Lithium-Polymer and Nickel-Metal Hybrid batteries use completely different technologies and have different chemical properties that enable battery charging. The one thing that both technologies share in common is that they are both capable of storing a fixed amount of energy depending on the listed capacity. Both LiPo and NiMH batteries are manufactured at different voltages and capacities, and their use cases are identical. But which technology comes out on top when compared? Let’s find out.
NiMH batteries are much easier to use and come with very simplistic chargers. They need to be fully discharged before being disposed or storing for extended periods of time. There are manufacturers that have managed to bypass the storage and disposal requirements by using safety shells, but they are mostly exceptions and not part of the majority of the NiMH industry.
LiPo batteries, on the other hand, can be stored at anything between a 50% to 70% charge levels without any risks. They do not need to be fully discharged for safety reasons. While LiPo batteries require specific chargers (known as balance chargers), the popularity of the technology makes the chargers easily accessible for nearly every appliance that the batteries are used in.
When it comes to the environmental impact caused by both technologies, LiPo is much safer for the environment compared to any other type of battery technology out there. The batteries are also safe for users, and using them extensively does not cause any health risks. Over time, it is expected that Lithium-Ion and LiPo batteries will be used to power a sizeable percentage of vehicles around the world as industries are trying to move away from fossil fuels.
