=== Pico, SparkFun Lipo Charger/Booster and Cansat Kit ===
The {{pl|2271|Kit Cansat with Pico}} does have a footprint to receive an Adafruit PowerBoost 500 charger. This can also be used with a {{pl|2508|SparkFun Lipo Booster/Charger}}.
The Lipo charger must be wired to the powerboost breakout as indicated in the assembly section.

Once soldered, plug a LiPo battery and the final setup should look like the following:

{{ambox-stop|text=Some third-party LiPo cells have JST connectors wired opposite from the standard! Connecting these to the PowerBoost will damage your PowerBoost. Double check the polarity before connecting.}}
{{Underline|'''What are the features:'''}}
* Plug the USB on the Pico to refill the LiPo.
* Unplug the USB to make the LiPo powering the CanSat.
* The PWR_OFF connector (near the border of the board) can be fitted with a switch. Close the switch (so PWR_OFF tied to the ground) to deactivates/shutdown the PowerBoost.
* PowerBoost status LEDs are visible under the CanSat (see next section for description).
* PowerBoost LBO pin (Low Battery Output) is accessible on the breakout and may be useful to report battery state over the radio.
{{ambox|text=WARNING: Do not connect LBO pin directly to a 3.3V GPIO!}}
{{underline|About LBO pin}}: the LBO Pin is pulled high to '''BAT''' voltage (so 4.2V when battery is fully charged) in normal operation. When the battery voltage drops under 3.2VDC then the LBO pin is tied to the ground.
