Li-ion Battery 7.4V 2000mAh with Dean-Style T Plug 2S Rechargeable RC Battery Fit for WLtoys 4WD High Speed RC Cars and Most 1/10, 1/12, 1/16 Scale RC Cars Trucks including 1TO2 USB Charger

Product Overview

The battery is a 7.4V 2000mAh Li‑ion power source designed for use in radio‑controlled vehicles. It features a Dean‑Style T plug in a 2‑cell (2S) configuration, allowing it to be mounted directly into compatible RC car or truck chassis. The rechargeable pack is paired with a 1TO2 USB charger that supplies power through a standard USB interface.

Key Features

• Voltage and Capacity: 7.4 V, 2000 mAh Li‑ion battery.
• Connector: Dean‑Style T plug, 2‑S series configuration.
• Compatibility: Fits WLtoys 4WD high‑speed RC cars and most 1/10, 1/12, and 1/16 scale RC cars and trucks.
• Charger: Included 1TO2 USB charger.

Installation and Use

Installing the battery requires aligning the Dean‑Style T plug with the corresponding connector on the vehicle’s battery bay. The T shape of the plug provides a secure mechanical fit, reducing the likelihood of accidental disconnection during operation. Once inserted, the battery can be removed and recharged using the supplied USB charger.

The charger features a USB input, meaning it can be powered by any USB source such as a laptop, power bank, or wall adapter that supplies the appropriate voltage. The 1TO2 designation indicates that the charger can convert the single USB input into the 7.4 V output required by the 2‑S Li‑ion pack.

Performance Characteristics

At 7.4 V, the battery delivers a nominal voltage suitable for many small RC vehicles that require a two‑cell Li‑ion supply. The 2000 mAh capacity provides a moderate amount of stored energy, enabling several sessions of use before a recharge is needed. As a Li‑ion battery, it offers a relatively flat discharge curve, which helps maintain consistent voltage across typical operating ranges.

Recharging Procedure

To recharge, connect the USB charger to a power source and then attach the charger’s output to the battery’s Dean‑Style T plug. The charger will manage the voltage and current to safely bring the battery back to full charge. After recharging, disconnect the charger before inserting the battery into the vehicle again.

Safety Considerations

Li‑ion batteries should be handled with care. Avoid exposing the battery to extreme temperatures, physical shock, or punctures. Store the battery in a dry, cool environment when not in use. The charger’s USB interface limits the input voltage, but users should verify that the USB source supplies a stable voltage compatible with the charger’s specifications.

Product Packaging

The battery arrives in a sealed package that includes the Li‑ion pack, Dean‑Style T plug, and 1TO2 USB charger. No additional accessories are listed. The packaging is designed to protect the components during shipping and handling.

Compatibility Notes

While the battery is marketed as fitting WLtoys 4WD high‑speed RC cars, it also supports most RC cars and trucks in the 1/10, 1/12, and 1/16 scale ranges. This broad compatibility arises from the common use of the Dean‑Style T plug in many hobbyist vehicles. However, exact fitment may vary with specific models, so users should confirm connector dimensions before purchase.

Maintenance and Longevity

Maintaining the battery’s performance involves periodic recharging and storage in a partially charged state when not used for extended periods. The battery’s lifespan depends on the number of charge cycles, but as a Li‑ion pack, it generally supports several hundred cycles before capacity diminishes noticeably. Proper charging practices help preserve longevity.

Summary

In summary, the 7.4V 2000mAh Li‑ion battery with Dean‑Style T plug is a rechargeable power solution for a variety of small RC cars and trucks. Its 2‑S configuration and included USB charger provide a convenient way to keep the vehicle operational between sessions. The battery’s design aligns with common hobbyist standards, making it a straightforward addition for users looking to upgrade or replace the power source in compatible models.
