Hello, if your radio transmits at 50W, the actual current may be greater than 10A. This means that your battery can discharge at 10A, and your cables support 10A. Also, check if your fuse allows for 10A.
Additionally, please note that generally, it is not allowed to transmit frequencies above 30MHz with a power greater than 25W. Please ensure you have obtained the necessary permits. If transmitting at 25W, the current will likely be less than 10A, possibly between 5A and 8A. Refer to your radio's manual and perform actual testing for specific details.
