Ecooter E2 BMS protocol

[freesty]

Thanks for the pdf.
In case you might not know, the communication between main and second battery happens on 2x extra wires, probably UART RX/TX between both BMS. The middle pins of the original battery connector.
And ecooter did some bms updates, to improve second battery behaviour.

Are you gonne stay with 64V or go higher?

Thanks man, nice to know. i was suspecting it to talk on the same wire. I was planning to go to 32s9p so about 134V fully charged
