How to monitor Bluetooth batteries on iPhone and iPad

Before you start

Confirm the battery brand, exact model, or internal BMS family. Two batteries sold under the same brand can use different internal Bluetooth hardware, and experimental compatibility can vary by model and firmware.

• Wake the battery and make sure its Bluetooth function is active.
• Keep the iPhone or iPad near the battery during initial discovery.
• Fully close the manufacturer's monitoring app on nearby phones and tablets.
• Allow Bluetooth access when iOS or iPadOS requests it.

Connect and verify a system

1. Open BMS Monitoring Suite. Use Demo Mode first if you want to learn the interface without connecting hardware.
2. Start system setup. Choose the battery or power-system family that matches the actual device, not merely a similar brand name.
3. Scan inside the app. Do not pair the battery from the Bluetooth page in the device Settings app unless its manufacturer specifically requires that workflow.
4. Verify fresh telemetry. Confirm that values such as state of charge and voltage are plausible and updating before saving the system.
5. Describe the layout. If the saved system contains multiple batteries, identify its series or parallel arrangement so the dashboard can present meaningful aggregate readings.

What you may see

Available readings depend on the hardware. Supported systems can report state of charge, voltage, current, power, temperature, remaining capacity, health, cycle count, signal strength, cell voltages, or channel-level power flow. A missing value does not necessarily mean the connection failed; the device may not report that field.
