美国采购需求：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 looking to order a smart battery management system that integrates seamlessly with communication protocols for household energy storage. Specifically, I need a model with robust functionality, including features like Bluetooth monitoring and protection for a 4S 12V configuration that can handle a 300A load. Recently, I encountered an issue where the system has been tripping unexpectedly. I'm seeking assistance to understand the potential causes and any recommendations you might have for troubleshooting or replacement options. Please provide details on availability, pricing, and delivery timelines for the required components.
