We already reported last month here that Nitcore annouced the new Nitecore NC-BP003 (equivalent to the Fujifilm NP-W235 for GFX100S and X-T4) and NP-BP004 batteries (equivalent to the Fujifilm NP-W126S for most Fujifilm X cameras).
- Nitecore NP-W235 (for X-T4 and GFX100S)
- Nitecore NP-W126S (for most other X cameras)
Now you can find both batteries on Amazon, with the Nitecore NP-W235 already shipping and the Nitecore NP-W126S listed but not shipping yet.
