I was planning to buy the original Fuel Tank Booster Pack, but for whatever reason it became not available to purchase. Several months pass by and still it is still not available to purchase. I felt dissapointed, with the thought of not being able buy the original Fuel Tank Booster Pack and be able to use it for future TI Launchpad based projects, since the the original Fuel Tank Booster Pack have been been featured at Project blogs and youtube videos. However good news came from a TI Engineer last July 2016 who announced that TI would release 2 new Booster Packs, and one of the Booster Pack is the new Fuel Tank MKII Battery Booster Pack.
The Fuel Tank MKII Battery Booster Pack is pin compatible with the Tiva Connected Launchpad Booster Pack 1 and Booster Pack 2 connector. For this simple project, I will connect the Fuel Tank MKII Battery Booster Pack to Booster Pack 2 connector of my Tiva Connected Launchpad. Tiva Connected Launchpad I2C2 will be used to communicate with the Fuel Tank MKII Battery Booster Pack.
One noticeable difference of Fuel Tank MKII Battery Booster Pack from the original Booster Pack is the addition of a mechanical Switch S1, that enables you to fully disconnect the battery from the onboard circuitry.
- 3.7 Volts 1200-mAh lithium polymer battery.
- Onboard bq27441 fuel (gas) gauge.
- Onboard bq24250 lithium polymer charger.
- USB charging with indicator LED.
- Works with TI Launchpad development kits.
