Same principle as bulbs, building a discharger out of resistors is another way to get things done. I built this one to use with my chargers that have external discharge discharge function.

Good old 20 amp bulb discharger from the 90's... and a few minutes will take care of things. If, and when I don't use a pack that has been charged, I'll use a LiPo alarm and the bulb discharger to quickly bring down the voltage close to storage voltage (approx. 3.75v/cell) and let a charger...

Amen, brother. I don't use a charger's discharging feature for any great length time, because it puts a lot of stress (heat) on the internals, and just 'cause it takes forever. Chargers that we use are not really designed for discharging with great power. If they were, they'd be huge, because of...
