Battery question

So I have this Samsung battery and I just recently got a TOBH v2 atty. I am wondering how low ohm I can go on my tobh with this battery in my nemesis. photo 2.jpg
 
Specs say its a 20 amp cell. I'll let you decide what your comfortable with. Steam-engine.org can help you with the calcs.

Is it 25 or 20 amp? it says 25R. Also I check my battery even vaping a kayfun at 1 ohm. I am paranoid about my battery. I dont want to push my battery at all and the lowest I may go would b .2 for competition but I am even afraid to do that with this battery cause I am not sure at all.
 
The 25 means 2500mAh. You answered your own question." I am even afraid to do that with this battery cause I am not sure at all." My opinion is if you want to go low sub ohm then get a battery proven to be able to handle it.....Sony VTC5 from a reliable source.

Ok Dirk thank you very much. I was just trying to see how low I could go on my current setup without having to worry too much about it.

Could be a lousy pic, but the battery in the pic looks grey. If you say its light blue, then it looks like a legit Samsung. It's a 20 amp continuous discharge rated battery.

Theoretically, you can use this battery down to 0.3 ohms. I like to have a margin of safety in my builds, so I wouldn't go lower than 0.4 myself.

1.0 ohm = 4.2 amp draw
0.9 ohm = 4.6 amp draw
0.8 ohm = 5.2 amp draw
0.7 ohms = 6 amp draw
0.6 ohms = 7 amp draw
0.5 ohms = 8.4 amp draw
0.4 ohms = 10.5 amp draw
0.3 ohms = 14.0 amp draw

0.2 ohms = 21.0 amp draw
0.1 ohms = 42.0 amp draw
0.0 ohms = dead short = battery goes into thermal runaway


Explain it for the dumb noob: Ohm's Law calculations

* I lied. I only build down to 0.6 ohms. :oops:

Great info as always, Now dont forget to check out the specs on that thing!! I am curious to get your opinion. LOL.

Wraith, honestly I don't know how to interpet battery graphs nor do I pretend that I can. I depend upon other people more knowledgeable than myself who can and who can explain in a summary about a battery's performance.

Got ya. Funny thing i see it shows the graph for performance of 2800 mah, but nowhere does the test data show amperage ratings?? hmmm.
