# Tied the '''Lipo Charger/Booster EN pin''' to the ground : this disable the the Power/Booster which stops to power up the Pico. The best approach.

=== Pico, PowerBoost and Cansat Kit ===
=== With Adafruit PowerBoost ===
The {{pl|2271|Kit Cansat with Pico}} does have a footprint to receive an Adafruit PowerBoost 500 charger. This works exactly as described above but with all the wiring already done on the board.

{{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.

=== With SparkFun Lipo Charger/Booster ===
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 Lipo Charger/Booster breakout as indicated in the assembly section the "[[ENG-CANSAT-PICO-ASSEMBLY|Assembling section]]".
We do recommend to wire the Lipo Charger/booster UNDER the base plate (to preserve access to the Pico signals on the top).

Once soldered, plug a LiPo battery.
{{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 Lipo Charger/Booster.
* The status LEDs are visible under the CanSat (see next section for description).
* The SparkFun Lipo charger/booster do no offer LBO pin (Low Battery Output).
{{underline|'''Charger/Booster Status LEDs:'''}}
The onboard <font color="blue">'''Blue LED'''</font> indicates the charge status of the Lipo battery.
* '''No battery''': LED floating (should be OFF but may flicker).
* '''Shutdown''': LED floating (should be OFF but may flicker).
* '''Charging''': <font color="blue">'''LED ON'''</font>.
* '''Fully Charged''': LED off.
