I don't know if IB has a website; you'll have to check it out. I do know that both Traxxas and Dynamite sell batteries that are manufactured with top quality IB cells. You can find them both at
www.towerhobbies.com. They are a fair price, last forever, and don't lose performance at all if they're properly taken care of. I've run mine many, many times and have lost no performance. I would guess they have over 100 runs on them and still work like new. I've heard the
www.cheapbatterypacks.com EP (Elite) cells are also of very high quality, but I have no experience with them and can't say for sure. Good luck!
