Raspberry Pi Li-polymer Battery HAT User Guide

Instruction

The Li-polymer Battery HAT integrates SW6106 power bank management chip, allows providing 5V regulated power supply to your Raspberry Pi or other 5V devices, from a high capacity Li-polymer battery. It will charge the battery as well, supports bi-directional quick charge.

Features

• Onboard SW6106 chip, supports bi-directional quick charge, supports multi quick charge protocols like PD/QC/FCP/PE/SFCP
• Lithium battery protection circuitry, provides reverse protection, overcharge protection, and short circuit protection
• Onboard indicators: quick charge, power capacity
• PH 2.0 battery connector, for connecting the 3.7V 3000mA high capacity Li-polymer battery (MSDS certified)

Specifications

• Output voltage: 5V
• Charge voltage: 5V
• Applicable battery: 3.7V Li-polymer battery (4.2V when full charged)
• Dimension: 65.0mm × 56.5mm
• Mounting hole size: 3.0mm

Interfaces and Indicators

• Interfaces

• There are five battery indicators.

• Quick start indicator

When you connect power adapter to Type_C interface for quick charging, the Quick Charge indocator will turn on. If it keeps on, maybe that your adapter doesn't support quick charge.

• Standby button

Single-press it to output 5V, and double-press it to set it to sleep mode.

How to use

Discharge

Connect it to Raspberry Pi

• Step1: Insert the Li-polymer battery to 2.0mm battery socket.
• Step2: Single-press Standby button, set it to discharge mode
• Step3: Attach it on Raspberry Pi for powering.

For other devices.

• Step1: Insert the Li-polymer battery to 2.0mm battery socket.
• Step2: Single-press Standby button, set it to discharge mode
• Step3: Connect it to other devices by USB cable or wires.

Charge

Charge

• Step1: Insert the Li-polymer battery to 2.0mm battery socket.
• Step2: Connect power adapter to micro USB or Type-C interface by USB cable

Quick charge

• Step1: Insert the Li-polymer battery to 2.0mm battery socket.
• Step2: Connect power adapter (support quick charge) to type_C interface by USB cable
• Step3: Check if the Quick charge indicator turns on.

Notices

• Module enter sleep mode when the working current is less than 40mA and stop to discharge.
• The Quick charge mode only works when you connect a power adapter that supports quick charge.
• To power Raspberry Pi, you can attach it on the GPIO or connect Type_A interface to Pi by USB cable.
• This module cannot work as UPS. It will turn off Raspberry Pi when low-voltage.
• The battery is about 4.2v when fully charged. Note that you should discharge the battery to 3.0, otherwise it is damaged.
• Please disconnect any devices when you replace battery.
• DO NOT change the battery provided with other battery without protective panel.
• Please check the poles of the battery interface carefully when you connect batteries.
