External charger for the FP2/3

Hello, is anyone still interested in an external battery charger for the fp2, maybe the New fp 3 ?
I could realise this idea quite easily, as a side project to my New bottom module, which still needs a New Revision.
I could do that if there’s demand for such a product, price would be 20-30€, depending on the demand.


Question regarding terminology … it’s not something like the readily available universal external battery chargers?

No, it’s specificaly for the FP, the universal ones also don’t monitor the battery Temperatures, which could in theory be dangerous if the battery overheats, they also have a different charging current.


I’d actually love one for each FP model. Or each that you make one for.

I don’t know, I could make the PCB universal and just print different cases. I would need a fp1 and fp3 battery then, or at least borrow one, I don’t like the ones where you can slide the contacts, as you could easily damage the battery by accidentally sliding them and creating a short circuit. My charging IC has all the important safety features, including over current, over voltage and most importantly over temperature protection, I would make it so you can plug it in via u USB or USB C


How many people are there, that would actually buy one ? I know I’m known for doing stuff like that, but that stuff costs monney. I have to be sure that when I spend my time and monney in that project, that there will actually be people out there buying it.
