8 Flashing LEDs, each with its own 105Ah 3.2V LiFePO4 cell.
Good morning, all as a way of showing that um all eight of my 105 amp hour, lithium-ion phosphate batteries have now arrived. I thought i'd build this 8-bit supercomputer. Well, you wouldn't you so these are they litter carla, 3.2 volt, 105 amp hours got all eight of them now ready to build a big battery pack. So how long will these batteries keep these leds flashing, for, i think at least a year? What do you think cheerio.
A bit over a year. SOmewhere around 400-475 days depending on actual current draw and other factors.
Depends upon how inefficient your LED flasher is.
A LM3909 can flash a LED for over a year using a single C cell.
1.49 years….cheers.
I just looked up the price of those batteries. I'm guessing that you purchased all of those from AliExpress?
Red led consume near abut 20ma. But this blink 50% means 10ma. So as per calculation. (100000/10) *24=416 days..
A long time, that's for sure. 🤪
Very interesting, I would say ~500 days
Not terribly practical for mobile applications!
Guessing those LED's are around 20mA… I'd do a wild guess it's over a year. Maybe year and a quarter more or less. (if you keep them blinking.)
I would say about a year. I will also say that I don’t know what the end purpose is here, beyond seeing how long these batteries can keep these LEDs going?
