I'm looking for a Battery Management System (BMS) specifically designed for graphene batteries. The system should support 120V with a capacity of 100Ah and be capable of handling charge/discharge rates between 300-500A. Additionally, the configuration I need is 40S4P. Could you please provide me with your recommendations based on these specifications? I'm interested in understanding the features, compatibility, and any additional options you might offer. It would be great to get a quote and lead time as well. Thanks!
