2- i read thats better to connect the batteries in series, if i get a battery with JST-XH charge >plug this cable is compatible?
That’s a bullet connector, not JST-XH. JST-XH is normally what is used for balance charging (comes with the battery packs you listed). Your packs come with a bullet connector header so it should work. You’ll want to make sure your VESC has bullet connectors as well.
3- which is the best switch on-off compatible with my vesc under $50 ? or i can avoid this >part and plug in-out the batteries?
