Hello all. I have an LED strip that pulls no more then 3A @ 5v, I was hoping to power them with the most voltage to get them the most brightness, as for the type of led they are WS2812B and each has its own tiny capacitor.
18650 lion 3000mah 2.5v-4.2v range that states it has Max, 15A discharge current, it also has over discharge protection.
I’m using 5v step-up U3V70F5 Voltage regulator
But it seems when my load is connected it drops down the output voltage from U3V70F5 drops to around 3.8v
with no load connected the battery was resting at 4v
3.2v input voltage from battery to U3V70F5 and 3.8v being measured on the output. 3A of current being drawn from the 18650 side and one can expect to see the voltage drop when under load, and only 2.5A being drawn from LED side set full brightness steady on white where can expect the most load.
Can anyone explain what is happening to my output? I was aiming for steady 5v supply for max brightness to my led strip.
