Lithium battery setup: A first plan

We are pretty sure we want lithium batteries (LiFePO4) in Chip-Chip. Mostly because we don’t have a lot of space, and as lithiums can be discharged to about 20%, they will give us more power in less space and with a lot less weight.

But lithiums are fairly sensitive, so it is necessary to carefully think the electrical system through before installing them. Our first thought was to  buy a “plug-and-play ” lithium setup, which includes a BMS system. This seems like the easiest solution, but the more we learned about lithiums, the more uncomfortable it made us not knowing the details of the system. Continue reading
