Mugen maybe one of the toughtest buggy ever, realy good for noobs and good basher too
What you plan to do? Do you want sick fast car or reliable race buggy?

For racing 4S is enough. If you want race with feeling that you have enough power to burn any nitro go 5S. 6S is waist. on 60m 2200KV motor
For battery i recommend no go much over 500g weight.
On your link is 3S bat or you plan to use it in series, if yes too much weight ~700grams
Once more: with polyQuest you cant go wrong. Every PQ bat from 4000mah feed your buggy easily. Avarage amperage what buggy takes is about 20A only with peaks to 120-130A.
If you go budget Zippy-H will do job fine too, you dont see perfomance in real life. Only maybe in numbers on datalogger.
So continious 100+ Amps is enough
