If it's not a tank v tank battle - get out, swallow your pride and save your bank balance. So what? If this does happen a lot, invest in kinetic-biased armour to buy you time and two pods of chaff.
This has only happened to me once bear in mind, that was an FDL with lots of kinetics too. I was doing a community goal for combat bonds so I was armed to the teeth. So running a hot python going for big game, 3 large bursts, 2 med turret cannons, armoured and reinforced. It's a battle-pig. 2 chaff and point defence, boosters & A-rated. It's packing.
Set your speed to 0 and let them to the work. Use impulse to keep a safe distance, most kinetics are not great at 2.5km. Plug away with lasers, set up laterals and impulse to get a drift on if you like but there's little point. At that kind of distance, it'll make little difference.
It's a pure attrition tactic, nothing more.
Despite armour, armed (3 large bursts and 2 cannon), two pods of chaff. It was an SCB battle royale until they ran out. I was down to about 12% with a blown canopy, they were suffering on 6%. They bugged out and had a 2.5km headstart. High wake... poof... gone.
