7.2V RC Battery Pack 3800mAh NiMH (2 Pack) - Fast Charge

In this review the GEILIENERGY 7.2V RC battery pack is evaluated for RC hobbyists who need a reliable, high-output NiMH replacement. The reviewer finds the 2 pack of 3800mAh Sub C cells best for racers and casual flyers who want a steady discharge and quicker turnaround between sessions thanks to the included smart charger with a standard Tamiya connector. The single biggest reason to buy is the combination of a high discharge capability and a high capacity that keeps models running longer while supporting rapid charging when you need to get back on the track.

Key Features

• High output: The Sub C NiMH cells deliver a 10C discharge rate so models get steady, high power for aggressive RC use.
• High capacity: The 3800mAh rating provides longer run times than typical NiCd packs, reducing how often you need to swap batteries during a session.
• Standard connector: The pack uses a standard Tamiya connector for wide compatibility and simple installation in many RC cars and trucks.
• Rapid charging: The included 7.2V smart charger supports faster charge cycles so downtime between runs is reduced.
• Stable discharge curve: NiMH chemistry offers a predictable voltage curve that helps maintain consistent speed and motor performance.

Who It's For

This pack is well suited for hobbyists who run 7.2V RC cars, trucks, tanks and boats that accept a Tamiya connector and can benefit from a high-discharge NiMH pack. Racers and weekend drivers who want higher top speed stability and a longer per-charge runtime will appreciate the 3800mAh capacity and 10C output.

Users who need the absolute longest possible runtime per charge or who require lithium-based weight and voltage advantages should look elsewhere; if your model specifically requires a different connector or a lower profile pack, confirm dimensions before buying.

Pros & Cons

Pros

• Good balance of capacity and discharge rate for sustained high-speed performance.
• Includes a smart charger and uses a standard Tamiya connector for easy compatibility.
• NiMH chemistry means no memory effect and convenient charging any time.

Cons

• Some users report mixed battery life compared with newer chemistries, so runtime expectations may vary.
