Hello Nordic Team,
I am currently working with the nPM1300 EK together with the nRF54L15 platform and a custom 40 mAh Li-Po battery.
I am facing an issue while configuring battery charging and discharging parameters in nPM PowerUP v2.2.4. The tool currently provides a minimum battery capacity option of 400 mAh, and I am unable to configure or generate settings for a 40 mAh battery.
I would appreciate your guidance on the following points:
- How to create a valid battery profile .inc file for a 40 mAh Li-Po battery.
- Recommended charger configuration values for:
- Charge current
- Termination current
- Cutoff voltage
- Whether it is possible to use the fuel gauge functionality without the dedicated nPM Fuel Gauge Board.
Recommended approach for performing charge/discharge testing and SOC estimation using only:- nPM1300 EK
- nRF54L15
- 40 mAh battery
- Any available examples or documentation for low-capacity batteries (<100 mAh) with nPM1300.
Current setup:
- nPM1300 EK
- nRF54L15
- 40 mAh Li-Po battery
- NCS SDK v3.2.0
- nPM PowerUP v2.2.4
At the moment, I do not have the nPM Fuel Gauge Board available, so I would also like to understand the limitations and supported workflow without it.
Thank you for your support.
