What does a battery circuit board do?

The circuit board is, most likely, a battery management system to ensure that batteries are charged in a balanced fashion. When each cell reaches a predetermined voltage (indicating sufficient charge state) that cell is effectively bypassed for the rest of the charge cycle. This prevents over-charging and resultant damage or fire. Figure 1.

Does the battery pack contain a circuit board?

Apparently not; besides the essential Li-ion batteries, the pack contains a 4-inch circuit board, possibly a logic board or microcontroller. Obviously there's no mention of this in the manual and by opening the battery pack I have voided warranty, waived liability of the manufacturer, bla bla bla.

Can Arduino boards work with lithium ion & Li-polymer batteries?

Arduino boards with an onboard battery connector can work with single cell 3V7 Li-Ion and Li-polymer batteries. The VIN pin in Arduino boards is a power pin with a dual function. This pin can work as a voltage input for regulated external power supplies that do not use a barrel jack connector.

How to power an Arduino board with a 9v battery?

For example, you can directly connect a 9V 6F22 battery to the Arduino through the barrel jack using a 2.1mm connector or directly to the Vin pin using jumper cables. these are the commonly recommended methods to power an Arduino. How to Power Arduino boards with a 3.7V lithium battery?

Which Arduino boards have an onboard battery connector?

The Arduino boards with an onboard battery connector are the following: Pro family boards use a 3-pin, 1.2mm SMD ACH battery connector; MKR family boards use a 2-pin, 2mm SMD PH battery connector. Battery connector of the Arduino MKR WAN 1310 board. The boards mentioned before have an onboard integrated battery charge management circuit.

What if a circuit is not connected to earth ground?

Circuits that aren't connected to earth ground must have a floating ground. Floating ground really means a 0V reference line. As an example, let's take the circuit shown below. This is a circuit powered by a 2 AA batteries, giving a total voltage of 3V in order to light up the LED. Circuits powered by batteries do not have an earth ground.
