Note that this 12V 7Ah battery comes with wires soldered to battery and large style connector and fuse together on harness. It is same version originally shipped with Big Toys Direct LaFerrari and may or may not be compatible with others. Some battery versions from other suppliers may have shipped with small connector so you would need to verify this before purchasing as parts cannot be returned. Do not buy batteries for "future use" since they lose charging capacity sitting on shelf for 1-2 years.
Please note that all parts sales are final and no returns are allowed.
