I've reverse-engineered the FX-BMP port, and now I've built a cartridge to use it - the PC-FX nvBMP !
This is a FX-BMP replacement which doesn't need to use batteries. The original ones are actually REALLY expensive on eBay etc., although with the semiconductor shortage, this cartridge might not be all that much cheaper... although it won't need batteries, so it won't mysteriously lose your data when you aren't looking, and you won't find corroded battery junk inside in a few years' time.
Additionally, the FX-BMP is a 128KB cartridge; this one can accept larger memory chips if you so desire (and can afford them). MRAM (magneto-resistive RAM) chips are in use here, which are available in 512KB and 2MB sizes as well.
The GitHub repository is here, and includes all the plans including designs for an enclosure which can be printed on a 3D Printer::
