Guppy Bluetooth® Remaining Battery Capacity Estimate

The Guppy Bluetooth® will report battery voltage as part of its payload. 

This can be used to make some rough estimates of the remaining battery capacity - based on knowledge of LiFeSO2 battery chemistry. 

Voltage Range

Capacity Estimate

3.20 – 3.5 V

40% + remaining

3.10 – 3.20 V

25 – 40 % remaining

3.00 – 3.10 V

10 – 25% remaining

2.80 – 3.00 V

0 – 10% remaining

Note:

  • These groups do not imply a linear relationship in each range. The voltage should simply describe the 4 groups.
  • More accurate estimations are not possible at this stage because of the battery chemistry.
