42V 2A XLR 4P Charger for 36V Li-ion Battery

42V 2A XLR 4P Charger for 36V Li-ion Battery

This 42V 2A charger is designed to recharge the 36V lithium-ion batteries used in certain electric scooters, electric bikes, and compatible mobility devices.

The 42V output corresponds to the end-of-charge voltage of a 36V lithium-ion battery in a 10S configuration. The 2A charging current is suitable for many Li-ion packs used in light mobility applications, provided the battery supports this voltage, current, and connector type.

This model is equipped with a 4-pin XLR connector. The polarity for this charger is: pin 1 = positive (+) and pin 4 = negative (-). It is essential to verify this polarity before connecting the charger, as 4-pin XLR connectors are not always wired the same way depending on the manufacturer.

Important Information Before Ordering

Before purchasing, be sure to check the charging voltage, battery type, connector, polarity, and the current rating of your battery. This charger is designed for a 36V Li-ion battery that charges at 42V.

Do not use with lead-acid, NiMH, NiCd, LiFePO4, 24V lithium, 48V lithium, or any other battery requiring a different voltage. An incorrect voltage or polarity can damage the battery, the BMS, or the charger.

The polarity ( pin 1 = + and pin 4 = - ) should be compared with your old charger or checked with a multimeter before connecting.
