She uses very fresh batteries and has an ultrasonic welder to make the
packs.
Excellent but a comment:
Many battery rebuilders recycles the old straps besides special

In many cases the weird little hardware bits are simply unavailable, so
what do you do, recycle metal parts or buy new battery packs?
