Spaceships Quickie: Power Cell Energy Banks
If you ever built a ship in GURPS Spaceships there's a good chance that you've run into the frustration of trying to balance how many Power Point using systems you have and how many Power Point generating system you can cram into he hull with out compromising something. This can especially become a problem for warships were you usually have to cut something armor to stuff in another power plant or have to cut the number of weapons systems.
Well frustrate no more my most awesome readers! For in today's post I give you guys the one system I think we can all agree should of been in at lest on of the Spaceships supplements:
Power Cell Energy Banks!
In practice Power Cell Energy Banks give you a "pool" of one use Power Points. They store a good deal more Points then any power system generates letting you power far more energy dependent systems for the same amount system spaces, at lest for the short term. They can also be recharged by power generating systems letting you get away with fewer, or with multiple power point system, smaller systems freeing up more room. Of course you are still going to have to think about how many Power Points to spend at any given moment in high risk situations. It may seem like you got a lot of Power Points to play around with but if you spend them to quickly you might find yourself with to short of a supply on hand if a crisis crops up before you can recharge!
So as you can see this system gives you a good bit of flexibility when it comes to managing high power systems. It can also help give some character to your ships if want to put a little extra detail into it. For example let's say you want to have your ship use a jump drive that needs a charge time before it can be used. Lets say you install three Jump Gate Systems needing a total of 3 Power Points to power. You could then install a Fission Reactor system that only generates 1 Power Point a 2 size smaller system TL9 Power Cell Energy Bank system that gives you only 3 Power Points of storage giving you a three round charge time for it.
Alrighty, now on to the system itself. Hopefully you guys find it useful!
Power Cell Energy Banks (TL9) [Any]
A series of large, high capacity, power cells arrange in a bank to store and rapidly discharge power when needed. Each system stores up to 30PP at TL9, 120PP at TL10, 480PP at TL11 and 1,920PP at TL12. Keep in mind that this is only a storage system, each power point used deplete the total stored and can only be replaced by excess power being diverted to it from a power plant or reactor. If you are ok with a little extra note keeping, power plants and reactors that produce less then 1PP can still recharge a Power Cell Energy Bank, it will just take longer. A half sized system will take two turns to charge 1PP, a 1 size smaller system will take 3 turns to charge 1PP and a 2 sizes smaller system will take 10 turns to charge 1PP. You can also choose to use non-rechargeable power cells. These double the amount of Power Points stored but in turn they can not be recharged.

Available as half, 1 size smaller, and 2 sizes smaller systems. A half sized system hold half as many PP, a 1 size smaller system holds 1/3rd as many and a 2 sizes smaller system holds 1/10th as many.
For those using my optional system that let's you deign spaceships of any size, just multiply how many PP a systems worth of Power Cells store for your ships TL by how many pounds or tons of power cells the ship is going to hold divide by the mass of 1/20th of the ships weight.
Example: At 1,000,000 tons, 1 ship system weighs 50,000 tons. If you were going to use 10,000 tons worth of TL11 Power Cell Energy Banks, the system would store 480×(10,000/50,000) or 96PP.
Cost is $100 per pound or $200,000 per ton.
Thanks to Tamahori for inadvertently making me realize I forgot to mention you can choose to have non-rechargeable cells as well.
