Possible? Sure - the biggest thing would be to ensure the constant C rating of the batteries - each would have to safely provide a constant over 2 amps each in a parallel setup. Assuming a 3000mah battery is capable of 1C, this would work, but the mod would only last about 1.2hours total. Assuming a series setup (more likely - but could be using a boosting controller for the parallel setup) - each would have to provide a bit over 4 amps each, so the battery would have to be at 1.5C constant safe discharge, which would put the discharge at 4.5 amps each. This setup would last approximately 45 minutes.
The times above are total time - as in duration of button presses aggregated. Also this is assuming perfect efficiency (not a reality) and perfect capacity.
:)
Would it be posible to build a mod running on 2 18650 batteries, with build in Volt indicator, that could run a triple coil carto at 1.5 Ohms set on 6 Volts? That would need 4 amps to be handled! :closedeyes:

OK, good to know. So a little critical this setup I believe.


It is said now by the people who are having triple coil cartos, that they get to hot at 6 Volt, They seem to be best around 5 volt, what would make the setup less critical I supose. It would need a VV set at around 5 Volts

Will have to think a little more about this.

Thank You for your quick answer B94Cast.

I have seen people reviewing the trustfires 18650 "flames" batteries, rated at 2400 Mah, to be real 2400 Mah, and having 2C discharge rating, so these batteries should be fine I suppose.

Oh nice - hadnt got to digging around to see if anyone had done any proper testing on these yet.
