I have this moped with a dead battery, i need one, and the only one i could find that is in stock, is a 4Ah battery pack. Can i use this battery as a replacement for a 12V 5Ah battery pack?
From the electrical point of view, yes - it does have 20 percent less nominal capacity (4Ah vs. 5 Ah), but it is still better than a dead battery. Before buying check also its physical size, type and layout of terminals - they should be the same as the original battery, otherwise it will be difficult to install.
