6700mAh Battery for Xiaomi Roborock S5,S6,S7,S8 Max/Max V/Max Ultra/Pure, S50, S51, S55, Q5/Q7 Max+, brr-2p4s-5200s, 1st and 2nd Generation Robot Vacuum Cleaner

Works fine in S5 Max, happy with it!

The battery is not working properly. While cleaning at 44% battery, the robot completely shut down and won't turn off. I have never had a single case like this with the previous battery which was from new in the robot almost 3 years. People on Reddit are writing about the same problem where the robots just shuts down on this brand battery. Only after manually putting it in the charger does it start up. This is not a correct operation. It is not worth buying this replacement if the works shuts down and will not start up without your help. Fatal crap.

Does what it says. Would recommend
