48V 5A Charger – 13s Li-ion Charger for E-Bikes and E-Scooters

The 48V 5A charger is a 13s lithium-ion battery charger built for electric bikes, electric scooters and other 48 V micromobility vehicles. It works in constant current / constant voltage mode, delivers up to 5 A of output current and finishes the cycle at 54.6 V. An LED indicator and an integrated cooling fan are built into the housing.

This charger is matched specifically to 48 V class Li-ion packs made from 13 cells wired in series. Such a configuration reaches 54.6 V when fully charged, because 13 × 4.2 V equals exactly that figure. Therefore the charging profile lines up precisely with what a 13s pack needs.

Approximate charging power reaches around 273 W (54.6 V × 5 A). As a result, this is a mid-speed charger suited to everyday charging of an e-bike or e-scooter battery. In addition, the built-in fan holds the housing at a steady temperature throughout the whole session.

Key Benefits

• 13s Li-ion charging profile – CC/CV operation with a 54.6 V full-charge voltage.
• 5 A output current – mid-speed charging for 48 V micromobility batteries.
• LED indicator – red shows charging in progress, green shows a full pack or no battery connected.
• Active cooling – the fan keeps the temperature stable and supports a longer service life.
• Broad application – suits e-bikes, e-scooters and other 48 V equipment.
• Connector made to order – the charging plug is selected to match your battery socket.
• Stable charging – output voltage stays consistent across the entire cycle.
• Compact power supply – one self-contained unit with no extra modules required.

Who Is This Charger For?

This 48V 5A charger is intended for electric bikes and electric scooters whose battery is a 48 V Li-ion pack in 13s configuration. Furthermore, it fits other micromobility vehicles that use a battery of the same class.

The charger is equally useful for other equipment running on 48 V power, provided the pack is a 13s lithium-ion type. Before connecting, it is important to know your own pack configuration. For example, a 13s pack charges fully to 54.6 V.

The charger is not suitable for 48 V lead-acid or gel batteries. It is also not suitable for LiFePO4 packs, because their full-charge voltage differs. Consequently, those systems require a different charger.

What Is in the Box?

• 48V 5A charger – 13s Li-ion charger with LED indicator and cooling fan.
• Charging connector made to order, where applicable.

Technical Specifications

Why Choose This 48V 5A Charger?

This unit has a precisely defined end-of-charge voltage of 54.6 V. Therefore it is not a plain power adapter. The CC/CV mode ends the cycle at the moment a 13s pack reaches its full voltage.

The first distinguishing feature is active cooling. Many lower-current chargers rely only on passive heat transfer through the casing. Here an integrated fan does the work, so temperature stays steady even under a 5 A load.

The second distinguishing feature is the made-to-order connector. Simply state your charging plug model in the order comments. As a result, the charger arrives ready for the socket already fitted to your bike or scooter.

Frequently Asked Questions

Does this charger suit a 13s (48 V) Li-ion battery?

• Yes, it is designed specifically for 48 V Li-ion systems in 13s configuration.
• The end-of-charge voltage of 54.6 V matches 13 cells at 4.2 V each.

Can I use it with an e-bike or an e-scooter?

• Yes, it covers electric bikes and electric scooters with 48 V Li-ion packs.
• Other 48 V micromobility vehicles with 13s packs work as well.

How fast does it charge?

• Output current is 5 A, giving roughly 273 W of charging power.
• That places it in the mid-speed category for daily use.

What do the LED colours mean?

• Red indicates that charging is in progress.
• Green indicates a fully charged pack or no battery connected.

Is it suitable for lead-acid or gel batteries?

• No, it does not suit 48 V lead-acid or gel batteries.
• Those chemistries need a charger with a different voltage profile.

Will it charge a LiFePO4 battery?

• No, LiFePO4 packs have a different full-charge voltage.
• Use a dedicated LiFePO4 charger for those systems instead.

Does it get hot during long sessions?

• An integrated fan provides active cooling throughout the cycle.
• Housing temperature therefore stays steady even at the full 5 A load.

Which charging plug will I receive?

• The connector is chosen to match your battery charging socket.
• Specify the plug model in your order comments.

Check your pack configuration before connecting, since this charger targets 13s Li-ion batteries only. With its 54.6 V end voltage, 5 A output and fan cooling, it covers regular charging duty for 48 V electric bikes and scooters. Add your connector type to the order notes and it will arrive ready to plug in.
