Part Number: BOOSTXL-BATPAKMKII
I got a new BOOSTXL-BAKPAKMKII and was using it to power up my MSP430F5529. The system was working well and at some point it stopped. First, I thought that the battery was discharged completely. So, I plugged the fuel tank to desktop computer via USB cable in order to charge it. The "charge active" LED was on when I first plugged it. I left it for almost 48 hours, not on purpose. However, when I came back the LED was off. I tried it but the output is approx. 2 Volts. I plugged it again but this time the LED stayed OFF. I checked the connection and then I plugged it carefully and I saw that the LED is blinks for like tenth of a second and then goes OFF. I left it in charge for a while.
Then I used a multimeter to measure the output voltages from both 3.3V and 5V pins. They both show around 1.5Volts. Interestingly both output decreases in a stable manner as they were discharging over a capacitor. More surprisingly even though I changed the switch from "Connect" to "Disconnect", I was be able to see the same output values around 1 Volt and the discharging patter. Now both output show 0 Volts, as they were discharged.
Could you please help me about this problem?

Thank you very much for the answer. I left my office and could not provide you the exact jumper settings. The toggle switch was "ON", that's for sure. I used dip connected the BATPAK over MSP430F5529. It worked for couple of weeks and then stopped.
Before I saw your message I have tried these things:
1. I had a BOOSTXL-BATTPACK as well. When I connected the LİPO of BATPAKMKII to BATTPACK module and try to charge, the "charging" LED was ON.
2. I tried to charge the LİPO of BATTPACK from BATPAKMKII module, the "charge active" LED was ON.
3. I powered MSP430F5529 with BATTPACK, everything was fine.
4. I changed the LİPO's; that is I disassembled the LİPO from BATTPACK and connected it to BATPAKMKII. Everything worked fine. After half an hour I realized that the the system was off. I checked and found that the output of the LİPO was zero again. I tried to charge, no luck. So, it happened again. "Charge active" LED blinks for a very briefly and then goes off. To sum, the same thing happened when I use the old LİPO from BATTPACK.
I am going to post the whole connections tomorrow.
As I said the toggle was "CONNECT". The BATPAKMKII was plugged on MSP-EXP430F5529LP launchpad.
We are using 5V, GND, P3.3(RX), P3.4(TX) pins for a bluetooth communication.

Dear M, Please make sure that all MSP-EXP430F5529LP eZ-FET lite jumpers are unpopulated when the BOOSTXL-BATPAKMKII is connected. I am trying to loop in someone who has more expertise with this battery BoosterPack to help answer your questions. Once more, please send all jumper configurations. Regards, Ryan
I am using only the pins and connections I wrote above. Nothing is connected to ex-FET lite jumpers. Moreover we did not change a single thing in the launchpad. But if you are asking something apart from these by saying "jumper configurations", I did not get it. I am sorry. Could you please provide me some more details?
Btw, I forgot to mention that I always disassemble the (both) BOOSTERPACK from MSP-EXP430F5529LP and try to charge but it does not work.
Hi Murat, Were you able to find any resolution to this issue? Do you have any updates to provide? I will mark this post as closed, it will open back up once responded to. Regards, Ryan
