Brand Skyrc Model SK-500007 Quantity 1 Piece(s)/pack Color Blue + grey Material Plastic Compatible device RC car Functions Voltage check Other Feature SKYRC LiPoPal is a simply used battery checker and self voltage balancer. When we are flying or running outside it is difficult to know the remaining capacity of the battery. With this tiny LiPoPal we could check the voltage of each cell and the remaining capacity in percentage at anytime and anywhere. As we know if each cell of the battery pack is balanced the battery performance will be much better and the cycle life will be longer. But sometimes we don't have time or tool to balance the battery cell. With this small kit when it detects the pack is not balanced it will start work to balance the pack cell at once; Functions: There are two functions of this compact device: 1. Battery Checker: The LiPoPal can check the voltage of each cell of a lithium battery pack and remaining capacity in percentage; 2. Self Voltage Balancer: This program can equalize the individual voltages to their lowest one. Balance operation automatically starts about 5 seconds after the battery pack is connected. When the voltage difference between cells over 0.02V the balancer will start to work. The corresponding V will be blinking when it is balancing. When the voltage difference between cells reaches 0.01V or less balance operation ends and the device enters the sleep mode and SLP will be displayed on the LCD. How to use? Simply connect the battery pack to 7 pins connector (XH type). Please note the negative lead or pin of the LiPo connector should match the Negative marked on the shell of LiPoPal. After the LiPo is connected the LCD display the voltage of each cell; Specification: Applicable Battery Pack: 2~6S LiPo; Voltage Display Tolerance: +/- 1.5%; Voltage Display Resolution: 0.01V; Voltage Display Range: 0~5V; Balancing Current: 50mA; Operating Temperature: 10~+45'C; Storage Temperature: -20~+60'C; Size: 7 x 3.8 x 1cm; Net Weight: 21g Packing List 1 x Voltage checker 1 x FlightPower / thunder power adapter (7.5cm-cable) 1 x Wrist strap (19.5cm) 1 x English user manual
