Unregulated dual 18650 serial mod - fuse question

[avpx1]

Hi All, I'm about to embark on my first DIY unregulated box mod running dual 18650 batts in serial. I am building my box as shown in this schematic (not mine but not sure who to give credit to either). I'm unsure about exactly what fuse to use? Can you please share your recommendations on the fuse type and rating or even a recommended part from mouser or digikey? Would really appreciate the feedback. I've been able to spec out all the parts except the fuse. I'm excited to get this going but need to get my ducks in a row first.

The fuse should be on the positive battery, not on the negative at the connector.

16 amp resettable.

Thanks SupplyDaddy. I updated the picture to reflect the changed position. The advice is appreciated.
