斯里兰卡采购需求：机架式电池 48V电池组 锂电池 储能解决方案 备用电源 不间断电源

I'm reaching out with an inquiry regarding battery solutions. Specifically, I'm interested in two types: a 48V model with a capacity of 300Ah and another 48V option offering a capacity of 500Ah. These products are intended for use in Sri Lanka, and I would appreciate any information you can provide about their availability, specifications, and pricing. Additionally, if you have options for related accessories or services that could enhance these battery systems, I would love to hear about those as well. Please include lead times for delivery and any bulk order discounts you might offer. Looking forward to your prompt response so we can potentially move forward with an order.
