Battery upgrade for Xiaomi Mi Robot Vacuum Mop

hello,
did anyone test the F9 battery?
I found this link
https://shopee.com.my/Xiaomi-Roborock-Vacuum-1C-(STYTJ01ZHM)-battery-5600mAh-i.53020293.6671942157
not sure if it is trustworthy, the video shows another robot cleaner

Roborock S5/S6 batteries may work

Thanks a lot for the answer, this is exactly what I was also able to find out, the battery of the Dreame F9 may also fit 1C, I have not seen evidence that anyone has already done it but it seems logical to me to compare the voltages between the battery terminals and see if they give the same voltage, in general I found replacement batteries in AliExpress such as this

I bought and it should arrive in the next few days, I will update as soon as it arrives ....

Hi,
I tried to find any information about the larger battery for the 1C, but no success. I believe a larger battery replacement will be available on the market in the near future. There is another robot vacuum identical to the 1C, the Dreame F9 which has a 5200mAh battery. Both robot vacuums were made by Dreame (a startup in the Xiaomi ecological chain) so there is a chance that the Dreame battery can fit the 1C, but I was not able to find any proof of this.
