We're looking to source batteries with specific capacities—one type at 75 Ah and another at 100 Ah. Could you provide us with your pricing, availability, and any bulk order discounts you might offer? Additionally, it would be great to know about the delivery timelines and warranty details for these batteries. We're keen to establish a reliable partnership and appreciate any info you can share. Thanks!
