Considering a Reo Mini 2.1: Battery / Resistance / Amperage Considerations

[bfisher]

Hey Everyone,

I'm considering purchasing a Reo Mini 2.1 and therefore doing a little research.

I've noted that Rob recommends an AW IMR 14500 battery for use with the Reo Mini 2.1. The specifications for this particular battery suggest that it can support a maximum voltage of 4.2 V and can support a maximum discharge current of 4 A.

I'm primarily worried about the maximum discharge current specification. If my calculations are correct, then I should not attempt to use a resistance below 1.05 ohm. This, I think, will be alright. I'm not (as of yet) particularly interested in sub-ohm vaping. I just want to be sure that I'm operating the device safely and within specifications.

I'm thinking about using a 1.5 ohm coil in order to obtain about 9 W of power at the Nominal Voltage 3.7 V.

Does this sound alright? Am I missing anything?

The Mini 2.1 uses a 18490 battery. The Mini, which is no longer in production, took the 14500. I use a coil as low as .85 on mine. Usually I run around 1.1. With the upgraded contacts in all REO's you will not have any problem going sub-ohm if you choose. I will let someone that knows lots about batteries handle your question of safe range.

Ah, thanks for the quick reply. I was just glancing through the user manuals for the Reos and noticed the specifications for the mini. I didn't realize that the battery had changed for the 2.1. For some reason I'm never able to reach the REO Mini information section on the website.

The AW IMR 18490 has a 16.5A limit. That means you could theoretically go as low as 0.3 ohms, though for safety you should keep it at or above 0.5. By comparison, the EFest 18490s are 8.8A batteries and should stay at 0.7 ohms or above.
