18650 battery Amp rating question

[kwazydude]

After looking at Steamengine's safe sub-ohm battery chart, my question is: I will soon be getting a Godbox, which uses three 18650's. Are the amp rating chart safety specs still applicable as if I were using just one 18650, or do I need to take into consideration that there are 3 of them? In other words, is the collective rating on three 30 amp batteries now 90 amps? If so, how can I calculate the safe ohm coil build?

Also, someone warned me that 18650's are not safe to use in mechanical mods. Steamengine indicates that IMR hybrids are OK there, but doesn't mention plain IMR's. Any comments?

The box is parallel? Parallel increases amperage and mAh. So if your batteries are rated at 30 amps, then yes you have a 90 amp limit. It is essentially taking the load to fire the atomizer and splitting it into 3 batteries producing their own 30 amps each. For series, it is using the batteries to combine voltage. Hence 8.4v

Yes in parallel the amperage is split between the batteries but for safety I would assume worst case and not exceed the specs for one battery. If you have a bad connection or a battery crap out the good battery can safely handle the load.

I just received my God 180 a couple days ago. The three batteries are in series. The amp rating would remain the same, while the voltage is effectively tripled.

So I assume any decent quality high drain 18650 rated 30A or better would be a good choice?

Though theoretically the amp limit will increase to 90A with 3 30A cells in parallel, realistically this is not the case.

The mod has the batteries in series. The total current runs through each battery .

All three batteries need to match, buy them together and keep them together. Check the voltage of each cell before and after charging and if there is a difference do not use them in the mod any more, you can use them in other mods with single or parallel batteries. I would not charge them in the mod, take them out and use a good charger.
