美国采购需求：汽车电池、锂离子电池、电池充电器、电子自行车、电动摩托车、电池充电器

I recently purchased an e-bike and I'm really enjoying longer rides, but I've realized that I need a backup battery to extend my trips without worrying about running out of power. I'm interested in finding out if your company specializes in e-bike batteries and if you have options available for purchase. Could you provide me with more details about the types of batteries you offer for e-bikes? I'm particularly interested in the specifications, compatibility with my current e-bike, and any pricing information. Additionally, if there are different capacities or features available, I'd love to hear about those as well. Looking forward to your response!
