Hi.
My scooter is an EVT 4000e BLM, European version. Originally it was equipped with lead batteries, but I have replaced these with LiFePO4 batteries from Ping Battery.
Recently I have bought a Canada controller to get more speed, but I run into a problem when installing it.
When I turned the scooter on after replacing the controller the first red LED on the dashboard lit, and I got no response when turning the throttle. According to the user manual this indicates a battery pack breakdown on lithium models. When I reinstalled the old controller everything was working as intended.
The old controller are for lead batteries, and the new for lithium, but they looks the same, and even have the same model number (BLM-0299-2801). But obviously the lithium controller are expecting some signal from the BMS that the lead controller doesn’t need.
Does anybody know how to simulate the missing signal, or to turn this test off in the controller?
