Safety Question

[Noble Gas]

Hello, vapers!
As far as I can tell, everything seems to be safe, but I figured I'd ask just to be sure.
So here's the story:
Today I received my 1st mechanical mod (oh how I LOVE getting vapemail), and it's a lovely Sentinel M16 clone from 101vape.com. I got a Nimbus clone to try my hand at rebuilding, but it had problems and I'm waiting on its replacement. I also purchased an ohm/volt meter, plus a couple batteries and a Nitecore Intelligent Charger. All set up for dripping with my Kanthal and cotton (as well as spending about 3 weeks reading and watching info videos), but no rda. I really wanted to test out the M16 so I checked out the volts and decided to try my ProTank 2 on it. Here's how everything tested out on the meter, and my question is - does this look safe?

Sentinel M16 - 4.0 Volts
ProTank 2 - 2.5 Ohms
Sony 18650 1600mAh 30amp battery

According to Ohms Law I'm firing at 6.4 watts, which is well in the range of safety according to my power chart. Does anyone see any problems with this setup? I really hope not, because it's vaping like a champ and I love it. But please do let me know if there's an issue with the high amp battery or something I'm missing. Because I'm all about safety.

Thanks!

looking good so far... when you start building your own is when you need to double and triple check your work...you will eventually want to step up to the sony vct4 2100 MAH. just in case you get vape happy, you don't want to over discharge. good luck. D

Thanks, 2naphish! And yeah, I do get vapehappy on occasion, though I generally switch to another device before things get hot (assuming that's what you mean by 'over discharging').

Throw that power chart away. It's bunk. Your setup is WELL within safe range for what you have. That Sony battery is rated at 30amps, so your resistance can be as little as .2Ω on a freshly charged battery. I'm NOT saying that you should do that, but it's possible, and it's still in the "safe" range for your battery.
