I don't think that battery have enough amps to fire this, you'll need a new battery.
Not sure that's what's causing the drop, but regardless you will need a different battery, I just looked that one up. That's a protected battery with a 6.4 amp continuous rating (C rating and mah).
Edit: your picture isn't loading now for some reason, what resistance are you firing? I don't think the IPV2 can down regulate voltage, which i believe means the lowest it can fire is the voltage of your battery(someone correct me if I'm wrong). It will show 3.2 on the screen, but its not supposed to be able to actually put out 3.2 volts

Allright which will be the best battery for this a vct5 or an efest 35ma or Any other suggestions?
Or Just start building 1 ohm and up in stead of 0.4 i guess will do the trick, hmm how many wraps and what diametre would be best....

VTC 5 is what I use, the 35 amp efest isn't actually rated to 35 amps if I remember right, and the VTC 5 is 100 mah more anyways. Did you see my edit to my last post? What resistance are you firing?
Edit: Ya that's definitely why, .4 is at the low end of this device and your battery cannot handle that with only 6 amps. Using higher resistance is definitely best with these.
There are a ton of building tools that will tell you with wraps and diameter, I can't remember any of them, you start being able to eyeball it after a bit, but a Google search should turn up a few.
Make sure whatever coil you build will be under 6 amps at 4.2 volts until you get a new battery, just to be safe. Stay above .8 until you can get a VTC5

Thought the Panasonic 3400mah 18650b was one of the better batteries but not for subohm i understand now [emoji1]Get a. Sony lol stop buying cheap batteries
Just remember always check your load rating on the batty no worries idk my personal perfrence is nothing but sony I even have them in my lil 15 watt boxs lol
I just edited my last post, not sure if you read it, but want to emphasize, stay above .8 at a minimum until you get a couple VTC5s, you're battery can't handle anything lower and .8 is almost maxing your battery
Didn't know it was 3400, thought it was 3200, so you have 6.8 amps not 6.4. Not much of a difference but thought I would put the correct info out

Panasonic batteries are superb , you just bought one that doesn't fit well with your device , i actually prefer Pani's over Sony's but not with these devices.
I have VTC 5's 2600 mAh in my 35 watt and they are OK , nothing great in my opinion.
The IPV2 does not do down regulation on battery voltage. What this means is that your minimum wattage is limited by the voltage coming from the battery regardless of your settings. So even though you have set it at 7 watts, it is actually going much much higher than that based on the resistance you have on your coils and the voltage from the battery. At 0.4 ohms, it is actually pulling around 34 watts and 9.25 amps from the battery. You're very lucky you have a protected battery because you could easily have caused a catastrophic failure and a venting situation.
Exactly. And to be safe, assume your battery is always charged to 4.2 and determine amps and wattage from that.
Good info guys , i chose the Sony batteries because of the higher amps limit .
To be clear, my advice to use 4.2 to determine amps only applies if your IPV2 is showing that it is putting out below 4.2 volts.
Don't want to confuse someone and have them use 4.2 volts to determine their amperage when their IPV2 is putting out higher voltage
No problem frank, always good to ask questions to be on the safe side.

I was commenting on checking what your devices amp limits are and choosing the appropriate battery beforehand.
Ya that wasn't directed towards you, it was towards random people who might happen upon this thread. I am bad at making clear who im talking too, I just quoted you because you said good advice
Me too lol, my comment was directed at anybody who cares to read it .
