Simple to use Lipo battery charger

The charger is a simple as plugging the battery into the JST connector and a USB port (500mA capable charger). It is designed to be a small designed as possible which is capable of either charging the battery at 500mA or 100mA. This is selectable by the solderable jumper on the bottom side of the PCB.

On board the lipo battery charger is two LEDs to indicate the status of the charging. When the red LED is on the battery is being charged. Once it has completed charging, the yellow LED will turn on. In some cases both LEDS will turn on, this indicates either a battery is not connected or the input voltage to the USB is too low.

The charger has three stages of charging: preconditioning charge, then a constant current fast charger and finally a constant current trickle charge to keep the battery charged. It has a reverse current flow protection of 2uA, so the battery will not go flat if still connected to the charger.

Features:

Compact USB input with high quality gold plated pins for durabilty and reduce oxidation on the pins
Two status LEDS
2mm JST battery connector (selectable between 2 or 3 pin connector)
Used for 3.7V Li-Ion or Li-Po battery with an end charge of 4.2V. May damage battery if not compatible.
Selectable charge current with a solderable jumper. 100mA open or 500mA closed.

I have made three options to buy the lipo charger. You can either buy the bare PCB, PCB with all the components besides the JST connector and all the components soldered onto the PCB.

The micro sized USB lipo charger is designed and full assembled in Australia and made of quality PCB and parts.
