🔋 How to Charge the 48V SLA Battery Pack in Your Roma or Genoa EuroScooter
Your Roma or Genoa EuroScooter runs on a reliable 48V battery system composed of four 12V 12Ah Sealed Lead Acid (SLA) batteries wired in series. This configuration delivers the power you need for smooth, dependable rides—but it’s essential to charge and maintain these batteries correctly to get the most life out of them.
🧠 Understanding the Battery Setup
Each Roma and Genoa scooter includes:
4 x 12V 12Ah SLA batteries
Wired in series to create a 48V power system
Charging all four batteries together using the correct charger is critical. Charging improperly can reduce battery life, impact performance, and lead to costly replacements.
⚡ Recommended Charger Specs
Use a charger specifically designed for 48V SLA batteries:
Output Voltage: ~54.6V (fully charges all four batteries)
Charging Current: Between 1.5A and 5A
Type: SLA-compatible charger (AGM/Gel type), with automatic shut-off
Avoid lithium-specific chargers, as they are not compatible with SLA chemistry and could be dangerous if used.
✅ How to Charge the Battery Pack
Power off your scooter before charging.
Plug the charger into the scooter’s charging port (this accesses the entire 48V battery pack).
Connect the charger to a wall outlet.
Let the charger run until it indicates a full charge (typically a green light).
Disconnect the charger from the wall, then from the scooter.
🔌 Never attempt to charge individual 12V batteries while they're still connected in series—always charge the pack as a whole.
🧼 Battery Maintenance Tips
Proper battery care goes a long way in extending the lifespan of your SLA battery pack. Follow these tips to keep your Roma or Genoa scooter performing at its best:
🔄 Regular Charging
Always charge the battery after each use, even if you didn’t fully drain it.
If the scooter isn’t being used regularly, charge the battery at least once every 2–4 weeks to prevent deep discharge.
🌡️ Storage Conditions
Store fully charged in a cool, dry place.
Avoid high temperatures and direct sunlight—heat is one of the biggest enemies of SLA battery life.
In winter or cold conditions, store indoors to prevent freezing and voltage drops.
🧠 Smart Charging
Use a smart charger with automatic voltage regulation and shut-off.
Do not leave the battery connected to a charger for extended periods unless the charger is designed for float/trickle charging.
🚫 Avoid Full Discharges
SLA batteries degrade more quickly when they are fully drained often.
Recharge when the charge drops below 50%, and avoid running the battery completely flat.
🔍 Routine Inspections
Periodically check the charging port and cables for signs of corrosion, dirt, or damage.
Inspect the battery casing for swelling or leaks—if you notice anything unusual, replace the battery pack immediately.
🚀 Keep Your Ride Charged and Ready
Charging your Roma or Genoa scooter the right way—and taking good care of the battery—ensures you enjoy longer rides, fewer breakdowns, and a longer battery lifespan. Treat your battery right, and it will return the favor mile after mile.
