Sanyo 16650 3.7v 2100mah battery in Ismoka Igo

[Shrub_rocketeer]

Hi all!

So before i ordered my mech mod (which i'm still waiting for from FT) i borrowed a friends to see if i get on with it. This got me into rebuilding my protank heads with micro coils. I found 1.3 / 1.5ohms to me be my personal sweet spot, and would love to use these on my current battery set up. I'm currently using the totally wicked Tornado RCS (or ismoka igo as its also called when unbranded) It uses a Sanyo 16650 3.7v 2100mah L-ion battery which seems to be protected from what i've read on flashlight forums. This can be used in regulated or unregulated and has short protection etc.

My question is, is it safe to use a build that low on it? Seems it would draw 2.5A and 9.1W. I dont want to try it and have a serious battery issue. I cant seem to find much information on this product at all.

Hope someone out there has the answer!

Cheers

The batteries should be ok I believe, but your math is slight off. Most batteries in a mech put out 4.2v fully charged and not 3.7. This means at 4.2v, 1.5 coil, you get 2.8amps and almost 12 watts. Here is a popular ohms law site you need 2 of the 4 and hit calculate.

I wouldn't do any sub ohming with those batteries.

The Sanyo UR16650ZT battery is not protected and specified at 2C, which means that it's safe up to 4.2A. The new version with 2500mAh is safe up to 5A.

It works fine with micro coils, but it doesn't work that great with the ProTank (or the included BCC tank if you have the full kit) because the airflow from the bottom isn't that great. But it does work fine with the Aerotank and 1.5ohm dual coil heads (and still has a two-day battery life) or the ProTank with a micro coil and the airflow controller base where the airflow is from the sides.
