LiPo mods charge faster/last longer than 18650 mods?

[alicewonderland]

Anyone have experience with both? I have a solara dna 30 and recently bought a rdna40. The fully charged 18650 in a VS seems to last only 1-2 hours of heavy vaping for me and takes almost a full night to recharge the battery. The Solara DNA30 I been vaping on I can heavily vape for 4 hours+ without going on a recharge, and takes less than an hour to recharge. I can vape on it from dead battery life while its charging and it still charges to full quickly. Is this a common thing with LiPo vs 18650's ? oh and im vaping 0.5-1ohm coils at 30 watts on both all the time mostly, i usually just swap over the RDA to the solara when the vaporshark is out so the coil and RDA is the same .

i just chcked the dead battery on my rdna afte ri hooke dit up to my usb port an hour ago... its been reading 0 battery life this entire time but when i took it off it still read 0, when i conect an rda to it and try to fire it up it read 100%... what is up with these dna40 boards?

and can explode!

Folks keep leaving that part out. A LIPO cell is not safe chemistry!

Type "worlds most dangerous battery" into your search engine and see what comes up.

18650 batteries, even in safe chemistry, also explode.

LiPo batteries due to their construction have higher electrode surface area and more "battery stuff". This allows for higher capacity and higher C rates.

That said, to the best of my knowledge, all modern lithium chemistry batteries can charge at 1C, which means they would be fully charged in an hour by a proper charger and power source. I'm not sure what is going on with the VS, maybe you should pick up a dedicated charger for your 18650s.

Yes, any battery can be made to vent ... there are no exceptions. So the question becomes 'what happens should the battery vent'?
Lithium Cobalt & Lithium Polymer both vent in a violent manor. Lithium Manganese does not.

So I would ask, why use ICR or Lipo cells when there are so many safer alternatives?

LiPos have a lower voltage drop and a flatter discharge curve, making them deliver useful current even at lower voltages.

That being said... I'm not sticking a lipo in my mouth. I prefer those flying around at a safe distance, mounted in a RC heli. LiPos are about as unsafe and unstable as consumer batteries can get. Baby them and treat them like eggs. And read up on proper lipo safety.
