Battery rod weights for Ultra2 sled and alternatives for adding counterweight
14 years old. Gear and prices may have changed since.
What the thread found
- Battery rod weights (800-7617) connect via female threaded holes that screw into male threads inside the battery rods, with no play when properly installed.
- These weights fit snugly into Ultra2 battery rods, though they may require camera tape around them to achieve a snug fit in Clipper models.
- Alternative methods for adding weight to a sled include placing a dummy battery at the bottom via dovetail mount, using weight plates with an IDX battery mount system, or installing a third battery mount that can swing adjustably between positions under the post and toward the monitor.
- Weight rod inserts and bottom-mounted battery systems have different trade-offs: internal rods keep profile compact but limit customization, while bottom dovetail mounts add volume and may prevent use on flat surfaces like tabletops.
- Tiffen stopped manufacturing the battery rod weights, though the factory may still have stock available.
Depends on
- No specific technical dimensions provided for rod diameter or thread size.
- The adjustable angle third battery mount system described was shown as a modification example but no images or detailed specifications are available.
- Experience with these weights is limited to anecdotal reports from users; no systematic testing data on vibration or long-term reliability.
- Unclear whether all modifications work identically across different sled models.
