Feature:1. Support Battery Types: Our battery detector balancing discharger supports battery types for LiPo, LiFe, Li ion, NiCd, NiMH, using a wide range of batteries.2. Testing Accuracy: The battery voltage testing accuracy of the battery detector balancer discharger is 0.001V, which is good and can be used for more accurate reference.3. Multi Purpose: Battery detector balancing discharger can also can be used as a servo tester to test standard and narrow servo.4. Display Mode: Battery voltage, total voltage, minimum battery voltage, maximum battery voltage, voltage difference between maximum battery voltage and minimum battery voltage, remaining battery capacity.5. Check Voltage: The battery tester balancer discharger servo tester is easy to use and perfect for checking voltage before parallel charging.Specification:Item Type: Battery DetectorMaterial: ABSBattery detector is a detection instrument that can detect the status of the battery, the detection battery type contains most rechargeable batteries. Battery types areLi Ion (Lithium Ion Batteries)Li Po (Lithium Polymers Batteries)Li Fe (Lithium Iron Batteries)Ni Cd (Nickel Cadmium Batteries)NiMH (Nickel Metal Hydride)Li Ion battery types (Li Po, Li Ion, Li Fe), without additional power supply battery detector can support 2S-8S.Test 1S lithium battery, then you need to access greater than 3S nickel batteries or UBEC 5V to NiCd or MH port to provide operating power for the battery detector.Nickel battery type (NiCd or NiMH), the battery detector can support 4S-8S without additional power supply.If you need to test nickel batteries smaller than 4S, you need to access 2-8S lithium battery to Lithium port to provide working power for the battery detector..Package List:1 x Digital Battery Capacity Checker1 x Manual
