How long should a Sony VTC5 last?

[Russyrex]

My setup is a mechanical mod (sentinel m16), Kraken dual micro coil @ .3 ohms and on a full charge I'm getting maybe 100\150 puffs (3-5 second puffs). My Sony v3's (1600mah) last way longer on a dual coil @ .5 ohms (haven't actually had one die fully, as i charge them every night). The VTC5's last maybe half the day and die completely...any ideas why these are dying so quickly?

A drop of .2 ohms results in a 40% increase in amps drawn.


On a freshly charged 4.2 volt battery...

4.2 X 4.2 / .3 = 58.8 watts / 4.2V = 14 amps
4.2 X 4.2 / .5 = 35.28 watts / 4.2V = 8.4 amps

Your batteries are dying so quickly because you increased the power drain by 40% when you lowered your coil resistance.
