This is HIGHLY ill advisable. Leaving your golf cart plugged in 24/7 is a bad idea. It may give you the peace of mind that it’s “ready to go” at the drop of a hat, but what this does is open up room for a potential disaster. In the event of a thunderstorm, having your golf cart on charge provides a direct route for a power surge and catastrophically damage your charger among other things. OEM items are not cheap, and replacing these all at once would be roughly $1,200 or more before tax. The best practice is to plan for inclement weather whenever possible by unplugging your charger from the cart AND the wall after a full charge.
