LiPo Voltage Tester 1S - 8S digital and programmable. This voltage tester shows you the condition of your battery, or rather the cells, within seconds. It is suitable for 1-8S LiPo, Li-ion, LiMn, and Li-Fe. The voltage measurement has an accuracy of ± 0.01 V. The 1S test mode has a voltage range of 4-15 V. There is a low voltage alarm mode for 2-8S with an alarm setpoint range of 2.7-3.8 V. The weight is 9 g.

Features: The display shows the total voltage (all cells) as well as the individual voltage of each cell. During operation, the battery tester monitors the battery. The individual cells are continuously checked for their voltage, and the alarm is triggered automatically when the set cell voltage is reached or falls below. Connect a battery (1-8 cells LiPo) to the balance connector of the battery tester. The voltage tester acknowledges the connection of the battery with two short beeps. The display shows the total voltage of the battery in volts and then switches to the voltage of the individual cells (No 1, No 2, No 3, etc.).

Setting the alarm for the desired cell voltage: Press the button once. The tester will display the currently set voltage value in volts (based on 1 cell). If this value meets your requirement, the programming is complete, and the battery tester will return to the default display. If you want to change the alarm value, press the button twice. The battery tester will switch to the next possible value. Repeat this step until the desired setting is displayed.

Programming options: OFF / 2.70 V to 3.8 V in increments of 0.10 V. Press the button once = display of the set alarm value. Press the button twice = switch to the next value. By pressing the button multiple times, you can scroll through all values.

Recommendation: The alarm value should not be set below 3.3 volts, as LiPo batteries are very sensitive to deep discharge.
