Raspberry Pi 5/4B/3B+/3B X729 18650 UPS (Max 5.1V 6A) with Wide 6-24V Input|Auto Power On|Safe Shutdown

Note:

1. The script must be installed first for the product to work properly!!!
2. The Raspberry Pi, 18650 battery, metal power switch, oled is not included in the packing list.

Overview
The X729 is an ultra-compact advanced uninterruptible power supply expansion board for all current models of the Raspberry Pi using a 40 pin header.

It provides Max. 5.1V 6000mA Power Backup for even the most demanding Raspberry Pi set ups, intelligent and safe power management, safe shutdown, auto power-on, battery reverse polarity protection circuit, AC Power Loss Detection, real- time clock(RTC), OLED display, battery capacity reading, low battery automatic shutdown, buzzer alarm, PWM Fan and Wide Voltage 6-24V Input.

The X729 reserves the 40-pin header that can be stacked with other Raspberry Pi accessory boards for enhanced applications. The X729 can also be used with the X825 (2.5" HDD/SSD Shield) and X857 / X862 (MSATA/M.2 NGFF SSD shield) for safe data backup.

• Jumper setting to enable Auto power on when power applied or restored
• Automatic safe shutdown when battery low (voltage programmable)
• Onboard buzzer alarm for power loss and low battery
• Integrated Hardware Real Time Clock (RTC) with Battery BackUp, uses the most common DS1307 RTC real time clock
• Onboard PWM cooling fan with air flow up to 6.01CFM and maximum speed of 5000 RPM, programmable temperature and fan speed
• Powers the Raspberry Pi via the 40pin header no additional cabling required, reserved 40pin stackable header for extension boards
• With 1x4 Pin header and screw holes for OLED display(click to order if you need one)

How to Power & Specifications

• Power via DC 5521 power jack of X729: 6-24Vdc, ≥3A; (The power output needs to have surge protection and overvoltage protection, otherwise it will easily burn the DC chip of X729.)
• Power input: 6-24Vdc, ≥3A
• UPS output : 5.1V ±5% Max 6A
• UPS charging current: 2.3~3.2A
• Terminal Battery Voltage : 4.24V
• Battery Recharge Threshold : 4.1V

Warning about power supply:

1. Don't use that adjustable voltage power supply.
2. Don't use the same power supply used on LED strips

The above two are absolute garbage power supply, can not be used!!!
