This is a simple arduino based "smart" charger. It will drive and report statut of 3x TP4056 boards, with built-in protection if you can.

Additionnaly it will manage a current budget, i.e. make sure the total current consumption does not exceed the maximum (2A by default). Charging will be delayed until the requested current is available.

Components short list :

• Nx TP 4056 with protection circuit (o TP4056 + separate battery protection circuit)
• N* P Mosfet
• INA3221 ( or N* INA219)
• 1 arduino
