The wire harness safely connects to standard Peg-Perego 12-volt SLA and lithium battery riding toys. Dual Safety Upgrades: The power wheel converter features 12 AWG thick copper wiring and a 40A fuse for improved conductivity and safety. The heavy-gauge wire supports higher current flow, while the included fuse holder protects against transient current surges, helping prevent damage to the battery and equipment.
