DIY LiPo Supercharger Kit V2 (by GreatScott!)

This DIY LiPo Supercharger/Booster (developed the electronics engineer/YouTuber GreatScott! and produced by Elektor) can charge a single-cell LiPo battery and protect it against the effects of overvoltage, overload, and short-circuits. Additionally, it can boost the battery voltage to 5 V or 12 V. The boosted output voltage is protected by an ‘eFuse’ IC outputting 1.52 A at 5 V or 0.76 A at 12 V maximum.

The charger part of the circuit needs a +5 V power supply which can be connected through USB-C, or simply two wires soldered to pads on the PCB.

In addition, other connections can be soldered to pads on the PCB or by using single pinheaders.

Included

• 1x Mainboard pre-assembled with the 4 ICs
• 15x Resistors
• 3x LEDs
• 13x Capacitors
• 2x Switches
• 1x USB-C on a breakout board
• 2x Diodes

Please note: Battery is not included.

The board uses a DC/DC Converter, an IC charger, and an e Fuse from Texas Instruments. The battery protection IC is from Xysemi and provides under-voltage lockout, over current protection, and reverse battery protection.

The board is connected to the power and recharges the batteries via a USB-C connection.
