Vamo V5 watt and volt calculation

[cerebralscope]

Bear with me if this is long winded

The Vamo V5 has the following specs

• Variable Wattage - can be adjustable from 3.0W to 15.0W
• Variable Voltage - can be adjustable from 3.0V to 6.0V

I was doing some calculations to see the tolerance of batteries and something doesn't make sense

Assume I have a resistance of 1.8 ohms

At 15W and 1.8 ohms => 2.88 amps
At 6V and 1.8 ohms => 3.33 amps

Both the numbers above show that it is safe for my Panasonic NCR18650A (couldn't source for a high drain at the moment)

====

BUT, if i run 6V and 1.8 ohms also calculate to 20 watts which is above the Vamo's 15 watt stated ceiling..

SO the question: If continue to run the vamo at 6V persistently, will it spoil it?

Or did i mess up the calculations?

Try this
Battery mAh & C Rating = amp Calculator

At 1.8 ohm the chip may not allow it go to 6v even if set for that

Thanks much old bike guy save me some punching into the calculator... the numbers seem good

So any Vamo v5 users my question was can I run it at 6V persistently knowing that its spec only states 15W ceiling not 20W?

If you had a way to check volts going to your topper I'll bet the chipset would cutoff at the voltage needed for 15watts at 1.8 ohm even if set for 6v, or they would be trying to sell it as a 20watt mod.

All of your calculations are correct. Even though you set your voltage to 6v the Vamo will not deliver 6v if you are using a 1.8ohm coil. It will only deliver 5.2v because of the 15 watt ceiling.

No, you will not hurt your Vamo to run at a higher voltage because the vamo will automatically adjust the voltage (if needed) to keep the power below 15 watts.

Ah thanks, good to know it should be fine. I wanna take care of my stuff cos getting them is not so easy where I come from.

So where is Sinkie Town?

When you are dealing with electronic APV's it isn't just about running the numbers on the batteries and/or the stated max volts/watts of the APV. An electronic APV has built in shut down cutoffs to prevent unintentional damage being done to electronics and even the wiring of the APV. A VAMO is going to roll back the voltage or wattage setting if your combination of device resistance and volts/watts is beyond the preset limits built into the VAMO. Constantly pushing it at the extremes isn't a great idea, but then again I don't think you could ever get a tolerable vape experience trying to run any 1.8 ohm device at 6 volts either.

its in the Far East, little island with crazy laws made by a political party that has like 90% of the seats in parliament.

the 1.8ohms are off the clearos i will be getting, its just extreme use-case testing... sorry I work in info technology and try to break systems with "edge case" scenarios is kinda second nature to me

 

[Bunnykiller]

you can set it for 6 V @ 1.8 ohms but the chip will limit it to 15 W

kinda like setting the cruise control for 100mph on the car but the engines rpm limiter will only let the engine get the car to 80mph

what's a good tank with vamo v5 ?

Here is mine with an Aerotank Mega clone with the 18350 battery:

I also have a stainless steel Tobh v2 clone on the way. Do you plan to rebuild your coils?

 

[Dampmaskin]

Sounds like a job for my latest calculator.

Wow... i was thinking the mega was a little big but it looks good in the vamo

Sounds like a job for my latest calculator.

Sweet tool u got there...

I chanced upon Pbusardo's review of the vamo v5 at about 21:00 onwards, quite informative if you wanna check out how the chip performs
