Hobby Components Lithium...
£2.08The Hobby Components micro charger is a tiny single cell (3.7V) lithium battery charger module which not only incorporates both battery charging protection and control, but also includes battery voltage & current over discharge protection and battery overload protection. Measuring only 27 x 14mm this tiny module can easily be incorporated into low power lithium battery applications.
The charger will accept power from either a 5V microUSB adapter or via a 4.5 to 6V power supply and will charge a connected single cell lithium battery at a rate of ~0.5A.
The battery can be connected via a JST XH-2.54 connector or by 2 large solder pads (BIN + & BIN -).
The module's output supplies the batteries nominal output of 3.7V (4.2V whilst charging) at a constant current of up to 2A (depending on battery and charger specification). An external device can be connected to this output via a 0.1” pitch pin header or via 2 large solder terminals (BOUT + & GND).Supported battery type: Single cell Lithium-ion battery Module supply voltage: 5V via microUSB or 4.5 to 6V via power in header Battery charge voltage max (float): 4.2V Battery stand-by exit voltage: 4.05V Battery charge current (max): 445mA +/- 10% Battery charge termination current: 44.5mA +/- 10% Battery over discharge voltage protection: 2.4V Battery over discharge current protection: 3.5A +/- 0.9A BAT out terminal voltage max (charging): 4.3V BAT out terminal voltage min (discharging): 2.9V BAT out terminal maximum continuous current: 2A Module dimensions: 27 x 14 x 7.5mm

Hobby Components ESP-ARGB...
£7.49The ESP-ARGB is a general purpose RGB+W LED light controller based on the popular Expressive ESP8266 wireless microcontroller. It combines an ESP8266 ESP-07 wireless module with four MOSFET transistors. These transistors are connected to the ESPs PWM output pins making it easy to perform independent power control of up to 4 connected devices. Each transistor can switch up to a maximum current of 2A and a maximum voltage of 12V DC.
