I'm looking for a reliable supplier for a specific type of battery that operates at 48V with a capacity of 500Ah. It's crucial for my project that these batteries are not only efficient but also durable and ready for regular usage. Could you provide me with your pricing, minimum order quantity, and lead times for delivery? In addition to that, it would be helpful if you could share any available certifications, warranty details, and options for bulk purchasing. Please also include information on the battery's cycle life and performance in various conditions. Looking forward to hearing from you soon!
