The 5RH Pro I purchased on PDD became noticeably hot and felt like a short circuit when I touched the battery while transmitting. It's not just a slight increase in temperature; it's clearly uncomfortable. I initially planned to return it to the seller, but they said that several other units they had also exhibited this behavior, so I gave up. Does anyone else experience this? My other QuanSheng K6 and BaoFeng UV5R haven't shown any similar issues.
