I am looking to source standard cases for two popular voltage packs: one at 48V and the other at 72V. Additionally, I require these cases to accommodate battery capacities of 142Ah and 280Ah, respectively. It's crucial that the cases are suitable for these specifications to ensure compatibility and functionality. In terms of aesthetics, I would prefer the cases to be in a vibrant yellow color, which is essential for our branding purposes. Please provide details on pricing, minimum order quantities, lead times, and any other relevant information regarding your products. I am eager to establish a productive partnership and look forward to your prompt response. Thank you!
