FPV BATTERY → Type-C, Voltmeter + Checker (QC3.0 / PD3.1)

The Cheker Adapter-Converter is a device designed to transform FPV battery voltage into stabilized USB power. Equipped with a professional voltage tester and an audible alarm, it is perfectly suited for autonomous operation in field and combat environments.

• Input: XT60-M and balance connector (Voltage range: 8–30V).

• Output: USB-C (Supports PD3.1, QC3.0, PPS, AFC, FCP).

• Power: Up to 65W (Peak/short-term).

• Key Feature: Integrated tester with LED display and buzzer (audible low-voltage warning).

• Applications: Powering Starlink Mini, charging smartphones, tactical radios, tablets, etc.

• Materials: Housing made of 3D-printed plastic (PETG, PLA, or impact-resistant ELASTAN).

• Protection: Equipped with protection against critical battery discharge.

!!! Set the alarm threshold using the button on the tester !!! Do not allow the battery to fully discharge!

Operating Instructions:

1. Connection: Connect the XT60 to the battery and the balance lead to the tester. Press the button on the tester to set the alarm threshold (3.5–3.6V per cell is recommended).

2. Charging: Connect your device to the USB-C port; the adapter will automatically negotiate the optimal fast-charging mode.

3. Usage Limits:

   • Do not exceed 30V input voltage.

   • Avoid usage in excessively humid environments.

   • Do not use to power devices that exceed 65W.
