Sigelei 30w battery load

[i_L1fe]

Got the Sigelei 30w yesterday and enjoying it. Am however running into a particular issue at 30W.

Prior to purchase played with ohm calc and determined the existing EH 18650 2000Mah 16A batteries I already owned would work fine in this device. (Prefer larger coil/ohm @ higher volts than smaller coil/ohm @ less volts.)

Have 3 of these batteries...depending on battery I get 5-15 pulls at 30W before check battery error. Sigelei feature showing voltage under load drops 2 freshly charged 4.2V down to 2.8V. The other drops to 3.3V under load.

So...are all three of my batteries beat up and performing poorly? Or is this expected? Wouldn't think that the battery still showing over 4.18v charge would refuse voltage load up to 5.19V.

Present setup on it a new Zenith v2 @ .9ohm, 30 watts is ~5.7735A , ~5.19615V.

How low can the battery voltage get on a SX300 and/or DNA 30 before it wont fire at a set wattage. Like my example of needing 5.19V...can the chip boost up to that voltage when battery is say down at 3.5-3.7V?

Thanks!

P.S. Went to batteries plus searching for a 30A. They wanted to sell me a P25 Nitecore Flashlight Battery 18650. Told em wouldn't work as too low amps. I was instructed that all 18650s are 2amp and what is important is Mah...many of their customers use that battery and it should fire at 30W no problem. HAHA. Pointed them the direction of C-ratings on batteries.

Hmm...Ok.

Will be visiting local vape shop later today and see if they will let me run some tests on their 30A IMR batteries. Will update with my findings.

I'm not sure about the SX300, but on the DNA30, if voltage under load drops below 3.2 volts (I think it's 3.2) it will give you a check battery error.

Honestly, I would say get yourself a few Sony VTC5's.

Yup. Looks like all three of my IMRs were toast. Or EH just performing really poorly in general...usually vaped on my vamo @ 9-13W.

Picked up a VTC5. Voltage drop now reading 3.7 on fully charged battery when set @ 30W. Also, FYI...the new one it wasn't charged when I got it. SX300 refused to fire @ 30W when battery was reading 3.5-3.6V. Once fully charged it's working well. See how low charge can get before it won't fire...

Playing with higher ohm dripper builds on this guy.

2x 20 wrap microcoil on 3/32 bit. Comes in at 1.6ohm. @ 30 watt providing 6.92V and vaping like a champ. Lots of wick/wire contact. Hmm tasty.

The Sony VTC5 all the sudden started to not fit correctly. It appears either the device and/or my Efest LUC v4 charger managed to push in the positive contact on the battery. Tried adding magnet...device didn't like that...So pulled up on the battery positive to try and make a mini nip. Worked well. Now battery drop off at 30w reading 3.9 on fully charged VTC5.
