12 hours ago12 hr Hello, I have this device and I want to update its firmware. My problem is that when I press the Enter key and navigate to code 29, the battery voltage shows 48 volts, and I can't control the remaining battery percentage. I want an update that allows me to control the percentage at which the device shuts down. The current firmware on the device is U17404/U22225.I need a suitable, modern presentation program that supports SoC% for settings 29.Thank you... Edited 12 hours ago12 hr by AN solar
