Chargeur 42V 2A : convient-il à une batterie 36V Li-ion ?

Yes, this 42V 2A charger is only compatible with 36V-rated lithium-ion batteries designed for a charging voltage of 42V, with a 4-pin XLR connector and matching polarity.

Quelle est la polarité du connecteur XLR 4P ?

The polarity specified for this model is pin 1 = positive (+) and pin 4 = negative (-). Always check the polarity of the old charger or battery before connecting it.

Ce chargeur peut-il être utilisé sur une batterie LiFePO4 ?

No. This charger is designed for 36V Li-ion batteries. It must not be used with LiFePO4, lead-acid, NiMH, or NiCd batteries, or any battery requiring a different voltage.

À quoi correspondent les voyants rouge et vert ?

The red light usually indicates that charging is in progress. The green light indicates that charging is complete or that the charger is in standby mode, depending on the battery's status.

Que vérifier avant de commander ce chargeur XLR 4P ?

Before placing an order, verify the 42V charging voltage, the Li-ion chemistry, the 4-pin XLR connector, the polarity (pin 1 + / pin 4 -), the battery’s current rating, and the presence of a suitable BMS.

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.
