The Zephyr has a 24-pound camera payload capacity but only 30 pounds total lift capacity, which may require post extension or added counterweight to achieve maximum camera load.
The Zephyr was designed with single battery power for the camera and monitor, while the Flyer LE uses two batteries.
Tiffen confirmed there are no plans to offer a dual battery mount for the Zephyr despite it being listed on their website.
A single battery like the Hytron 140 weighs approximately 5.5 pounds and represents the heaviest single battery option available.
Counterweight can be added to the bottom of the centerpost using assembly weights to balance heavier cameras without extending the post.
The dovetail and gimbal are rated for 24 pounds of camera payload, with the rest of the system engineered to handle necessary counterweight.
Battery hotswap plates for A/B or V-mount systems can provide a partial workaround but have their own limitations.
IDX stackable batteries offer a potential solution for users already invested in that battery system.

The single battery limitation particularly affects users shooting power-hungry cameras like RED or HD ENG cameras near the top payload range.
Users with existing investment in non-stackable battery systems such as Anton Bauer face significant compatibility challenges.
The Zephyr's 30-pound lift capacity appears constrained when accounting for a 24-pound camera plus required counterweight, potentially necessitating post extension or dead weight additions.
Website information from Tiffen listed a dual battery mount option that was never implemented.
