Will this work for, e.g., building a custom (DB25) serial cable?

I used this crimper to build DB9 and DB15. It does crimp both male and female dsub pins. Quite nicely too. I would recommend having a couple of dsub pin extractor/insertion tools on hand when building the plugs...

Can I use SN-2549 for bouth jst xh2.54 and jst ph2.0 ?

For perfect crimping, I suggest you to use SN-01BM for PH2.0 and SN-28B for XH2.54

Does this work with 2.8mm car motorcycle electrical connectors? https://www.amazon.com/dp/b075ldmnwk

I suggest yu to use SN-2549 or you can send image or technical data to me for confirmation .

Will these work on jst-xh connectors for lipo battery balancer terminals?

Yes, it can work with JST-xh 2.50mm connectors.
