Yesterday I was doing a taxi test and had the following happen more than once. This scares me enough that I am now very hesitant to use a Lipo with BMS. After about five minutes of taxi, my engine shut off as if the ignition switch had been shut off. There was absolutely no power at the ignition switch. The BMS took over and shut the system down. After about 10 minutes, The battery came back to life and she started right up. Only to again shut down after a few minutes of running. Why is this happening? Is it due to the Dynamo? Why wouldn't my engine keep running just off the Dynamo. Does the BMS somehow disable the entire system? I am feeling like Larry Flesner said. I think I too will only fly with AGM batteries. Seems this BMS in Lipo batteries is a source of failure we do not need.
