LiPo Batteries
What do the numbers mean on a LiPo battery?
This is a common question for us so we thought we'd put a brief description to what each number means on a LiPo battery.
- 11.1v (Voltage) - Higher this number the faster your RC model will go, however, go too high and you'll risk burning out an electronic component like you motor or ESC.
- 5400mAh (Milliampere Hour) - This is the capacity of the battery. Think of this as a fuel tank in your real car, if you have a 50-litre tank it will last half as long as a 100-litre tank but of course, it won't make a difference to the performance.
- 35C (C Rating) - You multiply this number by the Ah (mAh/1000) to get the maximum amp draw you can put on the battery before you damage the battery. Please note, in most models, this rating isn't typically that important. However, in some high-powered models, you may need a higher C rating.

To get more run time, buy a battery with more mAh. You can think of the mAh as a fuel tank in a petrol car, upgrading from a 25L tank to a 50L tank will double your run time but you won't see any performance increase.
The run time also greatly depends on the amount of load on the motor. Just like your real car, if you're heavy on the accelerator you'll run out of fuel quicker. There's many other factors that will change the amount of load on your electronics such as:
- Wheel size, material, weight and tread pattern
- Gearing
- Driving style
- Terrain
- Drivetrain efficiency
- Aerodynamics
NiMH and LiPo are types of batteries. If you want a high-performance setup, go LiPo. If you're not too fussed about speed NiMH would be the better option as they are safer and require less 'special attention'.
Also, it makes a lot of sense to get a LiPo battery if you have a brushless powered car and to get a NiMH battery if you have a brushed powered car.
To get more power, you simply buy a battery with more voltage. However, you need to ensure your vehicle and it's electronics can handle the extra power to avoid damage.
Typically you can find this information in your user's manual, if you're unsure just ask us - never guess!
It's not too uncommon that to install a battery with more voltage that you need to modify the RC car in someway, this may include installing a different motor gear, cooling fan and even change your driving style.
The charge time can be calculated by dividing the battery's mAh by the mA output of your charger.
For example, let's say we have a 7.4v 5,400mAh LiPo battery and we're charging it on the G.T Power B3 charger which has an output of 1.5A (1,500mAh) - Tip: the charger's output in A (amps) or mA (milliamps) will be per hour. The calculation will look like this: 5,400/1,500 = 3.6 hours (which is 3 hours and 36 minutes).
We list each battery's length, width and height in the specifications tab in its product page. It's your responsibility to measure your battery compartment to ensure proper fitment.

Some RC cars are classified as dangerous goods because they include a LiPo battery. You can tell an RC car is dangerous goods if it has a warning note like this one:
If you need your RC car sent by express post ensure it doesn't have this warning and you select the option during checkout.
