how do I increase capacitor level to handle more than one gun?
you need to put cap batteries in your mids
power diagnostic systems in your lows
and semicondctor memory cells in your rigs
you should be able to reach 8000 capacitor
Do you mean capacitor, or Powergrid (which is used for fitting guns).
I have also replied to your other forum post with some tips.
you can put capacitor batteries in mid slots and put power diagnostic system in low slot. Pow. dig. in low will boost several things, capacitor capacity is among them.
Explain your problem.
With medium skills you shouldn’t have cap problems to install most of available guns (except smartbombs), but you can have powergrid problems.
In general you have 3 options:
Increase your cap level as was explained by JC Mieyli (is good when you need to fit high cap modules, which you’ll use time to time);
Increase your cap recharge speed (is good when you need to install low cap modules , which you’ll use frequently - active mode);
Upgrade your skills to have more cap on the ship and consume less cap with installed devices (Engineering, Shield, Gunnery).
