1-8S Lipo Battery Voltage Tester

The 1-8S LiPo Battery Voltage Tester is a compact plug-in tester that connects to the JST-XH balance connector of any 1S to 8S LiPo, LiFe, Li-Ion, or LiMn battery pack and instantly displays the voltage of each individual cell alongside the total pack voltage — providing the essential pre-flight safety check that every drone pilot should perform before flying to confirm all cells are adequately charged and balanced before connecting the battery to the flight system.

The lipo battery voltage tester displays individual cell voltages from 0.5V to 4.5V and total pack voltages from 3.7V to 36V, covering every LiPo pack from 1S hobby packs through 8S high-voltage systems including all the 3S drone packs. The 1-8s lipo battery tester connects directly to the balance plug without any separate power source — the battery under test powers the tester itself.

This makes the battery voltage tester the fastest pre-flight checking tool available, taking under five seconds to plug in, read all cell voltages, confirm balance, and unplug before arming the drone. A significant cell voltage difference between cells on the same pack (typically more than 0.1V variation) is an immediate indicator that the pack needs balance charging before flying. This voltage tester is perfect for 2S 3S LiPo battery RC drone quadcopter and cell balance safety check. Available from StemVolt.
