I'm looking for a solution to effectively manage hot swapping between two batteries, likely in the 20V range. It's crucial for my application that the product ensures seamless transitions without interrupting power supply. Additionally, I'm interested in understanding the key features, specifications, and any relevant certifications that might apply to your product. If you have such a device, could you provide detailed information on its compatibility, performance metrics, and pricing? I would appreciate a prompt response primarily via email, as I won't be available for phone discussions. Looking forward to your insights!
