Batteries and charging
Battery and charging problems sit at the top of the fault list for electric golf carts, and the guides in this category work through the common patterns: a charger that stays silent, a charger that clicks but never starts charging, shrinking range, corroded terminals, watering and testing routines, lithium packs asleep after storage, and packs that drain overnight. Start with the pack before you blame the charger. Automatic chargers need to see a minimum voltage before they will begin a cycle, so a deeply discharged pack can make a working charger appear dead. When rested, a full 48 volt lead-acid pack usually reads close to 50.9 volts, and a reading below roughly 48.5 volts means the pack is significantly discharged. Measure each battery on its own with a multimeter; a single failed battery pulls the whole pack down and shows up clearly against its neighbors. Check that the wall outlet is live and the charger fuse is intact before condemning the charger itself, and inspect the terminals for green or white crust, which adds resistance and generates heat. Voltage checks, watering, and terminal cleaning are reasonable owner jobs with basic care around the pack. If a battery case is swollen, a cable runs hot at its post, or you smell burning, stop working on the vehicle and send us the details through our support request form.
Guides for this system are being written and reviewed now. The troubleshooter below can point you to the right checks in the meantime.
