The kit allows for insane acceleration, higher top speeds, and longer run times, while still maintaining complete functionality of the two-speed transmission and reverse. The instant-on of electric power allows for greater control of the front end with a tap of the brakes or stab of the throttle. The brushless motor also provides brutal power, and the high-performance LiPo battery means first gear is not needed at all.

There are a variety of options for conversion kits, including the Losi kit, eBay kits, and the RC Monster kit. The Losi kit is reported to turn the truck into an intolerant wheelie monster, and is also difficult to find. The eBay kits are praised for their price and quality, but some have opted to make their own kits using sheet metal. The RC Monster kit is also an option, but it does not include an LST mount.

For those looking to keep the speed the same as the Mach engine, one user recommends the following:

  • Hobbyking 150A ESC
  • Turnigy Trackstar 1/8th Sensored Motor 1900Kv
  • Turnigy nano-tech 5000mah 4S 65~130C Lipo Pack
  • 5 Pairs of EC5 Connectors

Motor mounts

If you're looking for a cost-effective option, you can consider using a ready-made conversion kit, such as the Losi LST Electric Conversion Kit (LOSB0017). This kit is compatible with a range of Losi trucks, including the LST, LST2, LST XXL, Aftershock, and Mega Baja. It offers a straightforward way to convert your truck to brushless electric power, providing all the necessary hardware.

However, some users have noted that the Losi kit has limitations in terms of gearing options. As an alternative, you can explore motor mounts from companies like RC-Monster and TDR, which offer more gearing flexibility. RC-Monster, for instance, provides a range of products, including motor mounts, battery trays, and pinions, allowing you to customize your setup.

When choosing a motor mount, it's important to consider the size of your motor. For example, one user inquired about the compatibility of the Losi electric conversion kit with 36mm motors, as these were in short supply. It's worth checking the dimensions and compatibility of your chosen motor with the mount to ensure a proper fit.

Additionally, the placement of the battery and other components can impact your motor mount selection. In some cases, retaining the mechanical brakes and mechanical reverse may limit the space available in the front of the vehicle, influencing your overall setup design.

If you're handy and want to save some money, you can also consider creating your own motor mount. This DIY approach gives you complete control over the design and customization of your mount, but it requires careful planning and execution to ensure a secure and functional setup.

In conclusion, when converting your Losi LST to electric, carefully consider your motor mount options. Whether you choose a ready-made conversion kit, opt for third-party motor mounts, or fabricate your own, ensure that your setup aligns with your performance goals, budget, and the specific dimensions and requirements of your vehicle.

Batteries

When selecting batteries for your conversion project, you'll need to consider factors such as voltage, capacity, and discharge rate. Let's explore some options and guidelines to help you make an informed decision:

Lithium-Polymer (LiPo) Batteries:

LiPo batteries are a popular choice for high-performance RC vehicles due to their high energy density, lightweight, and ability to deliver high discharge rates. When converting your Losi LST to electric, you'll typically want to opt for a 4S (four-cell) LiPo battery setup. This configuration provides a balance between power and runtime, allowing you to match or exceed the speed of the nitro engine. For example, a 4S 5000mAh 65C-130C LiPo battery pack, such as the Turnigy nano-tech brand, can deliver ample power and capacity for your electric Losi LST.

Battery Voltage:

The voltage of your battery will directly impact the speed and power of your electric Losi LST. A higher voltage, such as a 4S setup (14.8 volts), will generally provide more speed and torque compared to a lower voltage configuration. If you're seeking even higher top speeds, you can consider upgrading to a 5S or 6S battery setup, which will increase the voltage and, consequently, the performance of your vehicle.

Battery Capacity:

Battery capacity is measured in milliampere-hours (mAh) and indicates how long your battery can power your vehicle before needing recharging. Higher capacity batteries, such as those in the 5000mAh range, will provide longer runtimes compared to lower capacity options. It's important to strike a balance between capacity and weight, as heavier batteries may impact the overall performance and handling of your Losi LST.

Discharge Rate (C-Rating):

The discharge rate, often denoted as the C-rating, indicates how quickly the battery can deliver its stored energy. A higher C-rating means the battery can provide more current, resulting in faster acceleration and higher top speeds. For example, a 4S 5000mAh 130C LiPo battery can deliver extremely high current, making it suitable for high-performance applications. Ensure that your chosen battery's C-rating matches the power requirements of your electric Losi LST setup.

When converting your Losi LST to electric, it's important to prioritize quality and compatibility. Opt for reputable battery brands known for their performance and safety, as lower-quality batteries may not provide the expected performance or may pose safety risks. Additionally, consider consulting online forums and resources specific to Losi LST conversion discussions, as other enthusiasts can provide valuable insights and recommendations based on their first-hand experiences.
