Which Batteries Can This Charger Charge?

This charger is designed for compatible 36V lithium-ion battery packs that require a 42V charging voltage.

A typical 36V lithium-ion e-bike battery reaches approximately 42V when fully charged. However, matching voltage alone does not guarantee compatibility.

Before connecting the charger, verify:

Your battery's manufacturer-specified charging voltage is 42V.
The battery uses compatible lithium-ion chemistry.
The charging connector fits correctly.
Connector polarity matches the battery requirements.
The battery manufacturer permits a 2A charging current.

Do not use this charger for 48V, 52V, 60V, or 72V lithium-ion battery packs unless the battery manufacturer explicitly specifies a 42V charging input—which would be unusual for those nominal voltages.

Do not use it with lead-acid batteries.

Five Connector Configurations

The package includes a main 5.5 × 2.5mm DC charging plug and four adapters:

5.5mm single-prong DC plug
8mm three-prong connector adapter
12mm three-prong connector adapter
8mm RCA connector adapter
3-pin male XLR connector adapter

The adapters provide different physical connector options, but they do not guarantee compatibility with every battery using those connector styles. Always verify the exact pin arrangement and polarity.

Simple LED Charging Indicators

According to the supplier, the indicator light operates as follows:

Green: Charger is connected to AC power but is not charging, or the battery is fully charged.
Red: Battery is charging.
Green again: Charging is complete, according to the supplier.

Indicator behavior can vary with the charger design. Follow the included manufacturer's instructions and disconnect the charger when required.

How to Use

Confirm that your battery requires a 42V lithium-ion charger.
Select the connector that matches your battery's charging port and verify polarity.
Connect the charger's AC cord to a suitable power outlet.
Connect the DC plug to the battery according to the manufacturer's instructions.
Monitor the charging indicator and follow the battery manufacturer's charging guidance.
Disconnect the charger when charging is complete, as directed by the manufacturer.

Charge in a dry, well-ventilated location. Do not use the charger in wet conditions or if the cable, connector, or housing is damaged. Do not leave a charging battery unattended unless the manufacturer specifically permits it.
