I'm trying to upgrade my scooter range by adding a battery.
I've two m365 batteries.
I tried to connect the two batteries in parallel. but only one battery data cable is connect to the main board.
I used this cable:

But, when I turned the sccooter on the additional battery led turns to red instead of fast flashing.
Any Idea what I'm doing wrong?
Thx
Granted it's not the m365, but I am currently running 2 ninebot ES batteries(front post battery) in parallel and connected only 1 bms to the controller(wired to the external port) along with another single with its bms connected. So far have not had any issues arise.
Did you wire them together with their capacities equal or drained and are they identical batteries? Its been documented that varying gaps in the charge of both batteries being connected could lead to taxing the healthier unit. And for most use case scenarios, not recommended to parallel different capacity units together.
For the ES batteries, I am only aware of the red led signalling in the event of low charge or when the bms detects some type of fault(such as over current or high temp. Etc)
I hope you solve the issue soon
