I'm looking to procure battery cells and a BMS controller for our upcoming project. It's crucial that the cells meet our specific energy density and performance requirements to ensure optimal efficiency. Additionally, please provide details on the BMS controller, particularly its features like communication protocol, voltage range, and any safety certifications. If you have any recommendations or package deals, I'd love to hear about those as well. Looking forward to your prompt response!
