I'm looking for a high-capacity e-bike battery that meets specific performance needs. The ideal product should be a compact model with robust durability and exceptional output. Key specs include a nominal voltage of 52V and around 50A discharge current, along with a good energy-optimized design. I'd appreciate detailed information regarding the battery's manufacture and any certifications it holds. Please include pricing, minimum order quantities, delivery times, and any available warranties or service support. Looking forward to your prompt response!
