Mech mod battery volts?

[Sabba]

So basically,
I have been vaping regulated mods for about a year and my friend has given me a geekvape tsunami mech mod and despite reading many posts on battery voltage I am still curious. I am using 0.3 ohm prebuilt tiger-coils and a Samsung INR18650-25r, I do not have anything to measure battery voltage and after hearing numerous stories of batteries venting and blowing up I am more than sceptical about using it. How long can I use the battery's for? If I do overdrain the batteries will I notice anything before anything bad happens?

Ty sorry for being a noob

As the battery voltage drops off so will the vape quality, you should be able to notice a decrease in heat, vapor output & ramp up time as the voltage decreases.

But, voltage drop isn't what may cause a dangerous situation when using a mech.
When using a mech amp demand is highest with a fully charged cell (4.2v).
You must have a way to at least check for shorts and accurately measure resistance to ensure you aren't drawing more amps from the cell than it can provide safely.

VOLT METER 510 CONNECTOR

The voltage tester screws into the 510 connector of your mech. Press the fire button to learn the voltage. Don't use the battery if the voltage falls below 3.4 volts.

Sabba, first off welcomme to ECF. The Tsunami is a decent mechanical device but it has both a hybrid cap and a regular 510 connection. I suggest that you use the 510 attachment to start with as it is somewhat safer for a mech beginner, secondly download an ohms law calculator to your phone or tablet, when you enter the resistance and the voltage, it will provide you with the amperage and wattage calculations for your build you are looking to run. 3rd thing is make sure that the wraps on your battery are not damaged, no nicks, cuts, or tears in the wrap that would allow it to ground out against the inside of the tube. The batteries you are running, the Samsung 25r's are tried and true mechanical device worthy cells, they are all I run in my mech's. If you have any questions regarding batteries check out our resident battery guru, Mooch, he tests many of the cells on the market and posts his findings. With the .3 ohm coils you are running the samsung 25r cells will handle it comfortably as it is only a 14 amp load and that cell can handle 20 amps constantly. I hope this may help you some but seriously check out Mooch's feed he has all the skinny when it comes to real time capabilities of vape cells. Good Luck and be safe

Specs on that battery show a low voltage cut off of 2.5v. However at .3 ohms the user will notice a significant drop in performance and vapor long before reaching the cut off voltage, probably as it drops below 3.5 or 3.6 volts.

eta: It was so much easier to take a battery down below cut off voltage when we were using higher resistance in the 2.5 to 3.0 ohm range.

Hi and welcome. First, I agree with the above posters: don't use the faux-hybrid (direct to battery) top cap; the 510 pin cap is much safer; and do by all means get an ohmmeter to check your coils before trying to fire them. Finding a short with the fire button is not a good thing. The 25R is a good cell, and can safely carry a 20A load, at least when new. As batteries age, their ampacity diminishes. FWIW, .3Ω is lower than I care to build on a one battery tube. I have been safely using mechs for years and I like to stay above .4Ω. Not only is it safer, but the battery life almost doubles. Low ohms eat batteries like a shark through a surfer, which is why you see competition vapers change batteries every few hits. I also think you'll be able to tell about the battery voltage. The vape gets weak below about half charge for me, even with my standard .5Ω coils. Welcome to the board, and stay safe out there.

heres an analogy... your car battery is nearly dead and you turn the key... ckick click click... wrrrrr wrrrrrrr click..

Welcome and glad you joined.

If your careful mech's are great 2 things to take into consideration does the 510 poke out enough to make a clean connection and what resistance can your batteries work down to on 25r's a, 0.25 build works well with very little heat build up on them. I've used 25 r's sony and lg's down to 0.18 0.15 0.20 and don't get hot just a little warm as the charge runs out so what i'd do is find a review for the mech mod have a look at mooch's reviews on batteries and download an ohms law calculator so every thing works as safely as possible

Thanks everyone for the advice
