Interested in buying a new battery for your RC Car, or speeding up charge times with a new charger? This short guide aims to help.

Batteries

What battery does my car have?

The majority of batteries will have a sticker or some printed markings upon them, describing what type or technology they use.

  • Ni-Cd : Nickel Cadmium. Rechargeable, comparatively environmentally unfriendly and suffer from memory effect.
  • NiMH : Nickel Metal Hydride. Robustly rechargeable (can be topped off) and easy to maintain.
  • LiPo : Lithium-ion polymer. Higher energy density, lighter weights, consistent powerful discharge, shorter lifespan (than NiMH) more volatile than other solutions and require intelligent chargers.

Generally most low-end models will come with an inexpensive NiMH battery. Higher end models (especially those that are LiPo ready) often do not come with batteries and chargers at all, allowing the customer to either re-use their existing hardware, or purchase items specifically for their needs.

What is this battery connector?

There are a variety of battery connectors on the market, each suited to a different application, here are some of the more popular ones:

Tamiya Connector
Deans/T Connector
XT60 Connector
Traxxas ID Connector
JST RCY Connector
Balance Connector

How do I choose the right Battery for my car?

Now that we have an understanding of some of the basics, we can select the right battery. On a simple level, this boils down to a few variables: cost, connector, compatibility and dimensions.

Cost

If a battery has been included with the model, it is often selected by the manufacturer for a balance of performance, weight and production cost. Yet in ownership, many enthusiasts will want to buy batteries for their own financial needs. Several smaller capacity batteries are often cheaper, giving you the same combined runtime of a larger capacity battery whilst avoiding its much higher price and (often) additional weight.

Connector Type

Check which connector type your ESC or current battery shipped with, use our guide below to assist in identifying it.

ESC Compatibility

Further to this, check that your ESC is actually compatible with the new battery. Not just in the case of switching chemistries (from say NiMh to LiPo) but also when selecting a battery with more cells (eg a 4S LiPo from a standard 2S). This information can be found from the manufacturer or within the instruction booklet of your model.

Physical Restrictions

The obvious limit to fitting a battery in your model are the dimensions of the battery tray. Many models offer a clamp-style setup that can be shimmed,to increase its effective capacity. Some users do away with the battery tray altogether and employ velcro straps to secure the battery to the chassis.

Also worth mentioning is the weight of the battery as fitting a larger, heavier battery (than that specified by the manufacturer) will alter the performance and handling characteristics of the model, shifting its centre of gravity.


Battery Chargers

Its all very well buying high capacity batteries to extend your runtime, but if you are still using your bundled charger you are going to have a wait a day before you can race again! An intelligent charger can make all the difference, getting you back out driving in a fraction of the time and also ensuring your batteries are properly cared for.

Why is my battery charger so slow?

If you are on a limited budget, you are likely to be stuck with a trickle charger with a low output. For instance the traditional 'tamiya' style twin-pin connector (pictured below) that comes bundled with many of our models. With their 9.5v 330mA output, ‘fully charging’ a 7.2V 3300mAh battery would take 10 hours (dividing the capacity by the chargers output). As such these chargers are often referred to as 'overnight' ones. This isn’t ideal and as such we recommend you purchase a smart charger.

Which charger is the best one for me?

Smart chargers will typically come with a selection of connecting leads, balance boards and other accessories enabling them to be used with many different types of battery. If you intend to use LiPo batteries they are a no-brainer. Typically the higher-end smart chargers will be able to balance, discharge and storage charge batteries, essential functions for both caring and prolonging the life of your batteries.

This popular Overlander charger has a maximum fast charge output of 7A with support for 6cell LiPo and 8cell NiMH batteries. In comparison this could easily charge a 3300mAh battery in less than an hour. Its worth noting that regularly ‘fast’ charging batteries at high voltages will shorten their life.

Traxxas iD batteries are best charged with their EZ-Peak chargers such as the one above. This foolproof charger is designed to be used with the newer system with integrated balance cables, is compatible with both LiPo and NiMh cells and can safely charge at one button press.

I don’t have the right cable

Additional charge cable adapters are available to ‘future proof’ a smart charger against future plug innovations. Note that such cables are designed for charging only and are generally not intended to be used as a battery adapter for powering your car.


How should I look after my batteries?

To get the best performance and life out of your batteries, you need to treat them right.

Alkaline batteries commonly used to power transmitters are quite hardy, but we always recommend removing them from your controller if you do not intend to use the device for a long period.

NiMh batteries are also robust but can be damaged by overcharging so investing in a quality monitoring charger is wise. There is no need to fully discharge and recharge them and they should be stored in a cool location.

LiPo batteries are more sensitive and thus precautions should be taken when handling and charging them. A high quality charger that utilises the balance lead and reduces its current when the peak cell voltage is reached is recommended. Whilst LiPo batteries can be charged at high rates, the safest rate is 1C, literally one times the capacity of the battery in amps. For example a 3000mAh battery should ideally be charged at 3Amps.

Avoid leaving a charging LiPo battery unattended and store them in LiPo safe bags when not in use. LiPo batteries should be stored at 3.8v per cell (down from 4.2v) to maximise their life, many chargers offer a ‘storage’ charge function to achieve this.

A tool like this Emax Digital Battery Capacity Checker is perfect for checking the charge and also the balance of cells within LiPo batteries.
