Common Types of RC Batteries

1. NiMH (Nickel Metal Hydride) Batteries

NiMH batteries have been widely used in the RC world for many years. They are known for their balanced performance and affordability. Here are some key features:

  • Voltage: Typically 1.2V per cell
  • Capacity: Ranges from 1000mAh to over 5000mAh
  • Weight: Generally heavier than LiPo batteries
  • Life Cycle: 300-500 charge cycles

Advantages:

  • More robust than NiCd batteries
  • Less prone to memory effect compared to NiCd
  • Relatively inexpensive

Disadvantages:

  • Heavier than lithium batteries
  • Lower energy density

2. LiPo (Lithium Polymer) Batteries

LiPo batteries have surged in popularity due to their lightweight design and high energy density. They are a favorite among competitive hobbyists. Here are some features:

  • Voltage: 3.7V per cell
  • Capacity: Can exceed 6000mAh
  • Weight: Much lighter than NiMH
  • Life Cycle: 200-300 charge cycles

Advantages:

  • High discharge rates for performance
  • Lightweight and compact
  • Customizable shapes and sizes

Disadvantages:

  • More expensive than NiMH
  • Requires careful handling and charging

3. NiCd (Nickel Cadmium) Batteries

Though less common today, NiCd batteries still have a presence in certain niches. They are reliable in various temperatures and have a unique set of traits:

  • Voltage: 1.2V per cell
  • Capacity: Typically between 600mAh and 3000mAh
  • Weight: Heavier than NiMH and LiPo
  • Life Cycle: Around 1000 charge cycles

Advantages:

  • Very durable and robust
  • Performs well under extreme conditions

Disadvantages:

  • Suffers from memory effect
  • Environmental concerns with cadmium content
