Cellmeter 8 Multi-Functional Digital Power Servo Tester

A workbench building and maintaining RC and drone gear tends to accumulate a separate tool for every diagnostic job, one tester for servo sweep, another for ESC throttle response, another still for checking a LiPo pack's individual cell voltages. The Cellmeter 8 folds all three of those jobs into one handheld unit, letting a builder run a servo through its range, confirm an ESC is responding consistently, and check a battery's cell balance without switching between separate devices for each check.
