Product Description

• Large Capacity Upgrade for Longer Playtime & Stable Power
• Constructed with high-quality 18650 power lithium cells at rated 7.4V, various capacity options greatly extend single-session playtime compared with original low-capacity batteries. High-rate discharge delivers instant throttle response and consistent power output during off-road crawling and high-speed racing, eliminating sudden power loss and optimizing your driving experience. Thick insulated outer shell resists impact and scratches for long outdoor service life.
• Multi-layer Built-in Protection for Explosion-proof Safety
• Each battery is equipped with a dedicated BMS circuit board with four core safety protections: over-charge cut-off, over-discharge cut-off, short-circuit lockout and over-current protection. It automatically cuts power when voltage exceeds safe limits during charging or usage, preventing swelling, fire and other hazards. Excellent cell consistency supports hundreds of charge-discharge cycles for lower long-term cost.
• Full Range Plug Options for Perfect Device Matching
• Comprehensive plug choices cover all mainstream model connectors:
  SM-2P/SM-3P/SM-4P, T-Connector, XT30, XT60, 5500 Plug, Large Tamiya, Small Tamiya, EL-2P, JST Plug.
• Two SM wiring versions are pre-marked clearly: Version 1 (Pin 1: Black Wire = Negative); Version 2 (Pin 1: Red Wire = Positive). Red wire always stands for positive pole while black for negative pole. You can check your original wire sequence before purchase for plug-and-play replacement with no wiring modification needed. Exact dimension data of XT30 & XT60 plugs are listed for precise port verification.
• Multi-scenario Compatibility for High Cost Performance
• This 7.4V battery works with nearly all electric toys running at 7.4V with matching plugs:
  All types of RC vehicles (4WD high-speed cars, crawlers, stunt cars, engineering trucks, gel blaster cars, transformable cars), bubble blasters, smart robots, portable wireless speakers, etc. One single battery fits multiple devices for outstanding value.
• Convenient Charging Solution for Recyclable Use
• Buy 2 batteries and get a free dedicated 7.4V USB charging cable, compatible with phone adapters, power banks and laptop USB ports. Built-in smart chips automatically stop charging once full, with indicator lights showing charging status for easy operation. The battery supports repeated recharging for eco-friendly long-term use.

Safety User Guidelines

• Fully charge the battery before first use. Only use the matched dedicated 7.4V charger; never use incompatible chargers.
• Never short-circuit positive and negative terminals. Avoid heavy compression or piercing the battery shell with sharp objects.
• Recharge promptly once power drops noticeably. Deep over-discharge will cause permanent irreversible cell damage.
• Charge in well-ventilated open areas away from flammable materials like fabric and paper. Unplug the charger right after charging completes.
• Stop using and dispose properly if the battery swells, cracks or leaks. Do not reuse defective batteries.

After-sales Policy 

• Warranty does not cover damage caused by self-selected wrong plugs, improper over-charge/over-discharge and artificial breakage. Lithium batteries are classified as special shipping goods; you may check local courier policies in advance.
