Overview
Note: Sold out and no longer in production. Please refer to X728
- The X750 is a multi-functional expansion board for all current models of the Raspberry Pi using a 40 pin header. It provides intelligent and safe power management, safe shutdown, full power off through software and an advanced uninterruptible power supply.
- The X750 reserves the 40-pin header that can be stacked with other Raspberry Pi accessory boards for enhanced applications, and it's the high-end product of the Geekworm UPS family.
- Important Note: The X750-A2 must be use with X750 18650 UPS HAT Shield, it is no use if you just purchase the X750-A2 board.
SAFETY INSTRUCTIONS AND WARNINGS
- You must read these safety instructions and warnings before charging your batteries.
- Lithium Polymer and Li-ion batteries are volatile. Failure to read and follow the below instructions may result in fire, personal injury and damage to property if charged or used improperly.
- Never make wrong polarity connection when charging and discharging battery packs. Always double check polarity of battery's connector to make sure "+" to "+" and "-" to "-".
- Do not mix and use old batteries and new batteries, or batteries with different brand names.
- Lithium batteries has it's cycle life, please replace old battery with new one when it reaches it's service life or when it is two year old, whichever comes first.
- When charging Battery Pack, please put battery in a fire proof container. Please don't leave the X700 on the wood material or carpet and unattended.
- Must keep the X700 away from children.

Customers often ask if we support automatic and safe shutdown at low battery capacity? Our suggestion is: You can refer to the A file and the B file to program this idea yourself: The idea is to read the current voltage or battery capacity cyclically, and then judge the program to execute the automatic shutdown command when it is low or low voltage, of course This low battery or low voltage value is an empirical value, and you can specify it yourself in the program.

FAQ
Q: 1. Will the X750-A2 stackable? Can we double or triple or more X750-A2 to hold 12/16 batteries?
A: No limit to X750-A2,you can stack mutiple X750-A2 to hold and add more batteries. But please note that the charging current is only about 2.5A, so the charging speed will be become slow if you stack mutiple X750-A2.
Q: 2. Will X750 have an auto shutdown if the battery is low?
A: Sorry no, the X750 does not support an auto shutdown if the battery is low.
Q: 3. How many Amps can be used on each of the various XH2.54 5V Output connectors??
A: All 5v output connectors are connected together and they can deliver total 8A output.
Q: 4. What is the pinout for the PWR Switch?
A: Please refer to here: PH2.0 Conector Specification
Q: 5. Does the X725/X750 support to use with X735 together?
A: Sorry, no, the X725/X750 does not support to use with X735 power management board, please do not use them togehter.
Q: 6. Can X750 provide enough power supply when PI 4 is overclocked to 2.0ghz?
A: No problem, X750 can output current up to 8A
Q: 7.How to remove/unload the X750 script from your Pi?
A: Open the /etc/rc.local file (sudo nano /etc/rc.local or vim /etc/rc.local to open the /etc/rc.local file;), and seach x750, then comment out that line (add # on the begin of that line);
Q: 8.Does the X725/X750/X705 support power failure detection?
A: No, the X725/X750/X705 dose not support power failure detection.
Q: 9.Does the X750 support to use with X835?
A: No,not support. They requires different power supply voltage, can't use togehter.
Q: 10.X750 is not compatible with adafruit 3.5" touchscreen problem
A: Please refer to https://geekworm.com/community/forum/topic/12496/x750-pinout
Q: 11.Why do not use 18650 battery with built-in protection circuit for X750?
A: The X750 has an onboard fuse, if the battery can be installed, you can directly use the battery with protection circuit, but the output power may be affected.
