Thanks Gordon, thats what I thought. When I copied out the info sheet for her, it said:
(Plug the charger input plug into your AC power outlet (before plugging the charger into the battery).

I'm looking for a replacement for my original battery from a bafang addon kit. That battery was a 48v 11.6ah (557wj). Is the 48v 14ah ultra slim battery (lg 3500 18650 cells) compatible?

She took her battery and charger to a bike shop. They've seen this before and suggested plugging into the battery first, otherwise they saw no major problems. She was worried about "burning down the house", so she used the outlet in the garage. No spark... Without being there, I am unable to...
She lives 3 hours away. I told her to take the cable to the nearest bike shop that handles ebikes and they might be able to point her in the right direction.
