I purchased a MEAN WELL USA Inc. / PB-360P-48 charger recently from Digi-Key. I have a 16S LifePo4 battery pack. I have connected a 16 awg wire from the positive terminal of the charger to the positive post of the battery. When I attempt to attach a 16 awg wire to the negative terminal, it sparks. This is prior to even plugging the charger into a receptacle or powering up the charger. The batteries are connected in series correctly and my BMS works properly.
Any idea of why this is happening or do you think I might have a faulty battery charger?
