Help!! coils and cherry bomber

[icharliex]

I recently purchased a cherry bomber box mod (I know it can be dangerous)
and i have a RDA that i can fit 3 coils on
also I have 2 VCT 5 batterys in the cherry bomber giving me 60 amps.
how many ohms do you recommend for a cherry bomber?.
as at the moment its really burning my throat and im using 90 VG/ 10 PG liquid (3mg)
Please help

Hi @icharliex . Welcome to the Underground!

First of all, Sony 18650VTC5 batteries are rated at 20 amp constant discharge rate (CDR). Any "max" or "pulse discharge" rate is best left as safety headroom. (For reference: http://www.orbtronic.com/sony-vtc5-18650-battery-imr-2600mah-genuine-us18650vtc5 ) Running two in parallel gives you a 40amp CDR. I would never recommend exceeding the CDR, especially on a mechanical device. I would highly suggest keeping your entire build above 0.1Ω total resistance. This will give you approximately 165W on freshly charged batteries. This is pretty much an extreme mechanical build and would probably not be a pleasant vape with only three coils. I would personally keep a triple-coil build to a total of 0.15Ω or higher for a pleasant vape. Of course, this depends on your atty/air flow and wicking.

Good luck, be safe and vape on!

aldenf thank you for the advice,
I'm not the best at making my own coils, so I have just ordered 3 tiger coils which will work out at 0.25Ω with all 3 installed then when I feel more confident I will move to lower resistance like 0.17Ω. Also for wicking rather than using cotton I'm gonna use ekowool as I have heard a lot of good things about it. Thanks again.
