Hi all,

Just got my BBS02B 750W this evening, with battery 48v from ALiexpress _https://fr.aliexpress.com/store/1379035?spm=a2g0w.12010608.0.0.73be7d01YEEAho_ i connected it up to the bike, plugged battery in and turned it on to setup the hydraulic brake sensors, it turned on fine, all good , 52v shown on display, so i start setting up position of the brake sensor and the display goes off by itself for no reason, did not come back since, checked everything i could, battery is fine, power goes in, all pins seem ok, i checked the pins in the green cable going to the display and i see a 50v reading on pin 1 and 3, is that normal? Tried to wait 5 min disconnected to see if it would come back but nothing. I messaged the seller but no answer yet. Any suggestion? Please help, very disappointed, I spent loads and waited 18 days for it!!

Thanks,

Lucio
