Yes that is correct......that is why I was asking if the Hyperion charger he used was a peak detecting charger. It might explain why he smoked his A9.
If he was charging at 120ma that in itself wouldn't smoke the board unless he overcharged the pack.
If I recall the charger that comes with the A9 charges at 80ma.
