Setup this quickly in EFT for Mac (Akamine). Its a basic, totally t1 (I'd go with best named T1 to make it better and lessen the overall requirements) fit for the Level 2's you are currently doing.
Cap lasts 5 minutes I know, but thats based on guns going all the time, in alot of L2's you can leave your drones or missiles at it.
It as an EHP of 31k - quite the buffer tank really.
The hardeners can be switched out to others to counter rat specific damage and the missile launchers can be changed out for heavies or standards - depending on the majority of what you'll face in missions.
Or you can totally passive and not give a care about cap usage and cap recharge time:
