美国采购需求：15kwh锂电池，15kwh太阳能电池，48v 300ah太阳能电池，48v 300ah锂电池，15kwh太阳能电池，48v 300ah锂电池

I have a 48v ebike battery that uses lithium-ion cells. Unfortunately, it has suffered from water damage, but I'm relieved to report that it remains fully charged. However, I've noticed some rust corrosion developing on the connection plate and inside the battery. I'm looking for recommendations on the best spray or solution to clean the corrosion effectively while also providing protection against future damage. Could you suggest a reliable cleaner that will help restore the battery's condition and possibly enhance its longevity? Additionally, if there are any specific products known for preventing further corrosion, I'd love to hear about those as well. Thanks for your assistance on this matter!
