This 58.8V 3A charger is a mains-powered battery charger built for 14S lithium-ion battery packs, commonly labelled as 52V class. It charges up to a full-charge voltage of approximately 58.8 V and delivers a steady 3 A charging current. The unit fits electric bikes and electric scooters that run on 14S Li-ion packs.
A 52 V nominal rating and a 58.8 V full-charge rating describe the same battery. The 58.8 V figure comes from 14 series-connected cell groups at 4.2 V each. For that reason, this charger is not adjustable and not universal. It is made specifically for the 14S Li-ion configuration, so compatibility depends on cell count and chemistry rather than the brand of your vehicle.
The charging connector is prepared to your specification. Simply write the connector model you need in your order comments. We solder and prepare the matching lead, so you receive a plug-and-play solution with no rework needed on your side.
Key Benefits
- 14S Li-ion compatibility – suits 52V class packs that reach roughly 58.8 V at full charge.
- 3 A charging current – a measured balance between charging time and long-term battery life.
- LED status indicator – red shows charging in progress, green shows a full pack or an unconnected charger.
- Active fan cooling – housing temperature stays stable through longer charging sessions.
- Connector of your choice – XLR, GX16, DC 5.5×2.1 mm or any other model you specify.
- Compact housing – the charger slips easily into a backpack or a bike bag.
- Plug and play preparation – the lead arrives with the connector already fitted, so charging can start straight away.
- Dual application – works equally well with e-bike and e-scooter 14S packs.
Who Is This Charger For?
This 58.8V 3A charger is intended for electric bikes (e-bikes) and electric scooters (e-scooters) fitted with a 14S Li-ion battery. Compatibility is determined by cell count and cell chemistry, not by the make of the vehicle. Consequently, the charger suits any 14S Li-ion pack whose BMS accepts a 3 A current.
Many riders keep it as a spare charger at home, at work or while travelling. It also serves well as a replacement charger when the original unit has failed or gone missing. Because charging speed stays moderate, the pack sees less stress than it would under a high-current unit.
Battery builders and pack assemblers find it convenient too. Since the connector is chosen per project, the same charger model can be matched to different builds without extra adapters or splices.
What Is in the Box?

Why Choose This Charger
The main differentiator is the made-to-order connector. Rather than shipping a generic barrel plug and leaving you to splice it, we solder the connector you name in your order comments. As a result, the charger works with your pack from the first minute.
Active cooling is the second practical advantage. A fan and vented housing keep the case temperature steady during longer sessions, which matters when a larger 14S pack takes several hours to fill. Meanwhile, the LED gives a clear read on charge status without any guesswork.
Finally, the 3 A rating is a deliberate choice. Faster chargers push more heat into the cells, while this current keeps the pack comfortable and still finishes charging within a practical window.
How to Use the 58.8V 3A Charger
First, connect the charger to the battery. Then plug the mains cable into the wall socket. Before that, check that polarity and connector type match your battery and its BMS.
Charge in a well-ventilated area on a non-flammable surface. The housing has ventilation openings and a fan, so never cover the unit while it works. When charging finishes, disconnect the mains first and only then unplug the battery. That order is not a formality – it reduces sparking at the DC connector.
Frequently Asked Questions
Will this charger work with my 52V e-bike battery?
- Yes, provided the pack is a 14S Li-ion configuration.
- 52 V nominal and 58.8 V full charge describe the same battery.
- Your BMS must accept a 3 A charging current.
Can I use it on an electric scooter?
- Yes, it suits e-scooters with 14S Li-ion packs.
- Vehicle brand does not affect compatibility.
- Cell count and chemistry decide the match.
Is the charging voltage adjustable?
- No, the output is fixed at approximately 58.8 V.
- The unit is built for the 14S Li-ion configuration only.
- It is not a universal or multi-voltage charger.
Which connector will I receive?
- The one you name in your order comments.
- XLR, GX16 and DC 5.5×2.1 mm are common choices.
- We solder the lead before dispatch.
What do the LED colours mean?
- Red indicates charging in progress.
- Green indicates a full pack or a charger that is not connected.
How long does charging take?
- The 3 A current sets the pace.
- Charging time depends on your pack capacity and its starting charge.
Where should I charge the battery?
- Indoors, in a well-ventilated room.
- On a non-flammable surface, with the housing left uncovered.
Can I use it as a replacement charger?
- Yes, it replaces a lost or failed 14S Li-ion charger.
- It also works well as a second charger for travel or the office.
With a fixed 58.8 V output, a 3 A current, fan cooling and a connector soldered to your specification, this charger arrives ready for your 14S Li-ion e-bike or e-scooter pack. Just add your connector model in the order comments and we will prepare the lead accordingly.
