UPS HAT (B) For Raspberry Pi, 5V Uninterruptible Power Supply, 5A High Current, Pogo Pins Connector Specifications OUTPUT VOLTAGE: 5V CHARGER: 8.4V 2A CONTROL BUS: I2C DIMENSIONS: 56 × 85mm BATTERY SUPPORT: 2x 18650 Li batteries (NOT included) MOUNTING HOLE SIZE: 3.0mm 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, should always 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.

• Designed for Raspberry Pi series, compatible with Raspberry Pi 3 / 3B+ / 4B, etc.
• I2C bus communication, monitoring the batteries voltage, current, power, and remaining capacity in real time
• Multi battery protection circuits: over charge/discharge protection, over current protection, short circuit protection, and reverse protection, along with the equalizing charge feature, more safe and stable
• Onboard 5V regulator, up to 5A continuous output current, more sufficient power source for Raspberry Pi
• 5V USB output, convenient for powering other boards, batteries warning indicators, easy to check if the battery is connected correctly
