The Beast 48 LE replacement battery for golf carts refers to high-performance 48V lithium iron phosphate (LiFePO4) batteries designed as upgrades for lead-acid systems. Optimal replacements like the 48V150Ah or 48V200Ah models provide 7.68–9.6kWh capacities with 5-year warranties and 6,000+ cycles. These utilize smart BMS protection and IP65 enclosures for thermal stability, making them compatible with golf carts requiring sustained torque and 40–60 km ranges per charge. Key specs include ≤2-hour fast-charging and -20°C~60°C operating ranges.

What voltage and capacity define Beast 48 LE replacements?
True replacements operate at 48V nominal voltage (51.2V fully charged) with capacities from 100Ah to 200Ah. JRE POWER’s 48V150Ah model delivers 7.68kWh—20% more than standard lead-acid packs.
A standard Beast 48 LE replacement maintains 51.2V (±0.5V) under load, critical for preventing motor controller errors. Pro Tip: Verify your cart’s motor controller accepts up to 54V input—some older models can’t handle LiFePO4’s higher float voltages. For example, a 48V200Ah battery with 10.24kWh capacity extends runtime to 8 hours in hilly terrains.
| Capacity | Energy | Range |
|---|---|---|
| 100Ah | 5.12kWh | 35–45 km |
| 150Ah | 7.68kWh | 55–70 km |
| 200Ah | 10.24kWh | 75–90 km |
How do LiFePO4 batteries outperform lead-acid?
LiFePO4 cells offer 6,000+ cycles vs. 500–800 in lead-acid, with 95% depth of discharge (DoD) compatibility. They weigh 60% less—48V150Ah packs average 42kg vs. 120kg for equivalent lead.
These batteries maintain stable voltage under 200A+ loads, unlike lead-acid’s 15% voltage sag. Practically speaking, carts accelerate 20% faster uphill with lithium packs. Pro Tip: Use low-temp charging blankets below 0°C—BMS systems may disable charging otherwise. A real-world test showed LiFePO4-powered carts completing 27 holes on one charge vs. 18 with lead-acid.
What certifications ensure safety and compatibility?
Top replacements hold CE, UN38.3, and UL certifications, with BMS systems monitoring temperature, overcurrent, and cell balance. JRE POWER models include IP65 waterproofing for rain-resistant operation.
UN38.3 certification guarantees stability during impacts—a must for golf carts traversing uneven terrain. Pro Tip: Check for built-in cell balancing—unbalanced 48V packs lose 30% capacity within 200 cycles. For example, certified batteries withstand 12G vibration tests equivalent to driving over 10,000 potholes.
| Feature | LiFePO4 | Lead-Acid |
|---|---|---|
| Cycle Life | 6,000 | 800 |
| Weight (48V150Ah) | 42kg | 120kg |
| Charge Time | 2 hrs | 8 hrs |

Choosing the Best Electric Golf Trolley
FAQs
Yes if your cart’s battery tray fits 328×178×270mm dimensions (standard 48V150Ah size). Always disconnect the main breaker first—48V DC can deliver lethal shocks.
Do lithium batteries require cooling systems?
Not below 150Ah—built-in BMS manages heat up to 60°C. For 200Ah+ packs, add a 12V fan if ambient temps exceed 40°C regularly.
