I understand how 1x1 fights works (for the most part).

But how does fight between flotilas works?

Sometimes may spaceships are shooting, sometimes they just derp around. How does it work? 

what weapon are those ships using the weapon might be out of range

What is the range between flotilas?

Weapons don't have a maximum range any more - all weapons fire (perhaps innacurately) at all ranges.

• Weapon Balancing:

  • Complete rebalancing of weapons to create more interesting play:

    • Kinetics now have an accuracy of 10% / 50% / 85%, playing a role of missile counter and strong short range damage

    • Missiles now have an accuracy of 100% / 50% / 25%, strong long range damage that can take out most Energy ship designs

    • Lasers now have an accuracy of 50% / 100% / 50%, with good damage. They will tend to defeat Beams and Kinetics, but will have a problem against Missiles

    • Beams now have an accuracy of 100% / 100% / 100%, with standard damage overall. They are sure to hit and will counter Kinetics. Their accuracy makes them perfect to use with counter tactics, and their critical hits can turn the tide of battle in your favor

    • Buffed "Advanced MAGGIE Laser": Now has +100% Damage against Shields

    • Buffed "Advanced HELL Array Laser": Now has +100% Damage against Shield

Long, it seems.
