None of the 20.xx firmwares that I have is rated at 3.5 kW.But please tell us what brand of lithium battery you want to connect to.21 hours ago, ahmad almawal said:U2 : 2.68The problem is not connecting to the lithium battery.Since it's a communications issue, it could well be the display firmware. 02.68 would be about 4 years old. The latest I know of is 02.87, available from the below linked post. Ignore the King 1 main firmware; King 1 and VM III (older) share the same display/comms firmware.
