It connects directly to the balance connector on your battery pack for an instant voltage reading of each individual cell as well as the total pack voltage.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How does the buzzer alarm work on this low voltage tester?\u003c\/h4\u003e\n\u003cp\u003eA: The built-in buzzer alarm activates automatically when any individual cell voltage drops below the preset low-voltage threshold. This audible alert helps you avoid over-discharging your battery, which can permanently reduce capacity or damage the pack. Simply connect the tester to your battery's balance port during use to monitor it in real time.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the battery tester difficult to set up or use?\u003c\/h4\u003e\n\u003cp\u003eA: Not at all — this tester is completely plug-and-play. Just plug your battery's balance connector into the corresponding port on the tester and it immediately displays cell and total pack voltage on the LED screen. No tools, wiring, or programming required. Its compact 40mm × 25mm × 11mm size makes it easy to carry in your RC gear bag.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What battery types is this 1–8S battery tester compatible with?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This 2-in-1 battery tester is compatible with LiPo, Li-ion, and LiFe battery packs ranging from 1S to 8S.
