Why 42V 2A Is Used for 36V E-Bike Batteries
Many buyers ask why a 36V e-bike battery needs a 42V charger. In lithium battery systems 36V is the nominal battery voltage while 42V is the full-charge voltage. That is why a 42V 2A e-bike charger is commonly used for 36V e-bike lithium battery packs.

For Qwic battery systems you should still confirm the original charger label before ordering. A 4-pin XLR e-bike charger may look right. The real match depends on output voltage charging current, connector, pin layout and polarity.
Connector Matching Is the Important Step
For any 4-pin XLR e-bike charger connector matching is the first step. The 4-pin XLR connector must fit the battery charging port. The pin layout must match. The polarity must match. The cable length should be suitable for the user. The AC plug standard should match the target market.
