Golf Cart Lithium Batteries

• Avoid: SOC <20%

• Recommended: Top up allowed at 40%–50% SOC; frequent shallow charging acceptable

• Caution: No long-term undercharge (<80% consistently); optimal target 90%–100%; unplug after full charge (overcharge not a concern)

Core Logic

1. Cycle life advantage: Shallow discharge reduces wear (e.g., 50%→100% = 0.5 cycles; 20%→100% = 0.8 cycles) → extend lifespan

2. Risks: Long-term undercharge → loss of active lithium & cell voltage imbalance; deep discharge → BMS lockout or permanent damage

3. Difference from lead-acid: No harm from frequent charge starts/stops; shallow charging avoids deep discharge → extend life (opposite of lead-acid)
