Li-ion Battery HAT
From Waveshare Wiki
| ||
Introduction
- The battery needs to be inserted into the module, the switch is turned ON, charged for about 1 minute, and then disconnected, the module will output normally, otherwise, there will be no output.
- If the battery is pulled out, then you need to operate again.
- This module cannot be used as UPS (uninterruptible power supply), if the battery voltage is too low, it will shut down the Raspberry Pi system.
- You can use the micro USB to directly power the power supply USB port of the Raspberry Pi.
- Because the height of the module itself is already very high, it is not possible to stack other modules on top of the module.
- Do not over-discharge lithium batteries, due to the characteristics of lithium batteries, over-discharge will permanently damage the battery.

Operation Effect
- Operation Note:
- Insert the module into the GPIO header of the Raspberry Pi, and it can supply power to the Raspberry Pi. The switch on the module can control the Power On/Off for the Raspberry Pi.
- Insert the module into the GPIO header of the Raspberry Pi, that is, supply power to the USB Type-A interface. If the module is not inserted into the Raspberry Pi GPIO headers, you can use a USB cable to supply power to the Raspberry Pi from the USB Type-A interface.
- Warning LED is a battery reversal warning light, then you need to pull out the battery and turn a direction, and then connect it to the module. Do not connect the charging cable when replacing the battery. After replacing the battery there is no power output, you need to charge it to have power output.
- There are 5 power indicator LEDs on the module to show the battery status.
- The Quick Charge LED is a fast-charging status indicator. Only when charging with a charger that supports Quick Charge, charging with a normal 5V charger will not work again in the Quick Charge state.
- The battery used in the module is a rechargeable 14500 battery with a nominal voltage of 3.7V, a full charge of 4.2V, and a discharge voltage of 3V. Note: The module cannot be connected to ordinary non-rechargeable 7 batteries.
- Discharge time is directly related to the battery capacity already loaded, use an 800mAh battery to power Raspberry Pi 3B+ for about 50 minutes (Raspberry Pi 3B+ power consumption will be a bit higher than Raspberry Pi 3B), to power Raspberry Pi ZERO W about 2~3 hours. (Raspberry Pi at zero loads).
- Module theoretically can be connected to a larger capacity battery by soldering, non-professionals are not recommended to weld without permission.
SAFETY CAUTIONS
- Li-ion and Li-po batteries are quite unstable. They may cause fire, personal injury, or property damage, if they're not properly recharged or used.
- Do not reversely connect the polarities when recharging or discharging the battery. Do not use inferior charger/charging panel to recharge the battery.
- Do not mix use old batteries with new ones, avoid using batteries of different brands.
- When buying Lithium battery, make sure the battery specification is compatible with the expansion board. Choose batteries from formal manufacturer, and ensure the batteries will work stably and safely by aging test.
- Lithium batteries have limited cycle life, they will also deteriorate as time goes by. Should be replaced with new ones when the batteries reaching their max cycle life, or working over two years, whichever comes first.
- Should be placed carefully and properly, keep it away from inflammables and explosives articles, away from children, avoid any safety accident caused by careless storage.

FAQ
Answer:
After getting the module, you need to charge and activate the battery for a few minutes, and the switch can be turned ON to output.
{{{5}}}
Answer:
The output identification protocol will be disconnected at the moment of charging or unplugging the power cord, so there will be a brief power failure that will cause the Raspberry Pi to restart, and it cannot be used as a UPS power supply.
{{{5}}}
Answer:
The 5V Micro USB is plugged into the module's micro USB port, not the Raspberry Pi's USB port.
{{{5}}}
Answer:
You need to plug the battery into the module, turn the switch to ON, charge it for 1 minute, then disconnect it, and plug it into the Raspberry Pi to output. Check whether the connection is reversed, the reverse connection indicator of the reversed board will be on.
{{{5}}}
Answer:
Yes, just use a micro USB to supply the power to the USB interface of the Raspberry Pi.
{{{5}}}
Answer:
Yes, just use a micro USB to supply the power to the USB interface of the Raspberry Pi.
{{{5}}}
Answer:
Yes, but you need to use a 14500 battery with a capacity of 1200mah.
{{{5}}}
Answer:
You can check the manual of the chip: up to 4A current, up to 96% efficiency.
{{{5}}}
Answer:
Not supported, cannot support Raspberry Pi to read power.
{{{5}}}
Answer:
The battery is 850mAh, 3.7V, converted to Wh is 850/1000 * 3.7 Wh; The static power consumption of the Raspberry Pi Zero is approximately 1.3W, and the full load power consumption is approximately 2.65W.
For instance, at full load, it would be 3.182/2.65h, approximately 1.2h. These figures are for reference only; actual usage may vary depending on the specific scenario.
{{{5}}}
Answer:
If used in standby mode on a Raspberry Pi Zero, it may last around 2-3 hours, mostly dependent on the battery capacity. For instance, with a 3.7V 3000mAh battery, theoretically when fully charged, supporting an output of around 3V with a 3A current load, it might last approximately 1 hour.
