I've had pretty good luck with KASTAR Npfs -- https://www.amazon.com/Kastar-Replacement-CCD-TR415-CCD-TR416-CCD-TR425/dp/B07GT2YBDR/ref=sr_1_11?dchild=1&keywords=large+npf+battery&qid=1598992093&sr=8-11
And a HDMI like this -- https://www.amazon.com/Poyiccot-Cable-Degree-Plated-Speed/dp/B0733286KP/ref=sr_1_7?dchild=1&keywords=2ft+hdmi+2.0+cable&qid=1598992255&sr=8-7
And a SSD cable like this should cover you for all the accessories they offer in the Atomos bundle minus a case -- https://www.amazon.com/Drive-Adapter-Cable-Support-Black/dp/B07S9CKV7X/ref=sr_1_3?crid=TASQ61XKI7EY&dchild=1&keywords=ssd+to+usb+adapter&qid=1598992298&sprefix=SSD+to+u%2Caps%2C189&sr=8-3
But these work great for monitor "cases" -- https://www.amazon.com/MoKo-Paperwhite-Protective-Neoprene-Generation/dp/B07FCC4BV9/ref=sr_1_2?crid=2F7GC1VSABHBY&dchild=1&keywords=kindle+neoprene+sleeve&qid=1598992350&sprefix=kindle+neoprene%2Caps%2C182&sr=8-2
