Pi-UpTime UPS 2.0
UPS for Raspberry Pi-4 using Li-
Ion or Li-Phosphate batteries
Pi-UpTime UPS 2.0 is a new
and improved version of the
Pi-UpTime UPS. Pi-UpTime
UPS 2.0 is designed to work
with the Pi-4 or other SBC’s,
such as Odroid, Asus, Arduino
etc. Power is supplied via the
40-pin header or via the
micro-USB out port. Powering
the Pi and charging the
battery is done on the Pi-
UpTime UPS 2.0 via a USB-C
or a micro-USB connector.
Only one connector can be
used at any time for power.
The micro-USB connector is provided for backward compatibility. The Pi-UpTime 2.0
has the same dimensions as a Pi-4 (or Pi2, Pi3, etc.) and can be mounted securely on
a Raspberry Pi using 20 mm spacers for a compact, mechanically secure connection.
An on-board 12-bit ADC monitors Vin, Vout and battery Voltage for accurate
information on operating conditions. Temperature sensor below the battery provides
accurate battery temperature information. Battery charging takes place between 0oC
and 50oC. No GPIO connections or GPIO monitoring is needed. ADC provides
information via the I2C. Up to three different I2C address can be selected via jumpers
J11, J12 to avoid conflict with other I2C devices. Sample python code is provided for
monitoring system parameters and shutdown the system when power fails, and
battery is low. Sample code can be downloaded from www.alchemy-power.com
External connections, via solder points, are available for I2C, Vin, Battery and Vout.
The connections can be accessed via 2.54mm (100 mil) terminal blocks or by direct
soldering. Terminal blocks are not included. External sensors or external controllers
such as an Arduino controllers or other embedded micro-controllers can tie into the
I2C connection.
Key Features:
•Provides UPS

These connection points can be used for an external battery
1
, external Vin or external Vout. Max current
for the overall system is 2.5A. External battery can be Li-Polymer, Li-Ion or Li-PO4. Please use Jumper J4
to select chemistry. Li-Ion and Li-Polymer share the same jumper setting.
Current for the UPS is limited to 2.5A via a current limit resistor. Since the USB connector provides
power for charging the battery and is also providing power to devices connected via Pi-UpTime UPS 2.0,
a 3.5A power supply is recommended. We also recommend using good quality USB cables to minimize
power loss via USB cables. Using the USB-C connector is recommended for Power In.
3.3V UPS power is available via terminal block J2. Maximum of 0.7 Amps can be drawn from this
connection. This is useful to provide power to external sensors, IoT and other electronic devices.
Batteries or spacers are not included.
Key Features
•Provides UPS using one or two rechargeable 18650 Lithium batteries in battery holder or connecting
an external battery. Batteries are not included. An external battery can be used instead of onboard
battery connectors. Unit is agnostic to battery capacity. Charge and UPS run-time will vary according
to battery capacity.
•Choice of Li-Ion, Li-Polymer or Lithium-Phosphate batteries. Jumper selectable (Li-Ion / Li-PO4) battery
chemistry via jumper J4. Both batteries in the battery holder must be identical. Battery chemistry
selection is done via J4. Default selection is for Li-Ion. Li-Polymer batteries can be used with an
external connector. For Lithium Polymer batteries, use the Li-Ion battery setting on jumper J4.
•Install one or two 18650 batteries (not included). Please ensure the batteries are installed with the
proper polarity. Reversing the polarity will damage the electronics.
•Includes full Battery Management System (BMS). Charges the battery when power is available using
CC-CV charging methods. Depleted batteries are charged initially at a low current, allowing batteries
to recover.
•On board ADC allows Vin, Vout, Battery V and temperature monitoring via I2C. Sample Python code
can be downloaded for use. The sample code can be modified to adapt to your needs. NO GPIOs are
used. Only an I2C bus is shared with other I2C peripherals. Valid I2C addresses are 0x48, 0x49, 0x4B.
Default address is 0x49.
•System turns off all power and shuts down when batteries fall below 2.6V, protecting the batteries.
•Power reset is done by pulling off the Power on/off shunt on Jumper J3. By connection an on/off
switch to jumper J3, power can be turned on or off as needed. Switch can be connected via a 2.54mm
cable header. This cable can be purchased from several places. Such a cable is available, for example,
on Amazon from Alchemy Power, product id B07FXXDN2M.
•Using spacers, Pi-UpTime-UPS can mount securely on Raspberry Pi-4, Pi 3B+, 3, Model A etc.
•Maximum battery charge current is limited to 1A. Battery charge time will vary based on battery
capacity and battery charge level.
•Several safety features are built-in on Pi-UpTime UPS 2.0.
oIncludes Battery Management System (BMS) which maintains CC-CV charging and
maintains the charge level for Li-Ion or Li-PO4 batteries, once the batteries are charged.

All information subject to change without notice.
oA temperature sensor senses ambient temperature around the batteries and shuts down
charging when it gets hot. Operating conditions for battery charging are 0oC to 50oC.
oAn initial slow charge for depleted batteries is provided to allow batteries heavily drained
to recover gracefully.
oA PTC fuse is provided for second battery to prevent battery current loops. Battery current
loops are created when a charged battery and a discharged battery is connected.
oCharging current is limited to 1.2A. This reduces heat and improves operating conditions.
oTotal current is limited to 2.5A, thus protecting the overall system.
•All LED’s can be turned off. This is done by removing shunt on J5.
•Power to the Pi is provided via the 2x20 pin header, pins 2,4.
•UPS out –regulated 5 V and 3.3V. A maximum of 2.5 Amps for overall UPS system. 0.7Amps for 3.3V
UPS power. Please make sure thebattery can sustain 2.5 Amps or more as output or discharge current.
Many Li-Polymer batteries cannot sustain such current load and may discharge rapidly.
•LEDs indicators:
oGreen –Battery is charging. LED is on when the battery is charging. Off when battery is
charged. LED also indicates Power via USB is on.
oBlue –UPS is on and operational.
oRed –Fault. Attention should be provided to ensure the system shuts down properly or
provide an alternate power source of power.
oYellow –Power supply input V is below 4.8V and battery may not charge. At this Voltage the
Raspbian OS also shows a lightining bolt as well.
•Sample Python code to monitor system is available. Download from Alchemy Power Inc. website or
at www.alchemypower.com/downloads .
•Output Voltage –UPS generates regulated 5.0V (±2% across full load range). When the Power is
available (via the Power on port), the power is passed through to the output via a very low loss ideal
diode.
•Power In can be via the USB-C port (recommended) OR via the micro-USB port. Micro-USB port power
adapters usually do not provide enough power (amps) and drop the Voltage when there is a heavy
load demanded. This situation will cause the Yellow LED to be on and may also display the lightining
bolt on Raspbian.
Please visit www.alchemypower.com/products for additional information and sample python code.
Recommended installation steps
1. Remove Jumper J3 to turn off all power to the Pi and external power sources (USB-out, 3.3V).
a. Insert an on/off switch if desired at Jumper J3. Ensure the switch is in the off position.
2. Select the battery chemistry based on battery you are planning to use on jumper J4.
a. For Li-Polymer battery, use the same setting as Li-Ion.
b. For a Li-Phosphate battery, switch the jumper to the Li-PO4 setting.
3. Insert the battery in the battery holders. Make sure you follow the proper polarity. Improper
battery insertion can damage the electronics.
