My new Giant Twist Freedom's single battery pack has a lock to secure it in the holder to prevent battery theft. It has a flaw. At a local bike meeting a large man showing interest in the bike was curious about the battery. He lifted it out with the handle that levers the battery away from its holder, and it came right out although it was still locked. Upon examining the lock at home, i discovered that the lock operates much like a door with a wedged tang that slips into a notch on the battery. However! The large cyclist who easily lifted it out, apparently split the case (easily it seemed) so that now the frame of the flimsy plastic holder merely spreads so one can lift the battery without unlocking it.
I would like to let Giant as well as others know about this but the company, unlike Dahon, seems uninterested in promoting community nor in providing a means of contacting them. I like the bike but am put off by the indifferent nature of the company toward customers.
I have not figured out a fix for the problem but will post here if I do.
Since it's new, it should be under warranty. Contact the merchant you bought it from, they may be the ones who have to deal with Giant. Giant does have it's contact information online, but I don't know if they're responsive to consumers. This is the listed contact info: Giant Bicycle, Inc.

I installed a Currie conversion kit this summer. It has a rack mounted battery case that locks, too. The locking bar is fairly good-sized, but the battery box is plastic so I suspect a determined thief could get it out. The Currie battery isn't LIFEPO4, but just SLAs so it wouldn't be as attractive a target.
Good luck. That bike wasn't cheap and Giant should make things right. (How big was this bike enthusiast? I'm glad my battery case is obscured from view by my panniers.)
I bought the bike in Tacoma, WA and live in LA so I hope someone local will honor my warranty. I'm glad for the national numbers.
This cyclist was so big he did not even notice any difficulty lifting it out. Part of the problem is that the handle is designed to lever the battery out rather than just lift it. It therefore, spreads the top of the plastic holder when forced.
