48v Battery Not Charging with New 54.6V Charger

I just purchased a new 54.6V lithium battery charger off aliexpress (https://www.aliexpress.com/item/32870181959.html?spm=a2g0s.9042311.0.0.2c5a4c4drNIsiM).

The charger LED indicators light up, but the actively charging indicator light stays green and the fan off. The battery is a Dehawk 48v 16ah lithium battery which works with another charger with the same specs. When I test the charger with a multimeter is shows 54.6V. I tested the two fuses it comes with as well.

Does anyone have any idea why the charger won't start charging with my battery?

What is the voltage of your battery pack, measured with your multimeter?

Haven't tested the battery with a multimeter but the specs are posted here https://www.leoncycle.com.au/~140

Would this charger be compatible with that battery? (not the same as the aliexpress one linked earlier)

Not sure if you want the output reading, but I measured 52.5

OK, I seem to have solved my own issue. The AC switch was not set correctly on the charger.
