pcb power connector lipo
This probably (I assume you searched a while and won't repeat that) a wire to wire, not a wire to board connector, so you are indeed not going to find one intended for mounting on PCBs. You should instead choose any appropriate (mainly current rating and mechanical sturdiness) wire to board connector and make an adapter cable. Making your own cables is by crimping is very straightforward and can save you a lot of trouble with mismatched lengths etc.
Alternatively you could cut the cable (not both wires at the same time though!) and fix a different connector on it. 

Basically you should choose one or two kinds of connectors appropriate for your needs, buy a cheap crimping tool, wires in different colors and a handful of said connectors and crimps. This will save you trouble in the long run. 
It is probably a good idea to buy both the same connectors your PCBs have and a good wire to wire connector. 

If you need help doing those things just ask another question.
