BOOSTXL-BATPAKMKII: Problem on charging Fuel Tank MKII Battery BoosterPack

Part Number: BOOSTXL-BATPAKMKII

Dear TI Engineers,

I have bought a Fuel Tank MKII Battery BoosterPack:

https://www.ti.com/tool/BOOSTXL-BATPAKMKII

I tested it with the example given in MSP432P401R Launchpad.  It worked.  I could see its being charged from the serial terminal as described in its user guide.

When it was fully charged, I then used it together with another Launchpad, it was still working.  I confirmed that it supplied power to that launchpad.

  1. When it was completely discharged, I put it together with the MSP432P401R Launchpad again.  I charged it for 10 hours and I could not see any charging information from the serial terminal.  The charging failed.  What is wrong with this step?
  2. What is the simplest way to recharge Fuel Tank MKII Battery BoosterPack without using an extra launchpad?
