weeks and over the course of the last couple of days I've noticed that my hits have a burnt taste on one of my batteries. I thought it might just be my coil / wick but I just swapped in a new 1.5 ohm coil in an EVOD 2 glass. I thought I'd solved the issue but upon switching to my other battery I get a funny burnt taste. I have 2 identical Ego C-Twist batteries, both are dialed in around 3.7 volts yet I only get the burnt taste on one of them. I've tried my best to get any juice off the contacts but i didn't think that would cause the issue since i can't imagine the battery contact gets very hot. Correct me if I'm wrong, any ideas?

Thanks!

I think the most logical reason must be that one is clearly a higher voltage than the other, resulting in a higher wattage. you are getting dry hits off the one

you could easily turn that one down to fix the issue

X2, one is running at a higher voltage. I agree to dial that particular ego down to compensate It must not be volting true. That's one possibility.

eGo Twist has been proven to downshift voltage when it approaches the amp limit. The two you have may handle the stress differently. You can prove this with an inline 510 thread voltmeter. Recommended. Moving to the 2 ohm to 2.5 ohm range may put you into the sweet spot for current draw on the Twist.

You are pushing the 2.5 amp limit at 3.7v (2.47 amps) with the 1.5 ohm coil. Past 3.7v it will throttle back the voltage to prevent cutoff. The Sigelei Zmax has a 4 amp limit if you like the 1.5 ohm coils.

I've been experimenting w/ the 2 ohm coils. I'll keep playing around w/ the voltages and resistance. I dialed down the battery giving me the burnt taste and it seems to have done the trick. I might have to upgrade to a mod w/ a more reliable voltage control and longer battery life...

Doing this will open a whole new world of being able to control vape and flavor profiles for your ejuice.

Watch this review by Phil Busardo. He conducts testing on resistive loads at various voltages and produces a chart about mid point of the video where he explains what happens with 1.5, 2.2, and 2.7 ohm coils. Looks like with a 1.5 ohm coil it can only produce a 3.7v output when it's asked to go above that level due to high amp throttling of the PWM circuitry. You'd be happier with a 2.0 ohm coil and higher in the Twist if you want full range control and voltage accuracy.

Yeah... VV is kinda like having a Volume Knob on your Stereo. Verses just an On Off switch.

You might also just use a multimeter to check output voltage.

 

[DaveP]

It's pretty much fact that less than 2 ohms stresses the overload detector and it scales back to just under the max current output.

That's my answer and I'm sticking to it!

I burnt my ego battery trying to fire my patriot RDA lol Was curious to see how low of a resistance the battery would last. Apparently, it didn't even make the first hit, the only vapor was the smoke coming out of the battery haha!

I'm sorry, but that's NOT funny!

If you're operating a mech mod you should know the amp limitations of ANY battery you are attaching your RDA to BEFORE you fire it. Anything else is just plain reckless
