This little identified battery from a now potentially defunct firm will work best with AiroPro. We do disclaim here this battery wasn't suitable for AiroPro, created by CCELL nor intended with AiroPro in mind. We just had an AiroPro battery go negative once which was lying around and it worked. https://real-uk-id76584.ziblogs.com/33455160/the-smart-trick-of-airo-vape-carts-referral-bonus-that-nobody-is-discussing
