NiCd VS. Lipo Battery: Which is Better?

In the RC hobby, NiCd and LiPo batteries are commonly used rechargeable batteries. However, their biggest difference lies in performance, with LiPo batteries offering higher charge and discharge rates and longer run times. Beyond this, there are many other differences. Let’s dive in and analyze them in detail.

NiCd VS. Lipo Battery

Discharge Power

High-power-demand brushless RC models typically use LiPo batteries because they provide higher voltage and greater discharge current, resulting in increased discharge power. Entry-level RC models and toys, which often have lower power requirements and use brushed power systems, tend to use NiCd, NiMH, or Li-ion batteries. Besides, these batteries are also less expensive to manufacture.

Charging Time

LiPo batteries support fast charging and can usually be fully charged in about an hour. In contrast, NiCd batteries often require a longer charging time.

Capacity (mAh)

Due to the higher energy density of LiPo batteries, they can offer greater capacity within the same volume compared to other types of batteries.

Weight and Size

LiPo batteries are lighter and more compact, making them the top choice for RC models with strict weight requirements.

Durability and Cycle Life

The chemical composition of NiCd batteries is less reactive than that of LiPo batteries, making them less sensitive to temperature variations. LiPo batteries, however, perform poorly in high or low-temperature environments and can have their lifespan significantly reduced if misused.


In conclusion, LiPo batteries offer better performance but require careful handling, making them ideal for dedicated RC hobbyists. NiCd batteries, on the other hand, are more affordable and durable but offer lower performance, making them more suitable for beginners.
