Help!!!

[dragonlover]

Ok I woke up this morning all set to put my dual coil on my one still working Riva battery-and grr-that one is dead too! My 901 charger is also kaput. there is a place kinda close to my house that sells a 901 pass through-I have some kr808d cartos and a 901-808 adapter. Will that set up work until i can get a new riva battery?

Thanks

It sounds like it should work. So, can you draw the conclusion that dual coils killed your Rivas?

You might find a 7/11 or similar place that sells disposable e-cigs if it does not. You could use them when you leave the house also. Check the emergency needs thread at:Pay It Forward - PIF Someone might be able to help you.

not sure as the riva's were given to me and i'm not sure how old they are-the first one died before i got my dual coils so i don't think thats it. i actually was able to drive out to someones house and get some manual 510 batteries-charging them right now-still thinking about the pass through

never hurts to have a backup and do check the pif threads....someone my be able to help....

Dual-coil cartos will pull more amperage, sometimes more than standard battery setups can handle (at least in a sustained time frame). Put it bluntly, they will punish a battery that's not really designed for that type of load. I wouldn't use the 510 batteries with a dual coil, they won't handle it very well.

The adapter work up and work around may work, the passthrough.

k thanks- what battery should i get for my dual coils-they're 510 threaded

 

[ClayK]

I would say nothing smaller than a 650mah eGo type (they have 510 threads). If I recall correctly, 510 batteries are only like 130mah or so.

 

[wrigleyvillain]

240 mah I think. You want at least 450 for the dual coils (as well as for low resistance standard atomizers) so any eGo is generally fine. As long as you are ordering a new one may as well get a 900 or 1000.

This is from the Madvapes website. Not saying that this is why your Riva batteries died, but simply pointing this out as a "buyer beware."

"Please note that these are not sutiable for eGo, 510, 901 or mosfet driven type batteries. These are meant to be used with 3.7 volt mods with a switch capable of handling 2 or more amps. Simple testing shows that although these are low resistance, they work wonderfully on 5 and 6 volt devices. Your results may vary and the protection circuits on some batteries at higher voltages may see these as a short and not work."

I ordered some and there was a similar warning like WomanOfHeart posted with DO NOT USE with eGo and Riva. I am going to use them in a REO (18650 battery).

You could get a 5v manual straight passthrough at MadVapes, they'd probably be great on that.

 

[ClayK]

If memory serves, it's like 2.3-2.5 amps of pull (give or take), but I'd have to hook it up to the Darwin again to see. I would definitely recommend a 5v passthrough.

Going under 2 ohms on any mosfet type switching system is asking for trouble...they are simply not meant for the punishment...not to say it won't work but the abuse will drastically shorten the lifespan of your device.I'm surprised anyone gets very far w those cartos at all on a mosfet system...they would carry more current due to the second coil...sort of a double whammy there...good luck, hope you make it till your next order...
