Blomiky 2 Pack 3.7V 800mAh Li-ion Rechargeable Battery SM 2P Plug with USB Charger for Double Sided RC Stunt Car Small RC Boat Tumbling Amphibious RC Car RC Truck/ C63 Battery and USB 2

Product Overview

These batteries are a pair of 3.7 V, 800 mAh lithium‑ion rechargeable units packaged together for use in small remote‑controlled vehicles. Each cell is designed with a standard 2‑pocket (2P) configuration and is compatible with the SM plug type commonly found on lightweight RC models.

Key Features

• Voltage and Capacity: 3.7 V nominal, 800 mAh per cell
• Pack Configuration: Two cells per pack, providing a dual‑battery setup in a single unit
• Recharging: Included USB charger allows direct recharging from a standard USB port or power adapter
• Connector: SM 2P plug format suitable for a range of small RC platforms
• Application: Engineered for double‑sided RC stunt cars, small RC boats, tumbling amphibious RC cars, RC trucks, and vehicles using the C63 battery standard

Compatibility

The batteries are intended for use in remote‑controlled models that require a 3.7 V supply. Their dimensions and connector type match the specifications for:

• Double‑sided RC stunt cars
• Small RC boats that demand a lightweight power source
• Tumbling amphibious RC cars that operate on a single 3.7 V battery
• RC trucks designed for single‑cell power delivery
• Models that accept the C63 battery format

Charging Instructions

Connect the provided USB charger to a USB‑enabled power source. The charger regulates the voltage to safely charge the two 3.7 V cells. When the charger indicator reaches full status, remove the batteries from the charger and install them in the compatible RC device.

Recharging Cycle and Longevity

Each 800 mAh cell can be fully recharged many times before capacity diminishes. The manufacturer does not specify an exact cycle life, but typical Li‑ion cells of this specification retain functional performance after several hundred charge cycles.

Safety Notes

All Li‑ion cells should be handled with care. Avoid discharging to extremely low levels and do not expose cells to extreme heat or direct flame. Use the supplied charger only; using an incompatible charger may damage the cells.

Storage Guidelines

When not in use, store the batteries in a cool, dry place. If the batteries will be stored for an extended period, it is advisable to keep them at a partial charge—roughly 50 %—to maintain health and prevent deep discharge.

Maintenance

Periodically check the charging cable and connector for wear or damage. Ensure that the USB port remains clean and that the connector fits snugly into the vehicle’s battery compartment to prevent accidental disconnection during operation.

What Comes in the Box

The package includes two 3.7 V, 800 mAh Li‑ion batteries, a USB charging cable with a standard USB connector on one end and the SM 2P plug on the other, and a brief user guide outlining charging and safety steps.

Summary

These dual‑cell batteries provide a reliable 3.7 V power source for a variety of small RC vehicles. The included USB charger offers convenient recharging from common USB outlets. The SM 2P connector is tailored for lightweight models that use the C63 battery format or similar setups. By following the provided charging and storage instructions, users can maintain the longevity and performance of the cells throughout their service life.
