Lithium Battery Capacity Indicator 3S12.6V LED Display, Battery Power Tester, 1Pcs

Lithium Battery Capacity Indicator 3S12.6V LED Display, Battery Power Tester, 1Pcs Description

Realtime battery capacity display: a digital display tube shows the remaining charge of a lithium battery pack, providing a clear and continuous readout of battery status. Simple wiring and setup: connect the display board's positive and negative terminals to the battery's positive and negative terminals; the readout updates in real time when connected to a tested battery. Size and compatibility: designed for 3S packs with a voltage up to 12.6V (3S12.6V), suitable for a range of lithium batteries. Broad lithium battery applicability: widely compatible with lithium battery configurations that fall within the 3S12.6V range. Practical use scenarios: In RC hobby packs (cars, boats, airplanes, drones) to monitor remaining capacity during operation. In DIY portable power banks or backup power systems built from 3S Liion cells to provide a live voltage/readout. In power tools or other lithium battery assemblies that require simple stateofcharge indication to prevent deep discharge.
