- 4.5V Max Load Output (from the bq25185 power path) – Ranges from 3.0V (low battery) to 4.5V (USB/DC/Solar active) at 1A max.
- 3.3V Regulated Output (via buck converter) – Delivers a stable 3.3V up to 1A, though it may dip to 3.0V when the battery is nearly empty.
- 4.5V Max Load Output – Never exceeds 4.5V, regardless of input voltage. High current draw may cause thermal throttling due to the onboard LDO regulator.
- 3.3V Regulated Output – A dedicated buck converter ensures efficient 3.3V output for low-power electronics.
- Orange – Charging
- Red – Fault
- Green – 3.3V Output Active
- Enable Pad – Allows disabling the 3.3V buck converter when not needed.
- Secondary Battery Monitoring Pads – Check battery voltage via breakout pads on the bottom.
- Mounting Holes – For easy installation in enclosures.
- Battery → BATT port
- Load Circuit → Use 4.5V Max or 3.3V Regulated output
