I have a question regarding FT02 vs FT03, I understand the FT02 uses a proprietary (unknown) firmware that has ramping and groups mode (much like but not exactly the same as Sofirn’s proprietary ramping + groups mode drivers on their SP32A/C8Fv2/C8G/SP70).

You mentioned the FT02 has a better driver (more efficient since it uses XHP35-Hi and uses a boost driver?).

I’m wondering about the “worse runtime” — is that mainly due to it having a regulated constant current consumption?
From my limited understanding, FET/direct-driven drivers usually would also be supposedly less efficient — so they would also have worse runtime…
So my question is: would the FT02 or the FT03 have worse runtime? Or maybe better is, under what scenarios will one have better or worse runtime than the other?
