Hi everyone,
I'd like to build the Florabrella.
Looking at the recommended battery (3.75V 2500mAh), I'm unsure:
How about the running time? 150 LEDs * 20mA = 3A. So the battery should be empty in less then in hour right?
What do you think of using an Arduino board and 4x NiMH cells as suggested here https://learn.adafruit.com/battery-powe ... -batteries?
These cells are readily-available, easy to recharge and can provide up to 4x 2500mAh. Sounds like a better option to me. Can I just add up the battery capacity to 10.000mAh?
Thank you for your suggestions!
Best regards, Simon

Re: Florabrella battery running time
Current draw depends a lot on how they are programmed. There are many techniques for extending the run-time of your portable Neopixel projects:How about the running time? 150 LEDs * 20mA = 3A. So the battery should be empty in less then in hour right?

It doesn't work that way. Wired in series, you multiply the voltage, but the current capacity stays the same. You will get 4.8v @ 2500mAh.These cells are readily-available, easy to recharge and can provide up to 4x 2500mAh
If you want more capacity, you could switch to a higher capacity LiPo cell:
