🔌 3-Pin XLR to Small 3-Pin Juliet Battery Charger Adapter

Compatible with 48V • 52V • 60V • 72V Battery Systems

⚡ The Simple Charger Solution

If your e-bike battery uses the small 3-pin Juliet charging port and you are struggling to find a replacement charger with the correct connector, this adapter provides a simple and cost-effective solution.

It allows you to use a more commonly available 3-pin XLR battery charger with a battery fitted with the smaller 3-pin Juliet charging connection.

Perfect alternative: Rather than paying a premium for a specialist charger fitted with the small Juliet connector, you can use this adapter with a suitable 3-pin XLR charger.

🔋 Battery Compatibility

Designed for batteries using the small waterproof-style 3-pin Juliet charging port, including batteries such as:

  • ✔️ HS11 style e-bike batteries
  • ✔️ Tishen wedge-shaped batteries
  • ✔️ Compatible 48V battery systems
  • ✔️ Compatible 52V battery systems
  • ✔️ Compatible 60V battery systems
  • ✔️ Compatible 72V battery systems
Important: Battery voltage alone does not determine charger compatibility. Your charger must have the correct output voltage and polarity for your battery.

If the plug on your existing or replacement charger is the larger 3-pin XLR type, this adapter converts the connection so it can be connected to a compatible battery using the smaller 3-pin Juliet charging port.

⚡ Suitable Charger Current

Suitable for use with compatible chargers rated at:

2A 3A 4A 5A

Always ensure the battery and its BMS are designed to accept the charging current supplied by your charger.
