Battery with charger

There will be series of simple(r) circuits for my new electronic course for elementary school. For start we need power source. Batteries are fine until flattened out, therefore it’s good to have rechargeable one. I took MCP73831T-2ACI/OT, added micro USB connector and switch to select between charge/discharge mode. In the charge mode, the output is connected to +5V input supply. The power is delivered to the charger via micro USB connector, which means eny mobile phone USB supply will do the job. The charge current is limited to 2A and battery cell has integrated protection circuit. I will add 3D printed housing for the complete pack after the testing of first prototypes.

I am one of them and you can probably tell where I got the idea to make the LED shades.¬†Projects like this one don’t just keep me occupied in my free time but are also designed to broaden my knowledge in electronics and programming.

Single LiPo cell protection and charger

Single cell lithium polymer battery cell is very handsome power source for many applications. Unfortunately it is quite dangerous when such battery cell is not properly protected and charged. I prepared simple 1S LiPo battery protection and Charger on two, single sided small PCB modules. I separated Protection from the charger when only protection is needed.
