A single 700 mAh 14250 battery lasts about 24 hours.
The TP4056 prevents the cell from being completely drained and should protect it from damage.
Altough it's not included in any of the the pictures or schematics, both the case and the back cover are updated to include a slot for a micro slider switch (SPDT), in case you actually want to have a power switch instead of letting it run untill the battery drains.
Although it's not shown in any of the pictures or schematics, both the case and the back cover are updated to include a slot for 8.5mm SPDT slider switch(SS-12D00), in case you actually want to have a power switch instead of letting it run until the battery drains.
* Solder the 14250 battery to the **TP4056 input pins**.
* Wire the **TP4056 output** to the **3.3V pin** on the D1 Mini to power the device.
