how about we have some racing battery. like recharge of 55 and hold of 10 or something

How about a hold of 60.
Not that you need a battery for racing but yea sure do it.

Heh. I'd put that in my Valk Vengeance and you'd NEVER catch me. Mostly because I don't turn and fight if someone attacks me :D

(approved)

then flares would become even more powerful.

require that you carry no weapons while the battery is on board and you'd be all set

Sounds great for even faster infini turbo trading, which a lot of people don't seem to like already.

well if wormholes required a finite amount of jump energy, say, 200, then a racing battery with 1, 10, or even 199 capacity would be utterly useless for anything other than in-system traveling and racing. (to clarify things a bit more, regular in-system jumps would cost less, or something, maybe 175 or something, so that the battery could at least allow jumps between sectors.
