BEFORE YOU SPECIFYYour 48V battery
Your 48V battery
questions, answered.
Where are 48V lithium batteries commonly used?
48V is the most common voltage platform for golf carts, electric trikes, solar storage and utility vehicles. Match the battery’s actual voltage, current and interfaces to the equipment; voltage class alone does not establish compatibility.
How long does a 48V LiFePO4 battery last?
Expect 4000–6000 cycles, or 8–12 years of daily use, depending on discharge depth and maintenance. The technical reference states 4000–6000+ cycles at 80% DOD; confirm the test conditions and end-of-life criterion for the selected model.
Can I customize the capacity or shape?
Yes. Robur offers 48V modules from 60Ah to 200Ah, custom enclosures and BMS protocols. The six catalogue configurations above are separate starting points; share your required capacity, dimensions and system details for engineering review.
Why replace lead-acid with a 48V lithium battery?
Lithium batteries are 60% lighter, charge 3× faster and deliver constant voltage output throughout the discharge cycle. Check the comparison conditions and the charger, controller and mounting requirements for your specific upgrade.
How quickly can you supply 48V batteries?
Standard 48V models are stocked for OEMs, with standard products shipped within 24 hours. Typical custom projects are delivered in 7–15 days; large custom orders usually ship within 25–35 days. The schedule for your configuration and order is confirmed in the quotation.
Is a 48V battery the same as a 51.2V battery?
Here, 48V is the system class and 51.2V is the nominal voltage of the 16S LiFePO4 configuration. The 100Ah example stores 5.12kWh and specifies a 58.4V ± 0.2V charge cut-off. Confirm the voltage window and communication profile with your equipment and charger.
