Types Of Batteries For Traxxas Slash

If you want to upgrade your Traxxas slash battery, you’re probably wondering which type will maximize your vehicle’s performance. There are a few different options on the market, each with its own set of benefits and drawbacks.

NiMH Batteries

NiMH batteries, or nickel-metal hydride batteries, are a popular choice for those who want a budget-friendly option. They’re also readily available and easy to find in hobby stores. Here are some key points to keep in mind when considering Nimh batteries:

  • They’re affordable and easy to find
  • They offer good power and runtime
  • They have a lower capacity compared to other types of batteries
  • They tend to be heavier, which can affect the vehicle’s handling and speed

Lipo Batteries

Lipo batteries, or lithium polymer batteries, are a newer technology compared to NiMH batteries. They have a higher energy density, which means they can store more energy in a smaller, lighter package. Here are some key points to keep in mind when considering lipo batteries:

  • They offer a higher capacity and runtime than Nimh batteries
  • They’re lighter and more compact, which can improve the vehicle’s handling and speed
  • They’re more expensive than NiMH batteries
  • They require special care and handling, as they’re more prone to catching fire or exploding if mishandled

Li-Ion Batteries

Li-ion batteries, or lithium-ion batteries, are similar to lipo batteries, but they have a different form factor and chemistry. They’re also becoming more popular in the RC hobby world. Here are some key points to keep in mind when considering li-ion batteries:

  • They’re lightweight and have a high energy density, which can improve the vehicle’s handling and speed
  • They offer a longer lifespan compared to other types of batteries
  • They can be more expensive than NiMH batteries
  • They require special handling, storage, and charging procedures

As you can see, each type of battery has its own set of benefits and drawbacks. When choosing a battery for your Traxxas slash, consider what kind of performance you’re looking for, as well as your budget and level of experience with handling RC batteries.

Longer Duration Of Use

A new battery can also help to extend the duration of use of your Traxxas slash. With a larger battery capacity, your car will be able to run for longer periods of time before needing to be recharged. This is especially useful if you’re planning on using your Traxxas slash for extended periods of time, or if you’re racing multiple heats.

  • A battery with a higher mah (milliampere-hour) rating can provide more energy and last longer between charges.

Overall, upgrading the battery of your Traxxas Slash can greatly enhance its performance. With improved speed, acceleration, and duration of use, you’ll be able to enjoy your remote control car even more.
