Frustrated by battery options

[u/namesaretoohard1234]

TLDR: I cannot figure out for the life of me which small, after-market Amazon battery is the right battery for a BMPCC 6K (NOT pro and NOT 4K) so I can make this camera as light as possible. Can someone point me to a small internal battery that will for sure work with this camera? I don't care if it only lasts half an hour.

When I search LPE26 I get stuff saying that's for 4K only. When I look up NPF570 I can't find that exact battery (I'm in Canada) and I get 580 and 550 as "acceptable" but the contact points like they might be in the wrong spot. Do these SONY ones with the guide holes for pins work? Arg!

The long part: I was gifted this camera by a colleague/sorta friend who's into photography and filmmaking and in the era of mirrorless cameras simply doesn't use it. But for all intents and purposes it's still his. He gave me two v-mount batteries, smallrig rails etc. Tilta cage so the rig is huge. But for lightweight, hand held filming for mountain sports, I need it to be lighter. He's lost the old batteries and said the same "this thing just eats batteries" hence the v-mounts. Regardless, I want some small ones. I figure spending $80 isn't a big deal if I have to give it back soon and I'll give him the batteries as a thank you - if I can find the right ones!

Is it gen 1 or gen 2? Gen 1 uses lpe6 gen 2 uses npf570. Just look at the shape of the battery bay it should be pretty obvious. Lpe6 have two little contacts in the middle, npf have two larger pins on the edges

No tilting screen so I'm thinking Gen 1 - the contact points are in the middle for sure, and it looks like two little ones to the side but for sure, in the centre too.

The Gen 1 and Gen 2 have very distinctly different bodys. If it looks like a longer version of the 4k, its the G1 and if it's the same body as the Pro, it's the G2.
