Common Questions
Is this tester compatible with all balance plugs?
It is designed for standard LiPo balance leads used on most hobby and consumer battery packs. If your pack uses a proprietary connector, use an adapter cable that provides a standard balance plug.
Does the tester require its own battery?
No. The tester draws power from the connected LiPo pack for displaying voltages and powering the alarm during testing.
Can this prevent all battery failures?
While it helps detect low cell voltages and balance issues to reduce the risk of failure, it cannot prevent every type of battery fault. Use this tester as part of a regular maintenance routine along with proper charging and storage practices.
Keep your LiPo batteries safe and reliable with quick per-cell checks and audible low voltage alerts. The 1S-8S LiPo Battery Voltage Tester is a compact, effective tool for hobbyists and professionals who depend on LiPo power.
