A little help with Personal Gear?

[La Criatura Espada]

I need some help with optimization. I got 5 P. Batteries mk2, 18 Solar Panels, a Belt immunity equipment, NV, and 2 exos. I'm not sure how good these batteries are, and I'm guessing I can replace some with more panels to charge what's left.

Since you only use "passive" modules it should be easy to figure it out.

During the day, you are using 100 kW for the belt immunity and 2 times 200 kW for the exoskeletons for a total of 500 kW.
During the night, you add 10 kW for night vision.

It means an average of 505 kW of consumption.

Each solar pannel gives 30 kW (it used to be 10), but they only work during the day, so you need to roughly double the amount.
2*505/30=33.6666...
This means that you can't possibly power your current gear without putting 34 portable solar pannels.

On top of that you need to store half of that power for the night, they each store 100 MJ, and you would need to store about:
505*209 (time in seconds that is not "day") = 105,545 kJ = 105.545 MJ
If you account for the internal charge, a single battery mk2 should be enough (if I didn't mess up with the math).

This would not fit in a power armor mk1 or modular armor but it should fit in a power armor mk2 (it requires 56 slots if I didn't mess the math, mk1 has 49 and mk2 has 100).

Still, you might want to try to get a portable fusion reactor, it takes 4x4 and provides 750kW, which is more than enough to power what you want.

I overstocked on batteries. Wayyy too much. In my Power Armor I managed to fit in a roboport too, don't run out of power at all.
2 Exo, NV, Roboport, belt immunity, 2 Mk2 batteries and 20 solar panels seems to be a good fit for me.

at one time there was a need for multiple batteries. then Wube buffed them. (20 fold?)
i never need more than one battery.

Well, when using personal laser defense and shields batteries aren't exactly bad to have, but for passive gear like that you only need enough to ge through the night.
