Q. What are the differences between the built-in lithium battery tubular motor with the other DC tubular motor?

A. Built-in lithium battery tubular motors (25LE and 28LEQ) don't need wiring or an electrician, they are most popular tubular motors for motorised roller blind by far. They just need to be plugged into the charger when necessary. If the position of the roller blind is high and hard to reach, the solar recharging panel would be a suitable option. The built in Lithium battery has the ability to be charged up to 500 times, the fully charged battery can run up and down 150~600 times depending on the size and weight of the roller blinds. For the average usage, it can last 3~6 months per charge.

The DM25TE Model DC tubular motor has a built-in transformer. It needs to be connected to a regular main AC. If there is no power cable nearby, you might need a registered electrician.

The price of the AC powered tubular motor is cheaper than battery powered one, but if you consider to the cost you hire a electrician to wire the power cable and do connection work, then the total cost would be quite similar between these two options.
