Dear Friend. Nice to see your Robot weeder. Im chamika , Expert Electronic engineer with extensive knowledge of drones and robotics . As we are using Lifeo4 it need better Battery management system. and also charging circuits must be safe enough to auto shut down if over charge . I have done similar project to my auto charging drone system. We used Li ion that is more unsafe compare to Lifeo4. If you like to discuss and do the project contact me. Cheers!!

Hello. I call it the "doubles case law." Just now I am working on a similar project (the similarity lies in the voltage and current values, as well as in the batteries used). I don’t want to write much about me. If you want - see my portfolio. There are several works related to power supply. In more detail we could discuss your task in the chat. Thanks in advance for your reply!
