I have a mech mod and have always used it with no problem. Now i'm scared to use it because i hear that it can explode on you if the proper battery is not used, I was using an 18650 icr protected and was told that was dangerous and to only use an unprotected high drain IMR or a hybrid, si i got the Panasonic ncr18650 2900mah hybrid for my svd but i would think i should use a protected in a mech mod. any help please?

Use a 2 cents for safety fuse if your concerned. If you stay well within the batteries amp limit you will be ok.
I personally don't push my batteries more than 50% of the amp limit but I would think 80% would be a safe limit.

You are correct in that using a protected li-ion battery is dangerous. In a mech mod, it is best to use either an IMR or hybrid IMR. Be sure to understand ohms law as well. You never want to push more current (amps) than the continuous amp limit on your battery. I believe that battery, the Panasonic NCR18650 2900mah, has a 10 amp limit.
Ohm's Law Calculator
Use this calculator to help. Use 4.2 volts as a starting point (as that is the nominal full charge of the battery) and put in the resistance (ohms) and press calculate. As long as the current stays under 10 amps, you will be fine as mechanical mods never perform the full 4.2 volts at a full charge due to voltage drop. Doing this keeps you in the safe zone.

It all depends on what ohm your wrapped at. If you're sub ohming then I wouldn't use an ICR. I use EH's 2100 mAh with a 60amp burst output and 30 amp continuous output. I'd much rather pay for the batteries than end up with a venting battery. Dangerous.

An IMR or IMR/hybrid battery will have safer chemistry than an ICR battery. Safe chemistry batteries will not vent flames or explode. ICR batteries may vent flames and explode and are obsolete for mod use -- not recommended.

yeah, loose the battery, you want an IMR high drain 30 amp continuous 18650 battery. The Sony VTC4 or 5 will do nicely. IMR are just a safer battery chemistry.
The reason the ICR's are protected, is that their chemistry is not the most stable, so it has a protection circuit the blows when it starts to be demanded of more than it can do before she blows. The unprotected are such that they don't require a protection because they are of a much safer chemisty, and won't blow up, they can vent if over taxed and misused, but no boom.

can someone help me? if i calculate 4.2 voltage (e) times resistance (r) 1.5 i hit calculate and the current(I) READ 2.8 and power read 11.76. now the battery is a Panasonic hybrid unprotected ncr 18650 2900mah 10amp. so is that a safe reading and if so why? does it mean i can set my power at 11.7 and voltage at 3.0 because i double the ohms to set the voltage. I'm really trying to understand this and i feel like I'm close so any help would be appreciated.
I think you read something somewhere and confused yourself.
What? 2.8 amps? Yes; 2.8 amps on a battery rated for 10 amps is safe.
(I) is your current in amps. At 2.8 amps you are well within the limit of your battery which is 10 amps.
The power means wattage output, voltage is the input, current is the speed or flow of electricity, and resistance is the impedance or interruption of flow.
Hope that helps!
Welllll, the choke point is the 10 amps. That's just not much, no, not many amps at all. Not a lot of usable power, and can not be pushed very hard either. 30 amp continuous, 30 amp continuous, 35 amp and 50 amp continuous would be even better, but not 10 amp, just not enough usable power. You'll stop using them before they die, because once you use 30 amp batts, the 10 amp batts won't be used no more, cause they are pitiful. Waste of resources. lmao
what is the power reading on the ohm calculator? i know voltage times resistance will give the current but whats the power that read 11.76
