🔋 42V Charger Compatibility

A 42V charger is commonly used with 36V nominal lithium-ion batteries.

For a typical 36V lithium-ion battery:

36V nominal → 42V fully charged

Before ordering, check the label on your battery or your original charger. The required charger voltage should match 42V DC.

⚠️ Important Compatibility Warning

Do not use this charger simply because your battery is labeled "36V." Confirm that your battery is a compatible 36V lithium-ion system requiring a 42V charger.

Also verify:

• Charging voltage: 42V

• Charging current requirements

• DC connector size

• Connector polarity

• Battery chemistry

• Charger plug configuration

Never use a 42V charger on a battery that requires a different charging voltage.
