What kind of batteries for ezgo golf cart?

EZGO golf carts typically use deep-cycle lead-acid or lithium-ion batteries, with voltage configurations ranging from 36V to 48V depending on the model. Lithium options like LiFePO4 dominate modern upgrades due to 4x longer lifespan (2,000+ cycles) and 50% weight reduction. For traditional setups, Trojan T-875 (8V) or Interstate GC2 (6V) flooded lead-acid batteries remain popular, requiring regular watering but offering lower upfront costs. Always match battery voltage to your cart’s motor controller—common configurations include 6x6V or 6x8V for 36V systems.

What voltage system does EZGO use?

Most EZGO carts operate on 36V or 48V systems. Older TXT models use 36V (6x6V batteries), while RXV series often require 48V (6x8V or 4x12V). Lithium upgrades like 36V 100Ah packs maintain compatibility while eliminating series wiring complexities. Pro Tip: Check your charger’s output voltage—48V systems need 58-64V chargers to prevent undercharging.

EZGO’s electrical architecture dictates strict voltage parameters. A 36V system actually operates between 32V (discharged) and 45V (charged), with controllers programmed for these thresholds. Using mismatched voltages risks motor burnout—for instance, a 48V lithium pack (nominal 51.2V) could overpower a 36V controller. Real-world example: The 2018 EZGO Express L6 accepts 72V lithium systems, but only with factory-approved motor/controller upgrades. Transitional tip: If upgrading voltage, replace all batteries simultaneously to prevent cell imbalance.

Lead-acid vs. lithium: Which lasts longer?

Lithium batteries outperform lead-acid with 2,000+ cycles vs. 500-800 cycles. They maintain 80% capacity after 5 years versus lead-acid’s 2-3 year lifespan. Lithium also charges 3x faster (2-3 hours) and operates at 95% efficiency vs. 75-85% for flooded batteries.

How to calculate runtime?

Runtime (hours) = (Ah × Voltage) ÷ Power Draw. A 36V 100Ah lithium pack provides 3.6kWh energy. If your cart draws 500W, runtime = 3,600Wh ÷ 500W = 7.2 hours. Pro Tip: Lithium maintains voltage better under load—expect 20% more usable capacity than lead-acid’s 50% DoD limit.

Beyond basic math, consider terrain and payload. Climbing 10° hills increases power draw by 40%, reducing runtime proportionally. Real-world example: An EZGO TXT with 36V 105Ah lead-acid batteries lasts 25 miles on flat courses but only 15 miles in hilly areas. Transitional note: Lithium’s flat discharge curve means speed stays consistent until 90% depletion, unlike lead-acid’s gradual slowdown. Ever wonder why your cart slows down before “empty”? That’s voltage sag in lead-acid chemistry!
