My new Sigelei 30W finally came in from Fasttech today. Running on an Aqua clone dual coils 28AWG @ 0.8Ω / 19.5W. Pretty happy with it so far.

I probably should have paid attention to the flat-top batteries sometimes having issues, because the batteries I ordered are flat-tops. Oops. -_-

I think they made some changes to the newer ones that make flat tops work better. But I don know that for sure since I have all button top batteries.

Just thought I'd pull this forward for those interested :)

Hey everyone, if you're interested in picking one up for good price, and you're a verified member, go check out the Co-Op section ;)

Mod: I can't remember if this is allowed, if not, please remove with sincerest apologies :)
 
OK here's a dumb question:

According to the official specs, the SX300 chip does not do down regulation and it can fire at 30W down to a resistance 0.5 ohms. Pretty straightforward, right? However at 0.5 ohms on a fresh battery at 4.2 volts, that gives you 32 watts, which is over the chip's 30W limit. In order to get 30 watts with a 0.5 ohm resistance, it would need to be firing at 3.87 volts, which is 0.303 volts below the actual battery output voltage. So in this case, does the mod actually fire at 3.87 volts or 4.2 volts? Is it going to go over the 30 watt limit or reduce the battery voltage?

stanthemanchan, that's a very good question. I'll do my best to answer it once I'm able to speak with Ms. Ivy.

But in the meantime, if anyone else with more SX300 chip experience has the answer readily available, we would be most grateful for your input :)

The battery level under load is lower than 4.2V. You will get around 3.9V, but no more than 4.0V on a fresh battery under load with a Sigelei 30w.

I'm having an issue on mine where the steel ring right below the fire/power button starts to get really hot to the point of almost burning my finger after 7-10 seconds at 17 watts. This only happened today and I've been using the mod since Saturday the 2nd. At 20 Watts, the power button itself starts to zap my finger a little bit.

I think this is a different manifestation of the flat-top battery issue, because I opened the mod up and now the positive contact appears to be tilting to it's side just a little bit... not sure if that's how it came or if it's been doing that because of pressure from the battery. This is just fantastic -_- now to spend more money on button-top batteries, yaaay.

Additionally, I'm not sure if this is just a usual characteristic of the mod itself, but the battery's voltage appears to drop drastically (from 4.2 volts to 3.5) upon firing. (I'm not talking about the voltage the mod boosts it to on the left side of the battery meter, I'm talking about the number right beneath it).

*edit*

Disassembled the entire unit (unscrewed the botton knob AND the tube itself, then fit both back on). Now that issue went away.

What the heck is with this thing? <_<

I'm just starting to try to figure this mod out. My problem seems the opposite of what others are having. With sony vtc4 button top it will only close if I leave a big gap of threads at the top of the battery tube. Is there a fix for that? It works fine with AW flat tops but those have an unbelieveable short lifespan with this thing,


The other issue is battery life. Do you really have to switch it to lock to keep it from continually draining batteries?

Anyone have the gyroscope quit working, I can't change wattage or setting. In contact with seller but it was ebay so my odds are slim (even though it was new.) Hoping there is a simple fix folks know of. I had just ordered AW batteries since they are the only ones that fit the darn thing.

After sitting without a battery and trying again it appears the gyroscope started working. This may be a trouble spot to keep an eye on for other users.

I've not heard of anyone having a problem with the gyro's in these. From everything you have posted your unit is a dud.

Hope you have luck with the eBay seller. I usually hold of providing feedback on eBay purchases until I know the item works as promised. Your situation is a good example for doing just that.
