This is a optional Team Associated Factory Team LiPo Battery Cradle, intended for use with the Associated B44.
The Factory Team LiPo battery cradle replaces the Team Associated's B44 stock NiMH battery holders so that LiPo batteries can be installed securely without messy double-sided tape or adhesives.
Specifically sized for use with Reedy's 5100mAh (#710) and 4200mAh (#712) saddle pack LiPo batteries, the cradle is CNC machined from light and durable 2.5mm woven carbon fiber. With internal dimensions of 68.9mm x 46.9mm, other hard case LiPo batteries that fall within this measurement can also be used.
Installation is as simple as removing the existing battery trays, loosening a few screws, sliding the cradle into position, then re-installing the stock posts and straps. A simple modification to the side body mounts is also necessary. The result is a B44 that looks like it came LiPo-ready from the factory!
