BMS
Same port charge and discharge balance PCM for 36V
- B-: Connect to the negative pole of the battery pack
- P-: No Connect
- C-: Connect to the negative electrode of charge and discharge
Please connect B- line firstly, and then connect voltage monitoring wiring harness. The last step is to connect charge and discharge lines. If you want to remove them, the order should be reversed. Please pay attention to the connection order, or it will damage the component.

turbo levo
- il bms viene attivato da una tensione di controllo di 5v sul cavo marrone
- a bms attivo compare 12v sul cavo arancione
- il caricabatterie viene attivato da NTC sul pin ?
- I dati sono fondamentalmente “little endian”, cioè a1 fe ff ff è 0xFFFFFEA1.
- Corrente, tensione e i valori di capacità sono per lo più “volte 1000”
combinazione non funzionante scheda massimo: motore 5.0.4, bms 2.23.1
