Pulse 80w

[Benjamin899]

evening all,

Got the new regulated pulse 80w from Vandy Vape.

In bypass mode is it completely safe? Understand it makes it work like a mech mod just wondering can things still go wrong If you don’t understand your ohms law or the fact it’s regulated stop all that?

Currently running .21 dual coils on the pulse 24 rda

Thanks

Anytime you are using a battery it can't be thought of a "completely safe".

• "Bypass mode allows you to apply direct voltage output from your batteries by bypassing the circuitry of the mod – much as you would with a mechanical mod (not recommended for beginners)."

What batteries are you using specifically?

Been vaping a good few years, so not a beginning just not to clued up on the whole mech side.

Using single 18650

Bypass mode doesn't make it into a mech. It just means you have to build to certain specs to get a good vape out of it similar to a mech. All protections built into the board (of which I don't know which ones the VV chip has) are still functional.

Then you are a beginner to mechanical mods?

A Beginner's Guide to Your First Mechanical Mod
Explain it to the Dumb Noob: Ohm's Law Calculations for a Mechanical Mod​

With a mech (or a regulated mod in bypass mode), you don't have electronic protection circuitry. No protection against short circuits, no protection against over-discharging your battery (stuck fire button), no protection against running down your batteries to a dangerous level (below 2.5 volts), etc.

You still didn't answer what batteries SPECIFICALLY you are using. Brand and model number. All 18650 batteries have different specifications (ie amp rating). Not all 18650 batteries are appropriate for a 0.21 ohm coil.

I was reading up and found out the whole point of bypass so thats why I was asking the questions.

Was willing to give it ago but wanted to make sure was safe before I attempted anything.

Thanks

Using an Ohm's Law calculator, using a 0.21 ohm coil will pull 20 amps from a battery. Your Samsung 25R is a 20 amp battery, so you would be using it at its maximum amp limit. I'd either use a higher ohm coil or use a 25 - 30 amp cdr battery to be safer.

Just note that a dual coil on a single 18650 isn't an optimal setup, you'll have a better experience using a 20700.
With your setup (0.21Ω, bypass) you're operating at or close to your batteries CDR which usually doesn't make for good battery life.

Are you absolutely certain about that, untar?

I merely copy/pasted how the bypass mode works in a number of different mods that offer it.

• "Bypass mode allows you to apply direct voltage output from your batteries by bypassing the circuitry of the mod – much as you would with a mechanical mod (not recommended for beginners)."

Maybe I'm misunderstanding.

I've never owned a regulated mod which had bypass mode, so I'm wondering why anyone would use it? Seems pointless to me.

 

[untar]

Afaik it bypasses the regulator part of the circuit.
Low voltage cutoff works in all mods I ever used bypass in, it shows "no atomizer" and "atomizer short" on the mods I tried so that would be most of the safety features. I didn't test any mod for over current protection so can't tell anything about that.
I already stated that I don't know about the VV chip, I'm talking about my general experience so far and what I would expect the board to do.

That would explain why my battery is draining faster then the speed of light

All of the bypass only mods I've used have low voltage warning and cutoff, reverse polarity detection, low resistance protection, a wattage or amp limit and x-second cutoff. The usual safety stuff. All of the VW/TC mods I've used with a bypass feature also have the same protections.

That doesn't mean the Pulse 80W has them. The manual should have the appropriate warnings.

Whether it does or doesn't, you should still build to the capabilities of the battery or to the wattage/amp limit. For example, the Pico Squeeze has a 50-Watt limit. No matter how (ridiculously) low you build, the circuit is limited to the amperage necessary to produce 50 Watts. For my builds on that device, I use a single twisted wire coil that measures 0.35-0.39 Ohms.

I have a Pulse 80W en route, and I plan to do the same thing with it. Though with the 80W's buck/boost and (hopefully) decent TC capability, I may live dangerously with a dual coil build with the same wire type and same resistance.

From reveiws I’ve watched apparently the temp control isn’t the greatest at the moment.

Hoping an update to the firmware will sort out that problem, what sort of wire do I need for TC? Used it back when I was On tanks and always found it to be good

 

[untar]

-stainless steel (can also be used in power mode)
-titanium
-ni200 (not ni80)
-NiFe (can also be used in power mode)
-zirconium

For some of these your mod won't have a preset and you'll have to look up the TCR and play around a bit with it around that value.

 

[Zaryk]

On all the mods I used with bypass, they still had the normal regulated mod protections. I actually use those to teach noobies that want to use a mech how they work and let them get the hang of how to run a mech and build for one while still having protections just in case there is a problem.

I cannot speak for the pulse 80w specifically, but I would be surprised if it bypassed the protections.

Okay so now I’m using my wasp, single coil which is running at 0.44

Safe to use in bypass?

That would be close to 10a, well within the safe range of the Samsung 25r.
I would highly suggest familiarizing yourself with ohms law, look up your battery specs on mooch's battery test results, and finding an ohms law calculator you are comfortable with. Even if you do not run a mech mod, it is a good idea to at least understand these things. Better safe than sorry.

Yea I’m going to have a read.

Time to read up the pros and cons.

Appericate all the responses

I'd say do the math yourself but sadly Zaryk completely ruined that

Is there a special reason you're fixated on bypass mode?

Wouldn’t say fixated, started with tanks,

Moved on to rda then got myself a sqounk mod and had bypass so just seeking some knowledge.
