Versatile: The cell counter has multiple functions as it can display estimated voltages for LiPo or LiFe or Li-ion packs (2-7 cells) and single cells and NiCd or NiMH batteries for TX and RX ( 4-7 cells). The battery capacity checker can quickly check the estimated capacities of the lithium battery pack and indicate whether it needs to be recharged before use.Battery type: NiCd or NiMH (4 to 7 cells), lithium type (2 to 7 cells) Display mode: battery cell voltages, total voltages, lowest cell voltage, highest cell voltage deviation between the highest cell voltage and lowest cell voltage, remaining battery capacity ( percent ).Application: Applies to check the batteries. It is very convenient to read your cell voltage. High quality, safe and durable, tiny and compact, easy to understand and operate. High quality and lightweight with excellent performance. Warranty: We trust the cell counter. Let every buyer satisfaction and enjoy a pleasant shopping experience here. Note: The data are all manual measurement, please allow 1-3cm error, due to the light difference and display, there will be some color difference, depending on the physical item received.
