I disagree, it’s highly unlikely that any such battery pack will be subjected to such high current discharge as to become dangerous – far too much engineering has taken place to prevent that from happening in the first place. That’s the reason for the -1/3 EOL estimate, because at that point, the battery starts to wear out faster and faster under constant use. That said, the simplest battery management is a shunt over the cell to prevent its voltage from ever rising over about 4.1-4.2 volts. $26.99 $ 26. If “power” was intended, the units should read “half of a kilowatt.” If you don’t know what was intended (among current, potential, power, energy, etc. You can get away with a lot in something like a remote control, but in a high-current application you have an opportunity to rupture a cell. I iterated the effect once however, and concluded that if you set a certain min/max distance, say 40 miles that you have to drive 5 days a week and you can do with no more, the linear model actually gives you a useful battery life within +10…+15% of what you should actually expect.
