Hello friends !
I want to make a project with 2 meters of 5V WS2812B led strip.
(60 chip / meter)
4 rows of leds, each 50cm.
I will not use Arduino, I will only use a controller.
But I do not know what kind of battery to use.
(The brightness of the LEDs is important to me because it will be a video light.)
Powerbank, 18650, AA battery or rechargeable AA battery. Which one should I choose ?
I will not use white light mostly. I will use colors such as yellow, orange and pink other than red, green and blue. There will be no animation.
It should not be discharged for 60-90 minutes.
OK, 120 LEDs at 55 mA if full white (and likely to be so on one occasion or another). 6.6 Amps. For 1½ hours that is 10 Ah.
You want a proper 5 V. Find a battery pack of around 12 V with a charger - could be a 3S LiPo or a SLA, rated about 10 AH, and a switchmode "buck" regulator rated 10 Amps (output). It will require only half that current on the input side but you want to generously over-rate the battery especially for a 1(½) hour discharge.
mrjoeblack:
this is just a simple demo, no need to be this harsh. If I can achieve this I will continue with arduiono.
Are you suggesting that if you fail this non-Arduino project, you will eschew Arduinox (or "arduiono"s) just on principle?
