# 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.

=== 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.

The Lipo charger must be wired to the powerboost breakout as indicated in the assembly section.
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 and the final setup should look like the following:
Once soldered, plug a LiPo battery.

* PowerBoost LBO pin (Low Battery Output) is accessible on the breakout and may be useful to report battery state over the radio.
* The SparkFun Lipo charger/booster do no offer LBO pin (Low Battery Output).
{{ambox|text=WARNING: Do not connect LBO pin directly to a 3.3V GPIO!}}
{{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.
