Perfect for longer run times
These adapt the Letus Helix Jr. to use the larger JuiceBox 5200 batteries, a godsend when using the Helix Jr. with 'larger' setups like the Sony FS5. Easy screw-in replacement for the standard battery posts, and holds the batteries securely. My only recommendation for improvement would be to make the cage-side thumbscrew a captive screw... I've already nearly lost it three times in the field.
