Lipo Battery Charger Circuit

[Richard230787]

1st Time I’ve posted here so please be kind.
I want to use a Qi charging system to be able to charge a 18650 2600mAh Lipo battery, (SKU CEO4624) through a LIPO charger like SKU CEO8374. I then want to run a series of led’s from the battery. Can i connect these to the charger. Rough diagram if it helps.

Thanks

Richard

Hi Richard, Welcome to the forum!

You can certainly power LEDs from the 3.3V regulator on the board if you don’t want changes in brightness due to the battery slowly draining.

Powering a string of many LEDs can be a little difficult though, see my post here:

Multiple POLICE flashing LED's

Hi John, Driving that many LEDs isn’t quite as simple as plugging them all in, I found a good article on the two approaches: https://www.arrow.com/en/research-and-events/articles/let-there-be-light-working-with-leds-in-parallel Basically you can either add a boost-capable IC to drive many LEDs at a time in series, or try and characterise your LEDs to drive them in parallel safely. As far as Arduino choice, It’s all about how many different things you want going on at a time. Obviously each p…

How many LEDs were you needing? What colour were they (a hint to get an idea of the forward voltage)

Thanks for your reply John,

Looking at maybe using 3 x 5mm LED’s clear white.

Specs for these are:
