Associated battery cradle is 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!
