I had the v8, the v8f then the v8s yesterday.The v8 cut off easily before the safety.The v8f never cut off but had a power alert which worked quite well around 2500w.Today first v8s test in high climb with 72 % of battery, there was security (overload please go down), there was a current peak at 36A! I think we should put a 40A or 35A fuse or a v10 motherboard.
