Like propellers, LiPo batteries are a consumable in the hobby, however they should last longer than your props, as long as you treat them well! I mentioned internal resistance earlier, this is what kills your batteries over time. The more you use a LiPo, the more the internal resistance increases. Internal resistance can be thought of as a component within your battery that uses electrical energy, leaving less power for your motors. Zhang, J., Wu, B., Li, Z. & Huang, J.
