Weight imbalance between "Small Batteries" and "Small Atmospheric Thrusters"

I've been working on small grid start up design for the last 3 weeks and run in to a problem that simply could not be solved.

I had some issues with weight and power to the thrustors and have tried to solve the problem by adding more thruster. Now adding more thruster means that I needed more power to avoid overpowering the power grid. Because I need more control over the shape of the small vehicle I used small batteries. Now adding small batteries made the ship heavier so I had to add more thrusters that also have their own weight to them. More thruster then needed more batteries and so on... The problem never solves itself before you start adding "Large Small grid Batteries" that completely messes up what I trying to achieve. Because there is no information about weight, It's becomes a never ending and time consuming problem that has cost the better part of three weeks just to come to the conclusion that this yet an other build simply can't be done in "Space engineers".

The solution is that ether the batteries need to get lighter or the thrusters need to get lighter and stronger.
