what is the best/worst battery in KSP?

[AlamoVampire]

worst battery: the one that fails you.

best battery: the one that helps you succeed.

Z100 for the indicator light (Using a mod to recolor the indicator based on EC%)

Z200 stack beneath docking ports to act as a shock absorber when mashing ships together.

Z1k or Z4k depending on rocket size for actual electricity storage.

I actually rather like the design of the Z-400, it looks robust and reliable and looks good on rover chassis IMO.

I love the 4k, strap a tiny reaction wheel and a command chair to the top, add a pair of ions and some xenon and you can land on any vacuum moon or planet in the game except Tylo.  Add a docking Jr to the bottom and you can drag extra xenon for Moho transfers. And what a view!

Z200. It has enough capacity for all my needs (since nearly all my interplanetary ships have ion engines and therefore need solar panels. Those aren't many) and it's small enough to be stacked in service bays.

Just like the other threads but this one is about batteries! Pointless!

I think the worst one is the Z-100 because it looks like crap. I only use it begrudgingly if design constraints necessitate it.

no it is the best. the bigger once cost more per charge and have the same weight/charge ratio. 

name	charge	weight	cost	weight/charge	cost/charge
z-100	100	0.005	80	0.00005	0.8
z-200	200	0.01	360	0.00005	1.8
z-400	400	0.02	550	0.00005	1.375

so the Z-100 is actually the best of the 3
