Light cloaks will take up 10 cargo space, available to ships with up to 250 cargo. Having a charge time of 10 seconds, and a consumption rate of 4 batteries per second will give any ship with light cloaks ~100 seconds of effective cloak.
Charge time is still lower than the time it takes for shields to regen, leaving cloaking bombers to continue being perfect for constantly restocking and re-engaging throughout a single battle. Would rather see it upped to something like 20 seconds.
