HPI 3300mAh NiMH 7.2v Racing Pack With Tamiya Connector

I’ve been getting quite a few emails recently from newcomers who are confused about buying batteries for theirĀ  RC Cars, particularly when looking at used Radio Controlled Cars. Many ready to run cars come with suitable (or at least OK) 7.2v batteries, but most kit based models and in the majority of case, second hand rc cars don’t come with a battery. For someone who’s new to the hobby, choosing the right battery can be a little daunting, but it’s really quite simple. You just need to remember two or three things and once you’ve bought you’re first couple of batteries, you’ll be far more clued up on how they perform and what you can get for your money. But to start you off, and hopefully answer a few of the more common questions, so here goes:

  1. NiMH (Nickle Metal Hydride) Batteries are the best choice for beginners. They have less memory effect than NiCd and aren’t as volatile as LiPo batteries. Plus you can charge them with pretty much any budget RC car charger on the market.
  2. Battery Capacity is indicated on a battery in the form of mAh, or Milliamps Per Hour. ANY capacity battery will work with ANY radio controlled car. The only thing that gets affected is the length of time you can run the car for and the amount of punch or acceleration the car has. Simply speaking a 5000mAh battery will in run a car for twice the length of time that a 2500mAh battery will. In short, buy the highest capacity you can afford. The larger the mAh figure on the battery, the higher the capacity.
  3. 7.2V is the standard voltage that the majority of beginners cars will run at. Some will take 8.4V batteries as an upgrade option, but check before buying to ensure your car can accommodate the larger physical size of the battery.
  4. Check the connector your car uses. Most RC cars come with an industry standard Tamiya style white plug, but some such as Traxxas RC Cars & Trucks, come with their own proprietary connectors, so make sure the battery pack you’re buying has the right one for your car, buggy or truck.
  5. Stick to a well respected brand where possible. You don’t have to stick to the same brand as your car, but look for the most popular sellers on Ebay or at your local model shop. We’ve had excellent results with Vapex Tech & Ansmann, as well as ModelSport UK own brand.

Don’t forget, if you have any questions, or indeed any tips of your own, please feel free to post them for your fellow readers in the comments below :)
