Battery types are Li Ion (Lithium Ion Batteries) Li Po (Lithium Polymers Batteries) Li Fe (Lithium Iron Batteries) Ni Cd ( Batteries) NiMH ( Metal Hydride) Li Ion battery types (Li Po, Li Ion, Li Fe), without additional power supply battery detector can support 2S-8S. Test 1S , then you need to access greater than 3S batteries or UBEC 5V to NiCd or MH port to provide operating power for the battery detector. battery type (NiCd or NiMH), the battery detector can support 4S-8S without additional power supply. If you need to test batteries smaller than 4S, you need to access 2-8S to Lithium port to provide working power for the battery detector. How to Use: Just
