The two are not the same though. Laptop batteries are made down to a price and
driven pretty hard, whereas aviation batteries are built and tested to a very
demanding spec and will be used well within ratings.
Looking at the spec for the charger, it looks like each cell in the battery is
monitored and is confirmed by the additional thin wire harness within the battery.
Not clear if this includes individual temperature and voltage monitoring for each cell.
Also looks like there is no separate charge circuit per cell, just the the single
pair for the overall cell group. While this isn't optimum in terms of battery
management, it is cheaper and less bulky. I would have thought that they would
have gone the extra mile with this, but they must have had their reasons...
