The 1-8S Lipo Battery Voltage Tester plugs directly into the balance connector of a LiPo, LiFe, Li-Ion, or LiMn pack and displays the voltage of every individual cell alongside the total pack voltage simultaneously. The Voltage Tester handles packs from 1 cell up to 8 cells in series covering 1S single-cell packs at 3.7V through 8S packs at up to 33.6V fully charged. Reading individual cell voltages tells the operator something a simple pack voltage measurement cannot, which cells are balanced and which are diverging from the others, because an imbalanced pack can show a normal total voltage while one cell sits dangerously low and another sits high.
The battery voltage tester cell voltage display range of 0.5V to 4.5V covers the full discharge-to-full-charge window of standard lithium chemistries. A cell reading below 3.5V on a lithium pack warrants immediate attention, and a reading below 3V indicates deep discharge damage has likely already occurred. The 1S test mode expands single-wire voltage range to 3.7V to 30V for single-wire voltage checks on larger packs without a balance connector.
The lipo checker powers itself from the measured battery through the balance plug no USB cable or separate power source is needed to use it in the field. The lipo rc battery tester is a pre-flight and post-flight essential for RC aircraft, drone, and ground vehicle maintaining multi-cell lithium packs. This battery voltage tester is working on LiPo battery management and pack health monitoring. Available on StemVolt.
