Hi all,

I was checking battery level measurment and found this levels:

3.00, // 00%
3.78, // 10%
3.83, // 20%
3.87, // 30%
3.89, // 40%
3.92, // 50%
3.96, // 60%
4.00, // 70%
4.04, // 80%
4.10 // 90%

I see a leap between 3.0v and 3.78v, and a non costant increase between other values. Are this experimental values or how did you found this levels? Also, this leap between 3.00v and 3.78v is still usable or should I cut off power below 3.78v?

Thank you!

Lithium Ion batteries are nonlinear. Sounds like the percentages were adjusted to account for this nonlinearity to present a linear domain (time?)

Here's a randomly chosen graph from the internet to illustrate:

But this are Li-Po batteries, can be applied same graph?

I picked a random chart. Here's a similar graph for lipo
