意大利采购需求：电池管理系统，BMS电池，BMS模块，锂BMS，BMS锂电池，适用于Lifepo4的BMS

I'm really interested in your BMS and would love to get more details. Could you please provide the manual and specs? I'm particularly curious if it has a power ON/OFF switch and whether it can automatically turn off to prevent discharge during extended periods of inactivity. Additionally, does the BMS support CAN Bus connections for saving battery usage parameters in our system? We're looking to purchase 20 units every three months, so your prompt response would be appreciated!
