A question about the Alien and different tanks

[dyanaprajna]

I have the 220 watt alien with the Baby Beast. I currently have the Baby T8 coil in the tank, it's a .15 ohm coil, reading on the screen at about .17 ohm. I put my Cloud Beast on it, with the T8 .15 ohm coil, reading about .18 ohm. But when i hit them both at 75 watts, the Cloud Beast reads a higher amp output. Why is this? I thought the Cloud Beast was compatible with the Alien. With the Baby Beast at 75 watts, the amps read just over 20, but with the Cloud Beast at 75 watts, it reads just over 21 amps. If it matters, I'm using Samsung 25r batteries. Any help would be much appreciated.

Sounds absolutely fine. Your Alien is working fine and that 1A difference isn't an issue. And your batteries (assuming they're authentic) are beyond adequate for your current draw at 75W.

Were these on the same batteries? was this done consecutively on the same batteries? As you use batteries the voltage drops so to achieve the same watts more amps is drawn... just a thought

Yeah. I took a hit with the Baby Beast, then put the Cloud Beast on and took another hit. Consecutive, same batteries.

I am using the octocoil (T8) in my Cloud Beast right now at 110w on my Alien. The BBB with Baby octocoil is on my G-Priv @ 60W.

Similar resistance (0.15-ish) but the CB requires much more wattage IME.

Why is this? Can't help you there.

I have another, related, question.

I put my cloud beast on the Alien. I took a hit, and the screen reads 4.1 volts, 22 amps, at 85 watts. If understand correctly, I would take the watts, 85, divide by the volts, 4.1, and get 20.7, which is how many amps it's using, even though the screen reads 22 amps, correct? I'm just trying to make sure I'm staying in the safe zone, better safe than sorry.

EDIT: since it's dual batts in series, it would be 8.2 volts, for an amperage of 10.3, correct?

what you see on the output of the screen isn't the voltage of the batts, it's the volts the chip is putting out. you would divide it by the actual battery voltage which depends on the charge.

realistically you can just take your watts and divide by 7.4 (nominal voltage of 3.7 times 2 for series) to find your safe limit. with 20 amp batts you are good for 150 watts. some will say less because efficiency and the charge can drop lower, but realistically we have head room in batts already and once you start dropping below 3.7 your mod isn't going to output 150 watts anyway

Thanks. That's pretty much what I was thinking, but I was still a little unsure. I appreciate the info.
