Micro RC helicopters require small, lightweight batteries that provide sufficient power without adding too much weight to the aircraft. Here are some commonly used battery types for micro RC helicopters:
1. Lithium-Polymer (LiPo) Batteries:
- LiPo batteries are the most popular choice for micro RC helicopters due to their high power density, lightweight design, and relatively low discharge rates.
- They come in various capacities and discharge rates, allowing you to choose the right battery based on your helicopter's power requirements and flight time preferences.
- LiPo batteries require proper handling, charging, and storage to ensure safety and longevity.
2. Lithium-Ion (Li-Ion) Batteries:
- Li-Ion batteries are another common option for micro RC helicopters. They offer good energy density and have built-in protection against overcharging and discharging.
- However, Li-Ion batteries are typically heavier than LiPo batteries of similar capacities.
3. Alkaline Batteries:
- Alkaline batteries are sometimes used in micro RC helicopters as a cost-effective option. They are relatively inexpensive, easy to find, and do not require special chargers.
- However, alkaline batteries have a lower energy density compared to LiPo and Li-Ion batteries and may not provide sufficient power for more demanding flight maneuvers.
4. NiMH Batteries:
- NiMH (Nickel-Metal Hydride) batteries are another less common option for micro RC helicopters. They offer good reliability, reasonable energy density, and can withstand higher discharge rates than alkaline batteries.
- However, NiMH batteries are heavier than LiPo and Li-Ion batteries and have a higher self-discharge rate.
When selecting batteries for your micro RC helicopter, it's important to consider the helicopter's power requirements, flight time expectations, and the overall weight of the battery to ensure optimal performance and flight stability.
