Battery saw solution

[ZERO]

@HumBurner the trick to fast charging is disconnect when the last led is blinking. Up to about 3/4 any charger will do, last 1/4 where all chargers have to slow down, heat and cell over voltage, two big enemies.

I stopped counting, but about 400 full cycles with the QC80, 3 years on the 200, thus far no shortened life on the battery.
