ToolkitRC MC8 Multi-Functional 2–8S Battery Checker

The ToolkitRC MC8 is a pocket-sized, multi-role battery checker and diagnostic tool designed for FPV pilots and drone builders. Beyond basic cell balancing and voltage monitoring, this device doubles as a signal tester and a field power bank, making it an essential diagnostic tool for track days and remote bando sessions.

Key features

• Supports voltage reading and balance checking for 2-8S LiPo, LiHV, LiFe and Li-ion packs directly via the balance port.
• Integrated signal diagnostic tool reads and outputs PWM, PPM and SBUS protocols, ideal for testing servos and checking receiver links without a flight controller.
• The USB Type-C port delivers up to 20W of fast charging to top up phones, radio transmitters or action cameras using your flight packs; the USB Type-A port (5 V / 1 A) is used for firmware upgrades.
• Bright 2.0-inch colour IPS display navigated by a tactile metal scroll wheel for rapid menu access.
