Energy density is how much energy a battery contains in proportion to its volume (Wh/L). Another way to think of energy density is as the amount of runtime in relation to the battery''s size. Higher energy density means a smaller battery that can store more energy which is always a good thing. Battery power is defined in Wh (Watt Hours).
If you charge your battery pack to 4 volts per cell and stop using it when it reaches around 2.8 volts per cell, then your battery pack will have a lifespan that is 2 to 3 times longer while having a capacity only around 20 percent less. You can build a lithium battery charger to customize the charge current and voltage. Conclusion
