How do you wash a golf cart with an IP67-rated lithium battery without damaging it?

Direct answer: Do not pressure-wash the battery area. IP67 under IEC 60529 means dust-tight and protected in a temporary-immersion test in fresh water; it is not a rating for powerful or hot water jets. Switch the cart off, keep the jet away from the battery, connectors, vent, charge port, controller and wiring, rinse that area by hand at low pressure or wipe it, and let it dry before charging.

What the pages say. The 48V 100Ah, 48V 150Ah and 72V 160Ah golf cart pages list IP67, a metal shell, a vent and a power switch. The pages do not say which parts of the system (cables, plugs, display, charge port) carry that rating.

What IP67 means. Under IEC 60529 the first digit 6 is dust-tight and the second digit 7 is protection against the effects of temporary immersion, tested between 0.15 m and 1 m of water. The standard notes that tests use fresh water and that protection may not be satisfactory with high-pressure, high-temperature jets outside the numeral 9 test. An enclosure rated only IPX7 is not considered suitable for water jets unless it is also rated 5 or 6. So IP67 is no promise against a pressure washer.

The rest of the cart matters more. The motor controller, solenoid, wiring looms, charge receptacle and accessories are usually not rated like the pack. Water forced into a connector or charge port can cause corrosion or faults later.

A wash routine. Switch the cart off and set the battery power switch off if your procedure allows. Cover the charge port. Wash body and wheels as usual, but keep any jet well away from the battery bay. Clean the battery area with a damp cloth or a gentle low-pressure rinse, never aimed at plugs, the vent or seals. Do not use solvents on seals or labels.

Drying and checks. Let the cart dry before plugging it in. Weekly, check connectors and the charge port for water, corrosion or green deposits, and check that cable glands and covers are seated. If water got into a connector or the case shows damage, do not charge it; contact support.
