RC CellMeter 8 Battery Checker

The RC CellMeter 8 is a handheld voltmeter built for hobbyists who fly or drive radio-controlled models. It reads individual cell voltages for lithium packs up to eight cells and nickel packs up to eight cells. The backlit LCD shows total voltage, lowest cell, highest cell and the gap between them. A servo test port lets you verify standard or narrow servos on the bench.

Thermals Noise and Power Draw

The unit draws its operating power from the balance plug of the battery under test so no separate supply is needed. Current draw is low enough that the tester does not warm up during normal checks. There are no fans or moving parts so operation is completely silent. The balance current is rated at 1A for the internal measurement circuit.

Upgrade From Basic Checkers

This replaces simple LED indicators or single-cell meters that only show total pack voltage. The jump is worth it when you need per-cell data to spot a weak cell before parallel charging or to confirm balance after a charge cycle. It also covers nickel chemistries that many lithium-only tools ignore. Builders who need logging or internal resistance data will need a more advanced analyser.

Questions about this item

How do I connect the balance plug to the CellMeter 8 for an 8S LiPo pack?

Align the balance connector with the port marked for up to 8 cells, ensuring the negative lead matches the ground pin; the LCD backlight then shows individual cell voltages, total voltage, lowest cell, highest cell and the voltage gap.

What ongoing check does the CellMeter 8 require to stay accurate?

Verify the 0.001 V test precision periodically by measuring a known reference cell; no internal calibration routine exists, so external comparison is the only maintenance step.

At what pulse width does the servo tester stop responding?

The servo test range covers 1000–2000 µs or 500–2500 µs; signals outside those limits will not drive the servo.
