Five-piece 1-8S LiPo voltage checker

This pack supplies five identical 2-in-1 testers that measure individual cell voltage, total pack voltage, lowest cell voltage and remaining capacity for 1 to 8-series lithium-polymer, lithium-ion, lithium-manganese and lithium-iron packs. Each unit fits in a pocket at 4 by 2.5 by 1.1 centimetres and weighs 45 grams. Hobby pilots and builders who need a quick health read-out before every flight will find the quantity convenient for multiple models or field spares.

0.01-volt resolution with 0.5-to-36-volt total range

The display shows cell voltages from 0.5 to 4.5 volts and totals from 0.5 to 36 volts, while the 1S test mode covers 3.7 to 30 volts. A single top button steps the low-voltage alarm threshold between off, 2.7 and 3.8 volts, defaulting to 3.3 volts, and the setting is saved after power removal. Reverse-connection protection prevents damage if the balance lead is plugged in backwards.

Continuous buzzer and red LED alarm under load

When any cell drops below the chosen threshold the tester sounds a continuous buzzer and flashes a red LED, giving an unmistakable warning during sustained discharge rather than a momentary beep. The alarm remains active until the pack is disconnected or the voltage recovers above the set point. Users who require silent monitoring or a higher cell-count display will need a different instrument.

Questions about this item

What does the 0.01 V precision mean when I plug this tester into a 6S pack?

It shows each cell voltage to two decimal places so you can spot a drifting cell before it drops below the 3.3 V default alarm threshold.

The alarm works from 2S to 8S — what does that limit in practice?

You can set the buzzer trigger anywhere from 2.7 V to 3.8 V per cell, but the monitor will not sound an alarm on a single-cell pack.

The unit measures 4 × 2.5 × 1.1 cm — what mounting clearance does that need?

Allow roughly that footprint plus room for the balance lead; the tester weighs 45 g and has no built-in mounts.
