Battery Monitoring

OrniFlight monitors main battery voltage via the ADC (Analog-to-Digital Converter). This enables low-battery warnings through buzzer, status LED, and LED strip patterns.

Features

• Auto-detection of cell count on connect (based on min/max cell voltages)
• Low battery warning with configurable thresholds
• Current sensing for mAh consumption (if supported by FC)
• Voltage displayed in OSD and transmitted via telemetry

Supported Targets

All supported flight controllers (OMNIBUSF4, TINYFISH) include VBAT monitoring via voltage divider.

Connections

ALWAYS CHECK POLARITY. Measure expected voltages before connecting. Incorrect voltage or reversed polarity will destroy your flight controller.

OMNIBUSF4

Connect main battery to VBAT pad. The onboard voltage divider handles up to 6S directly.

TINYFISH

VBAT is routed through the board’s power input — no separate connection needed.

CLI Settings

set vbat_min_cell_voltage = 330 # Minimum per-cell voltage (3.3V) set vbat_max_cell_voltage = 430 # Maximum per-cell voltage (4.3V) set vbat_warning_cell_voltage = 350 # Warning threshold (3.5V) set battery_meter_type = ADC set current_meter_type = ADC # If current sensor available

Safety

LiPo batteries should never be discharged below 3.5V per cell under load. OrniFlight’s configurable thresholds help ensure safe operation and battery longevity.
