Saying hi! And a little advice please?

[Jkeane]

Hi!! Been browsing the forum or a while lots of useful info on here . Been vaping for a few months and recently bought a t priv 220w, have it se up with a bonza RDA currently running at 0.19 ohms, running it with two Samsung 18650 2500mAh 3.7V batteries, the other batteries I use are the same but 3000 instead of 2500. Question is is this safe? I'm really struggling to get my head around all this battery safety and ohms law etc, although I am reading endless info about it. I understand I should be mostly fine considering it's a regulated mod? Probably just being paranoid but I'm new to all this and a natural worrier! Apologies for the long first post

It never hurts to be too careful! Battery safety is a must with Mech mods as well as a regulated mod. The batteries you are using should be fine, but always remember basic battery safety. Regulated mods have protections built in to the circutry, but nothing is ever full proof.

When using a regulated mod, a different formula than ohm's law is used. With a regulated mod, watts law is more applicable. Coil resistance becomes irrelevant. What is relevant is the wattage ceiling of the battery and the wattage setting you vape at. To keep it simple for you:

WATTAGE PER SINGLE BATTERY on REGULATED MOD:
(wattage doubles when using 2 batteries; triples when using 3 batteries)

My batteries aren't on any of them :/ and is the 3.7V a different measurement of amps? Sorry if I sound silly, also vaping at 75watts of that's relevant?

My batteries aren't on any of them :/ and is the 3.7V a different measurement of amps? Sorry if I sound silly, also vaping at 75watts of that's relevant?

Then you are most likely using a rewrap battery.

Are You Using a Rewrap (Rebranded or Aftermarket) Battery?

• Learn what a rewrap cell is. If you are using rebranded cells, does that mean it is inferior, poor quality, or even dangerous? Which batteries are suspected to be rebranded batteries?

3.7 volts is the nominal (average) voltage of the batteries we use. When fully charged, they are 4.2 volts, and will run on a regulated mod to around 3.2 volts or whatever the "voltage cutoff" is of the mod you're using. Your regulated mod will shut itself down at the voltage cutoff to avoid over-discharging your batteries.

If you are vaping at 75 watts, then follow the below recommendations depending upon how many batteries your mod uses:

-If you use a good quality 15 amp CDR battery like the Samsung 30Q or Sony VTC6, then you are good up to 45 watts per battery; 90 watts using two; 135 watts for three batteries.

-If you use a good quality 20 amp CDR battery like the LG HG2 or Samsung 25R then you are good for 60 watts per battery. If using a 2-battery regulated mod, you're good for 120 watts as you have two batteries. If you are using a 3-battery mod, you're good for 180.

-If you use a single 25 amp CDR battery like the Sony VTC5A, then you are good for 75 watts per battery, 150 watts for two batteries, and 225 watts with three.

-If you use a single 30 amp CDR battery like the LG HB6 you are good up to 90 watts; with a pair of 30 amp CDR batteries you could safely do 180 watts.
​

You don't sound silly at all. You are asking relevant questions to educate yourself. Batteries are the most important part of our vaping setups. You should prioritise your batteries to be the highest performing and safest batteries you can find.

3.75 is average voltage. Battery voltages actually drop as they drain. Think of your battery as a balloon filled with electricity. As the amount of electricity remaining drops, so does the pressure.

The t-priv is a two battery mod so even with 15 amp batteries you should be able to maintain 75w without trouble.

Thanks so much for all of that, shall definitely read through them I'm on with the video now. There's a lot to understand and I wasn't even aware of rewraps, these are just what the shop gave me with the starter kit and the 3000s are what they gave me when I bought spares

Rewraps are not necessarily a "bad battery". It is just that their advertised specifications are often extremely exaggerated. Battery Mooch has tested over 200 batteries; you can find his assesments and how your batteries rated here: Complete List of Battery Tests

Happy to see mine with a good review on that list Shall definitely get some which are not rewraps when payday rolls around though just to be extra safe

Welcome to the forum. A healthy respect for your batteries is good. Pay close attention to what @Baditude is posting, in-spite of his forum name he is a nice guy.

 

[Coyote628]

These are pretty much the same batteries i use in my tpriv. With the tfv12 king tank on top and certain coil configuration, i vape as high as 150watts ive had zero battery issues. The tpriv is a workhorse of a mod, if you get a good one. Mine sure has been and ive never even explored the temperature control mode functions. Ive used different tanks and rda's on it and it performs flawlessly. And the flashy LED lights arent that hard to look at either. Never found the lights to take away any extra power from my vape for that matter. You have a good setup, hope you enjoy. And welcome to ecf.

Very useful and easy-to-understand. Per recommendations on here, I use the Samsung 18650-25R. Never thought about the 30Q --hmmm.

Been vaping for a few months and recently bought a t priv 220w, have it se up with a bonza RDA currently running at 0.19 ohms, running it with two Samsung 18650 2500mAh 3.7V batteries, the other batteries I use are the same but 3000 instead of 2500.

If your batteries are Samsung, they're not rewraps (although it's always possible they could be counterfeit - there are an unfortunate number of risks when it comes to batteries). The actual battery manufacturers are Samsung, Sony/Murata, LG and Sanyo/Panasonic. A Samsung 18650 with 2500 mAh could be the 25R (especially if it's green). If the 3000 mAh batteries are also Samsung, they're likely 30Qs (which are pink). Do they have any other letters and numbers including the 25R or 30Q designation?

If you have 25Rs and 30Qs, you'd want to stay below 120 w with the 25Rs and below 90 w with the 30Qs. Since you don't know for sure it's a bit trickier. One thing to watch out for is whether the batteries get hot when you use them. Warming up is OK, but if you ever notice the batteries getting hot they're being over-stressed and they're not safe at that power level. Heat itself causes damage, so if batteries get really hot it's usually better to dispose of them (never in the trash - cover both ends with electrical tape and take them to a shop or recycling centre that deals with lithium batteries).

I'm afraid there are too many 'ifs' in this post to be really helpful. The sources everyone else has mentioned are very useful. If you have any questions left (or have thought of a few new ones) after reading up a bit, feel free to come back and ask. We're always glad to answer.
