Battery for RC model Receiver and Transmitter, the battery voltage range 4.8v 6.0v 7.2v etc, mainly use battery model 2/3A NiMH battery cell. 1000mAh to 2000mAh.

Characteristics of NiMH Batteries

    NiMH (Nickel Metal Hydride) batteries are rechargeable batteries that are commonly used in RC receiver applications due to their high energy density and low self-discharge rate. They typically have a voltage range of 4.8V to 9.6V and are available in various capacities ranging from 600mAh to 5000mAh.

    One essential characteristic of NiMH batteries is their memory effect, which occurs when the battery is not fully discharged before recharging. This can lead to a decrease in the battery's capacity over time, ultimately reducing its overall performance. To prevent memory effect, it is recommended to fully discharge the battery before recharging it.

Advantages of NiMH Batteries

    One of the significant advantages of NiMH batteries is their high energy density, which allows them to store more energy per unit volume than other battery types. This means that they can provide more power to your RC vehicle or aircraft, resulting in longer run times.

    Another advantage is their low self-discharge rate, which allows them to hold their charge for extended periods when not in use. This means that you can charge your battery before heading out to fly your RC aircraft or drive your RC vehicle, and it will still have enough power to operate.

    Additionally, NiMH batteries are environmentally friendly as they do not contain toxic metals like lead or cadmium, making them safe to dispose of and recycle.

Disadvantages of NiMH Batteries

    One of the significant disadvantages of NiMH batteries is their voltage drop-off as they discharge. This means that the voltage output of the battery decreases as it is used, resulting in a decrease in the performance of your RC vehicle or aircraft. To counteract this, it is recommended to use a battery with a higher capacity or use multiple batteries in parallel to maintain a consistent voltage output.

    Another disadvantage is their sensitivity to overcharging and over-discharging, which can lead to reduced battery life and performance. To prevent this, it is recommended to use a charger specifically designed for NiMH batteries and to monitor the battery's voltage levels regularly.

Optimizing Performance of NiMH Batteries

    To get the most out of your RC receiver NiMH battery, there are several steps you can take to optimize its performance. Here are a few tips:

Charge your battery before use and ensure it is fully charged.

Avoid overcharging or over-discharging your battery.

Choose battery charger specifically for NiMH batteries.

Put your batteries in a cool and dry place when it is not in using.

Choose battery with a higher capacity or use multiple batteries in parallel to maintain a consistent voltage output.

Monitor the battery's voltage levels regularly to ensure it is operating within safe limits.

Discharge your battery fully before recharging to prevent memory effect.
