The QS138 70H V3 motor has been a strong and reliable motor for us DIY builders. They have just made some significant upgrades to that motor. Here is the information from the AliExpress website. It is hard to differentiate the new from the old. They list and explain all the improvements on the included AliExpress link. The improvements include better waterproofing, bigger bearings on most bearings, bigger gear in the gear reduction, different cables for waterproofing, and I think a little more "beef" in the gear reduction case. You can identify the new motor by the new cover on the encoder side of the motor, (better waterproofing), and the nub that got near the output sprocket, is now gone. If you order thru AliExpress, and I have a lot, be sure to always use the best shipping method, DHL or FED EX. Always click on the Delivery box to see your options. Also to learn more about all the improvements, scroll down and click "View More" and they have great explanations.
