EZ-GO Freedom SE electric carts require 48V battery systems for optimal performance. These typically use lead-acid or lithium-ion configurations with 150Ah capacity, delivering sustained power for all-terrain use. The battery bank consists of six 8V lead-acid units in series or a single lithium pack, supporting 80–120 km per charge. Pro Tip: Always verify terminal orientation and tray dimensions—mismatched batteries may cause controller errors or physical incompatibility.
What Makes 1275 Golf Cart Batteries a Top Choice for Power?
What voltage requirements define EZ-GO Freedom SE batteries?
The Freedom SE operates on a 48V DC system requiring six 8V lead-acid batteries or equivalent lithium packs. Voltage deviations exceeding ±3% (46.5–49.5V range) trigger performance throttling through the cart’s onboard controller. For lithium conversions, BMS must regulate cell balancing to prevent premature cutoff during steep inclines.
What physical dimensions ensure battery compatibility?
Standard EZ-GO battery trays accommodate L10 terminal orientation batteries measuring 10.3″L × 7.1″W × 10.9″H. Lithium replacements like Redway’s RL-48V150 use compact form factors (8.7″L × 6.3″W × 8.5″H) but require adapter plates. Weight varies from 62 lbs (lithium) to 168 lbs (flooded lead-acid), demanding chassis reinforcement for heavy chemistries.
| Parameter | Lead-Acid | Lithium |
|---|---|---|
| Cycle Life | 400–600 | 3,000+ |
| Charge Time | 8–10h | 4–5h |
| Weight per Unit | 28–32kg | 11–15kg |

How does amp-hour capacity affect runtime?
A 150Ah battery at 48V provides 7.2kWh energy, sustaining 2.5h continuous hill climbing (300A draw). Higher 170Ah models extend range 15–20% but require modified battery trays. Lithium batteries maintain 95% capacity below -10°C, whereas lead-acid drops to 60%—critical for winter operations.
What safety certifications are mandatory?
UL 2580 and UN38.3 certifications are non-negotiable for lithium batteries—ensuring crash safety and thermal stability. Lead-acid replacements should meet SAE J537 standards with flame-arresting vent caps. Always check for OEM approval codes (e.g., EZGO P/N 609146) to bypass controller compatibility issues.

FAQs
No—eight 6V batteries would exceed voltage limits (51.2V full charge), triggering controller faults. Stick to six 8V units for proper voltage alignment.
Do lithium batteries void EZ-GO warranties?
Only if installed without OEM-approved voltage regulators. Use certified 48V lithium packs with dynamic load balancing to preserve warranty coverage.
