Maxwell 650 Farad 2.7v Ultracapacitor

Just playing around with some ultracapacitors, charging them up with a 2.5 amps power supply, until it starts to smoke.
They are connected in series, you can easily see them charging up on the voltmeter, they can be charged up even faster with a better power supply (one that wont start to give off smoke)

How much did that cap cost? Would love to get a bunch of them.

[Auhydride]

25$ each

Two caps times 2.7V each makes 5.4V, half capacitance.

@TankCrusher210 actually right now 1 cap for 9 bucks i just bought 1

@likmahchoda FYI, Electronic Goldmine is selling 2600F BoostCaps right now for $20.

@Auhydride oh. okay...cool.

[Auhydride]

@waterwart oh, each capacitor can hold 2.7V, when connected in series, as long as both of the capacitors were properly balanced (both of them must be at the same voltage at the start) the total voltage can reach 2.7+2.7=5.4V and it won't damage the capacitors as the voltage of each capacitor isn't over 2.7V

[waterwart]

@Auhydride uh? can you dumb that down a little? What does that actually mean?

[Auhydride]

@waterwart there are two in series

[waterwart]

@yakir11114 Is that true? What did you base that claim on? Just wondering (inquiring minds want to know).

is the power supply need to be dioded
