Week 10 (Oct. 31, 2018): Battery Selection

 UPDATE: Calculations for the induction charging and battery are found in the Week 14 and Week 15 blog posts.

After finishing the last of the Presentation #2’s, time was provided to continue working on our projects. The first subject we wanted to address was to finalize the selection of our battery. So, we listed the pros and cons of the three main battery types: LiPo (Lithium-Polymer), NiMH (Nickel-Metal-Hydride), and Li-ion (Lithium-ion).

We eventually decided that we will be using LiPo batteries, like last year’s team, since they are more efficient and have a high energy density, along with their other benefits that outweigh their disadvantages and dominate the other battery types. Also, the fact that mini-LiPo chargers exist, such as the one below from Adafruit, will make charging more robust due to its compact design.

7.4, 2600mAh LiPo battery used last year:

  1. Small Scale Controls Team,

    I see how your induction charging method is planned to be used, but where are the calculations as the title of your post mentions?

    Where is any of your code that you've completed?

    Where is any of your rapid prototyping that you've completed?
