Product Description
- Large Capacity for Extended Playtime, Ideal Upgrade

No more frequent power cuts during outdoor activities. High-rate discharge design ensures consistent power output for climbing and high-speed racing, greatly improving your driving experience.
- Multi-layer Protection Circuit & Explosion-proof Structure
- Equipped with a dedicated battery management system (BMS) providing 4-fold protection: over-charge, over-discharge, short-circuit and over-current prevention. Effectively avoids risks like cell swelling and short-circuit fire. Thickened outer insulation wrapping enhances durability and explosion resistance, making it safe enough for kids’ daily toy use.
- OEM SM3P Plug, Seamless Fit for MN RC Models
- Factory-fitted SM3P 3-pin male connector matches the original port of MN MN82 and MN78 RC crawlers exactly. Direct plug-in replacement requires no wiring modification, keeping your vehicle intact. The buckle-style plug stays firmly connected even on bumpy off-road terrain for stable power supply.
- Versatile Compatibility for Multiple Devices
- Besides MN series RC off-road vehicles, this 7.4V 18650 battery works perfectly with bubble machines and other electric toys that use the same SM3P port. One battery serves multiple devices for outstanding cost performance.
