Yes I would rather 2.5v version with lower capacity. Rather than risking popping a capacitor. So will be looking to replace mine. What is the part number for the 2.5v IC? .
Bear in mind that the the data sheet for a 500F one was looking at today, gives the upper voltage limit of 2.85 volts. Seems they can tolerate quite a bit more that 2.7 Volts
I am sure the max voltage is way above nominal 2.7V of these supercaps. If so then 108% (takin max of nominal and hysteresis) would be 2.91V – still probably below the voltage of the capacitor to blow. On the other hand if this sensor detects exactly 2.7V to start charging it, then the capacitor would be always between 2.7-2.91V – not bad, just 10% of the U nominal
Hi. can i use this particular capacitor pack for my bike starting without much customization. bike is 12 v. i cannot use battery as i barely use bike. battery ends up dying.
In the data sheet's OPERATIONAL EXPLANATION, hysteresis operation is made a bit confusing in (1) and (5). In (1) where it is stated: when Vin ===IS HIGHER=== than Vdf, then Vout=Vin. and in (5) where it is stated: WHEN Vin ===RISES ABOVE=== Vdr, then Vout=Vin.

I'm rather surprised at not seeing any inclusion of the datasheet for the capacitors in this…
Could you use the 3v super cap instead?
We need it to work at 48v and 20ah

Watching the time on the video says you had just under one minute of light.
Very aesthetic!
