Fast electric rc cars – To know about RC Battery

When we talk about fast electric rc car speed, one of thing in our mind is battery. Battery is one of important part of fast electric rc car. It function is to generate a power to fast electric rc car, without that the fast electric rc car won’t be run. Battery also is one of the part which ensure how fast and how long your rc car can run especially to someone who have plan to enter in rc car race or competition.
You can find a few type of battery in the market today, and of course it will make us confuse to choose which are the best to be used for your fast electric rc car.
There are two type of battery which is commonly use by fast electric rc car community today :
1) Nickel Cadmium ( Ni-Cd )
2) Nickel Metal Hydride ( Ni-Mh )

Nickel Cadmium Batteries.( Ni-Cd )
This type of battery had already been used since long time ago. You can choose from a various capacity such as 1400mAh, 1500mAh, 1700mAh, 2000mAh, 2400mAh and 3000mAh. In term of cost, this type of battery is cheaper and lowers capacity in the market. The most popular capacity which commonly used are 1500mAh and 2400mAh, this is because this range of capacity are easily to get.
Battery 1500mAh is sold in one pack ( standard packing ), it contain 6 pcs battery which had already soldered and packed in plastic, it’s has become a easiest battery to used, maintained and stored. This battery is the best choice and suitable for beginner who are used stock motor for their electric rc car and remember, this battery is not suitable to used at fast electric rc cars which is assemble with modified motor.
Battery 2400mAh is more expensive compared to battery 1500mAh, and it’s comes or sole separately (piece by piece) and need to solder with battery bars. Advantage of this battery are, it has ability to generate your fast electric rc car run faster and longer running time than battery pack with 1500mAh capacity.

Nickel Metal Hydride batteries ( Ni-Mh )
This is the battery which was created with latest technology and was created since 1999 and compliant to environment expect. This battery can easily recycle compared to nickel cadmium which is difficult to recycle.
In term of performance this type of battery can perform much better than nickel cadmium. Minimum capacity for this type of battery available in the market is 3000mAh but you can find a higher capacity today and it’s become the most popular because it has ability to generate faster in speed and longer run time compared to nickel cadmium.
This type of battery are specially created and build for advance or professional rc community and suitable for fast electric rc cars, therefore it’s normally comes or sole separately in the market and need to soldered. In term of price, of course it’s expensive.

Fast electric rc cars – Electronic speed controller ( ESC )

Every of fast electric rc car which power by electric ( EP ) require an electronic speed controller ( ESC ), purpose of this equipment are to control electric current from battery to motor and low or high speed of your fast electric rc car. With an efficient of it control system ESC also able:
-To avoid circuit from burn.
-To control or avoid leak current during transfer from battery to motor.
-To stabilize current during speeding.
-To use with faster ( high rpm ) motor.
(Turn-The lower a number of turn, the faster a rpm of each motor)
Ability of each ESC are measure from it ampere and level of voltage of each ESC can received. Each of ESC able to absorb current from 4 to 8 volt and it depend on number of ampere and measure in unit ohm.
ESC are build with it own function such as set-up and mode. This is to ensure desired speed level of each your fast electric rc car. You don’t have to worry about setting of your ESC because most of ESC will provided with set up work guide or software in the package to guide you. Normally this package can be found in expensive ESC unit like LRP, GM, Novak, Nosram and many more.
Beside that most of ESC also comes with ‘heatsink’. Heatsink work as a cooler to your ESC and ensure that your ESC work with normal temperature. Extremely temperature will give a negative impact and effect to your ESC performance. Temperature of your ESC normally will increase when your fast electric rc car run at low speed. The phenomena may relate to gear ratio you had chose, therefore you have to careful to choose a suit gear ratio for your fast electric rc car.
If you have plan to buy a ESC, you are advised to ask someone who have good experience in this field or ask for recommendation from you nearby hobby shop.
This are important to avoid a wrong choice and waste your money.
