I've only been using my 510-T system for a few weeks and while I'm very pleased with its ease of use, I can't transport filled tanks very well without leakage so I'm hoping I can use my 510-T 280mAh batteries with cartomizers for when I'm travelling or on-the-go. Is this possible? If so, can you please suggest a specific product that is compatible with the Joye 510-T battery 280mAh? Thank you!
