澳大利亚采购需求：3FM5电池，6V5Ah电池，20Hr电池，6V充电电池，密封铅酸电池，免维护电池

I'm exploring potential suppliers for batteries as I plan to launch a resale business in Australia. Initially, I'm looking to place an order for 50 units to gauge the market demand. I would appreciate it if you could provide me with the purchase price for this quantity, along with any applicable shipping costs and lead times. Additionally, I'm interested in learning more about the technical advantages of your batteries. Understanding their performance and features will help me position them effectively to my customers. Looking forward to your prompt response on pricing and any relevant product details.
