A2212 930KV Brushless Outrunner Motor - Pre-Soldered 3.5mm Banana Plugs with X-Mount & Prop Adapter βΉ499.00 Quick Introduction: Eliminate the guesswork from your RC workbench with the CellMeter 8, the upgraded successor to the popular CellMeter 7. This multi-functional diagnostic tool combines a high-precision Battery Voltage Checker with a fully-featured Digital Servo Tester in one compact unit. Whether you need to verify if a LiPo pack is safe to fly, balance-discharge a battery for storage, or centre a servo before installation, the CellMeter 8 is the "Swiss Army Knife" of RC electronics diagnostics.
Detailed Specifications:
Supported Battery Types: LiPo, LiFe, Li-Ion (2S-8S Balance Port), NiCd, NiMH (4S-8S Discharge Port).
Measurement Precision: 0.001V (Voltage), 1% (Capacity).
Servo Test Modes: Manual (Knob), Neutral (1500Β΅s Centre), Auto (Window Wiper Sweep).
Servo Output Frequency: 50Hz, 60Hz, 100Hz, 125Hz, 200Hz, 250Hz, 300Hz (Selectable).
Discharge Current: 90mA x 8 Cells (Max @ 4.2V) β Note: For slow balancing, not high-amp discharge.
Display: 2.1" Backlit LCD (Blue/White) for night visibility.
Dimensions/Weight: 84mm x 52mm x 15mm / 48g.
Quality Advantage & Differentiation: Why upgrade to the CellMeter 8? Unlike the older CellMeter 7, this V2.0 unit features a Backlit LCD Screen, making it readable in direct sunlight or dark workshop corners. The standout feature, however, is the Integrated Servo Tester. Instead of carrying a separate PWM generator, this unit allows you to plug in servos or ESCs directly to test the range of motion, detect gear binding, or spin up brushless motors for direction checks without needing a radio receiver.
Key Applications & Usage
Pre-Flight Safety Check: Instantly view Total Voltage, Individual Cell Voltages, and the "Gap" (difference between highest and lowest cell) to prevent flying with unbalanced packs.
Servo Centring: Set the device to "Neutral" mode to send a perfect 1500Β΅s signal, ensuring your servo arms are installed at exactly 90 degrees.
ESC Calibration: Use the "Manual" knob mode to simulate throttle stick movement (0-100%) for calibrating Electronic Speed Controllers (ESCs) safely on the bench.
What's Included & Required
Included: 1x CellMeter 8 Multi-functional Tester, 1x User Manual.
Required: No internal battery required; unit is powered by the battery pack being connected (for 2S-8S). Note: Testing 1S batteries or standalone servos requires an external 5V power source connected to the NiCd/Servo port.

β οΈ CRITICAL SAFETY WARNING:
Servo Port Voltage: The 3-pin servo port (Left Side) is rated for 5V-6V MAX. DO NOT plug a 2S (7.4V) or 3S (11.1V) battery directly into this port, or you will instantly burn out the servo testing circuit.
Balance Port: Always align the Black (Negative) wire of your balance plug with the pin labelled (-) or Ground at the bottom of the port.
Pinout Reference:
Left Side (Servo/NiCd Port):
Top Pin (S): Signal (Pulse Output/Input)
Middle Pin (+): Positive (VCC 5V-6V)
Bottom Pin (-): Negative (Ground)
Right Side (Balance Port):
Bottom Pin: Ground (-)
Pins Moving Up: Cell 1, Cell 2, Cell 3... up to Cell 8.
Troubleshooting: Screen won't turn on with a 1S battery? The device requires at least ~6V to operate. To test a 1S battery, you must provide auxiliary 5V power to the "NiCd/MH" port first to wake up the screen.
