Youme 4S Lipo Battery 14.8V 6500mAh 80C (2-Pack) - Reliable RC Power

In this review of the Youme 4S Lipo Battery 6500mAh, the bottom line is simple: it is a practical, high-discharge battery pack best suited for hobby RC drivers who need sustained power for heavy models. The biggest reason to buy is the combination of an 80C discharge rating and 6500mAh capacity that delivers steady high-current output and long run times for large trucks, crawlers, and multirotors. The two-pack format also makes it a convenient choice for frequent flyers or racers who rotate packs between sessions.

Key Features

• Capacity and Voltage: The 6500mAh at 14.8V provides extended run time for large RC trucks and aircraft, keeping sessions longer between charges.
• High Discharge: The 80C continuous discharge rate supplies strong burst and sustained power for heavy-load applications and higher top speeds.
• Built-in Protection: The pack includes internal protections and clear voltage guidance to avoid overcharge above 4.2V and over-discharge below 3.2V, improving safety during use.
• Pack Dimensions: At about 155 x 50 x 38mm, the battery fits many large-scale RC models when voltage and plug type match, making it versatile across brands.
• Certifications: CE, ROHS, MSDS, and UN38.3 certifications indicate the battery meets common shipping and safety standards for hobby LiPo packs.

Who It's For

This battery set is aimed at hobbyists running 1/8 to 1/5 scale electric RC trucks, truggies, and large multirotors that accept a 14.8V 4S pack and a TR discharge connector. Riders who want longer single-run times and the ability to deliver high current for demanding loads will appreciate the 80C rating and 6500mAh capacity.

People who should look elsewhere include users of electric mobility devices and smaller-scale models that require different voltages or connectors. Also note that some chassis like specific MAXX battery trays may require slight fitting adjustments or adapters due to snug tolerances.

Pros & Cons
