I didn't think I could use a one battery mod anymore. I didn't for over 2 years. But the Aegis has everything I was looking for except it was just a single battery. So I bought one anyway to give it a shot. And to be frank, it sucks with 18650 25r batteries. Those batteries are only good up to about 70 watts anyway. And battery life was pretty short in the Aegis. So it was pretty much what I expected from a single cell mod.
I only had one mod that can use a 26650 battery years ago and I only ran 18650 batteries anyway. So I have tons of 18650 batteries, but no 26650s. Went shopping and looked at Mooch recommendations. And Mooch recommends Aspire, iJoy, Golisi, or Vapcell. Found an eBay seller that claims they buy Aspire batteries from Aspire directly. And this seller test the batteries to make sure they are up to specs. And Aspire pulse specs are 10s on and 5 seconds off at 40A for their Aspire 26650 4300mah. So for vaping, we are talking about 3.7v*40A which equals of delivering up to 148 watts max. Which is more than enough to power the Aegis.
So I bought some and the Aspire battery has no problems delivering whatever the Aegis wants. And the battery last about 70-80% longer than my Samsung 25Rs. So it isn't quite as long lasting as two 18650s, but it comes pretty close. I was so happy with this, I bought two more Aegis mods.
