My 5000mah just came today and as soon as I tried to plug it I got the error code (reverse polarity)

    Follow the colored wires and make sure red goes to red and black goes to black from the charger to the battery. Sometimes if you try to charge without a battery connected it spikes the output higher than normal and when you connect a battery it forces the output circuitry of the charger negative a little and can give that error. Turn it off, wait a few minutes and try again.
