Safety Instructions & Warnings

• The charging current is set to 2.3-3.2A and charge cut-off voltage is 4.23V. Before connecting your battery to the UPS board, Please carefully confirm the maximum charging current and voltage, exceeding the upper limit of the charging specification that the battery can withstand will not only cause adverse reactions, but may also cause irreversible damage.
• It is essential to read and understand these safety instructions and warnings before charging your batteries.
• Lithium Polymer and Li-ion batteries are volatile. Failure to read and follow the instructions below may result in fire, personal injury, and damage to property if charged or used improperly.
• Never make a wrong polarity connection when charging or discharging battery packs. Always double-check the polarity of the battery's connector to ensure that "+" is connected to "+" and "-" is connected to "-".
• Do not mix and use old batteries with new batteries, or batteries with different brand names.
• Lithium batteries have a limited cycle life. Please replace old batteries with new ones when they reach their service life or when they are two years old, whichever comes first.
• When charging the Battery Pack, please place the battery in a fireproof container. Do not leave the UPS shield on wood material or carpet unattended.
• Keep the UPS shield away from children to ensure their safety.
• Please watch Main Video and Tutorial Video regarding 18650 batteries at: https://www.staysafebattery.com/en/

FAQ

Q: Why does the message "This power supply is not capable of supplying 5A" appear??

X120X series UPS shield can provide enough 5A power supply capacity;

Please set as follows:

Open the Teminal window based on Raspberry Pi OS and execute the following command:

sudo rpi-eeprom-config -e

Add PSU_MAX_CURRENT=5000 at the end of the file that reads like this:

Press Ctrl-O, then enter, to write the change to the file.

Press Ctrl-X to exit nano (the editor).

Reboot your Raspberry Pi 5 to make the change take effect.

Note: If you are using other OS like Ubuntu, please flash Raspberry Pi OS first, and then re-flash other OS such as Ubuntu etc after completing the above settings.

Q: How to disable auto power on feature on X1200?

A: When you connect an external power supply, the UPS board will automatically power on the Pi 5 motherboard while it starts charging, this feature is called auto power on, considering that some customers need to disable this feature, so we have also disclosed the following solution to disable it: please use a soldering iron to remove the resistor indicated by the arrow in the illustration.

PS: We don't think you need to remove the resistor to disable 'AUTO ON' function. Since there is an onboard switch, if you don't want AUTO ON, just press the switch to completely cut off the power.

WARNING: Please consider the following risks before removing this resistor:

• Do not operate if you are not a professional user
• The removal operation may damage the MCU, so please be careful with the operation.
• Once you remove this resistor by yourself, you will lose the warranty of this product. We no longer offer any warranty for this product.
• Once you remove this resistor, you can only turn on the power output by pressing the on-board switch.

Q: Why does the UPS shield continue to output power when PI 5 is turned off via press the on-board button?

A: The UPS shield provides enhanced power management features that intelligently monitor the power status of the Raspberry Pi 5 and automatically cut off power when the Pi is powered off. This helps optimize battery life by entering an ultra-low standby power consumption mode. It ensures efficient operation and maximizes the lifespan of the UPS battery.

To get the above features, check that the following settings are complete

Q: What battery is recommended for this ups shield

A: Please use high quality batteries from Samsung 35E 18650 lithium battery, Panasonic NCR18650B, Toshiba, etc. Do not use the battery with built-in protection circuit because it will limit the discharge current.

For the X1203 shield:

If using a lithium battery, the required voltage is 3.7V;

if using a battery pack, please make sure it is a parallel battery pack.

There are 2 XH2.54-2P battery connectors on board, it is recommended to use the same type of battery.

Q: Run sudo i2cdetect -y 1, can't find I2C address 0x36?

A:

1. Make sure you enable i2c interface, refer to How to enable I2C

2. The UPS connects to the Pi GPIO via pogo pins, If the I2C address (0x36) is not detected, Please clear the leads of pin 3 and pin 5 on the GPIO header from the bottom of the Raspberry Pi PCB and install again, and also check if the pogo pin of ups shield is in close contact with the pad position of PI 5(you can adjust the [pogo pin] position).

There won't be any other problems, it's this poor contact that's causing it.

Q. How do you disable the X1202 auto-shutdown when you use it standalone (not installed on a RPi5)?

A:

Q. X1203 UPS voltage drops / low voltage warning appears?

A:

1.Powering the X1203 via Type C connector with / without the batteries，Pls check if you still have the issue.

2.Please clear the test pad on the Pi's PCB bottom which is used for connecting the X1203 for 5V power delivery.

I can confirm that it will work with a 12 volt outlet in a car. I am typing this comment on my RPI5 8GB with the X1203 while plugged into a 12 volt outlet (13.8 volts). I first tested this on my 12 volt power supply (13.8 volt) that I use to power my 2 meter ham radio. Work Well!

With the 6-20V input on the DC jack, is it safe to operate this directly from vehicle/car power or do you recommend using an external regulator in between? Thanks!

Hello，Sorry, we haven't tested it with the car and can't offer advice.

it is recommended to use a case to protect the board and battery if you use it in a car.

yes.

I want to adjust the voltage settings for the LED indicator lights so that they correspond to 25%, 50%, 75%, and 100% of the battery charge. Currently, even though the battery voltage is low, the battery indicator is incorrectly showing a higher charge level.

Hi,LED lights do not support software settings.There is a learning process for the IC to read the power level, please try to fully charge and then discharge it a few times and it will remember the process.

UPS X1203 works really well. All I need is for the batteries to start charging when the power is connected. Turn on/off X1203 only when the button is pressed. For example: your laptop doesn't turn on automatically when you decide to charge its battery.

And I agree that the warranty will be cancelled (as you wrote).

How to disable auto power on feature on X1203?

On the X1200 board, the arrow points to a different resistor than on the X1201 and X1202 boards. Which resistor should be removed on the X1203 board?

Since there is an onboard switch, you don't have to disable the AUTO ON function. If you don't want AUTO ON, just press the switch to completely cut off the power.

I really want to delete the description of how to disable the AUTO ON function of the other 3 products.

Is the amperage of the 5V out xh 2.54 connectors the same 5A? Also, is this 5A only when connected to power? If it is not 5A when only running off of battery, how many amps will it produce from the 5V out connectors on just battery?

The X1203 can provide a maximum output current of 5A. Please note that it has this capability, and the actual output current depends on your load.

I recently purchased two X1203 boards and one X1202 board for testing purposes. I'm encountering an issue with the X1203 boards - neither of them is being recognized via I2C. However, the X1202 board I bought is working fine and is detected without any problems.

I've double-checked the connections and tried cleaning the GPIO pins, but the X1203 boards still aren't showing up when I run i2cdetect.

Is it possible to modify the maximum charge voltage? For safety and longevity of the cells I would like them charged no higher than 3.75v - Is it possible for the user to make this change?

Is it also possible to modify the minimum voltage before automatic shutdown is triggered?

Is it possible to modify the maximum charge current?

Control over all of these settings would not only allow for safer operation and longer battery lifespan but would also allow for the use of LiFePO4 cells which are considerably safer and a better fit for a UPS application.

The spec sheet for the recommended Panasonic batteries NCR18650B says max charging voltage is 4.20v, however the specs here state that the Terminal Battery Voltage = 4.23V. Shouldn't the 1203 cut off charging at 4.20V?
