Hi Hilo. It's good to hear that you are far from the volcano action in Hawaii. Do you feel any earthquakes in your area?
I've worked with Lithium batteries since their inception. Insomuch, I would strongly recommend that you not use any device (other than the discharge electronics in the drone battery) to discharge your battery with. Mr. yrless (above) is right on. Each and every Lithium battery is designed around certain, and very specific parameters (needed/operating current draw, desired charging time, and discharge rates). Modifying any of those parameters can not only result in battery failure, but, with Lithium batteries, it can result in an explosion or a flame-up. I'm not saying that will happen. But, the risk that it will happen is greatly increased. With Ni-Cad and NickelMetalHydride batteries, there was much more flexibility. One might ask, why then, are Lithium batteries so popular now? The answer is that they (lithium) deliver more current, more evenly, for a longer period of time. Also, as lithium battery current is consumed, voltage does not decrease, which is very preferential to the electronics it is powering. I personally, would recommend against trying to second-guess the operation and capabilities of the discharge electronics and firmware in your drone battery.
Keep the beautiful Hawaii pictures coming. Not only are you in a beautiful place, but you are fortunate to have a drone that helps you share such a place with others!
