How to Charge 48 Volt Golf Cart Batteries

Charging your 48V golf cart batteries properly ensures longevity and peak performance. Modern lithium batteries like LiFePO4 require specific charging protocols – here’s your no-nonsense guide.

Step 1: Match Voltage & Chemistry Always use a charger designed for 48V LiFePO4 systems. Lead-acid chargers can damage lithium batteries. The ideal charger delivers 58.4V (full charge voltage for 48V LiFePO4 packs) at 18A for efficient charging.

Step 2: Connection Sequence

1. Power OFF cart
2. Connect charger to battery first
3. Plug charger into outlet
   Reverse order when disconnecting. This prevents voltage spikes.

Pro Tips:

• Charge after every use (lithium has no “memory effect”)
• Store at 50-80% charge if inactive >1 month
• Avoid full discharges below 20% capacity

Troubleshooting:

• Charger not starting? Check battery voltage – most LiFePO4 chargers activate only above 40V.
• Slow charging? Ambient temps below 32°F/0°C trigger protection modes.
