I've been working on a rechargeable battery solution for the Nikon F5 and just finished Version 2.0 of the design. Thought some of you might be interested.
Fetaures:
Been using it for several months now and it works great. Charges overnight and easily powers the F5 through multiple rolls. The BMS handles balancing and protection, so it's much safer than rigging something without proper battery management.
Files and instructions are up on Thingiverse if anyone wants to build one. Fair warning - this involves lithium batteries and spot welding, so it's not a beginner project. But if you're comfortable with that level of DIY, it's a solid upgrade from hunting down expensive original batteries.
