I am interested in sourcing battery management systems for 12V configurations, specifically 4-series and 8-series setups, with a capacity of 250 Ah. It's crucial for us to have reliable systems that can handle the required power efficiently and ensure the safety of our battery packs. Could you provide details about your offerings, including technical specifications, pricing, minimum order quantities, and lead times for delivery? Additionally, any information on warranty terms and after-sales support would be greatly appreciated. Looking forward to your response!
