For a limited time, SmallRig is selling orange batteries for various camera models (see the complete list here):
"SmallRig's color event has just started. In response to users' demand in August, we launched colorfed camera cages, which were a huge hit selling out in just one day. This time, we have extended colors to other products, introducing colorful V-Mount batteries, camera batteries, and cages featuring Halloween-themed orange, as well as red, green, and blue."
