RADIOMASTER SoloGood 7.4V 6200mAh Lipo Battery - Long Run Time

In this review the RADIOMASTER SoloGood 7.4V 6200mAh Lipo battery is assessed for pilots and hobbyists who use RadioMaster BOXER or TX16S transmitters. The bottom line: this pack delivers substantially longer run times and flexible charging options, so anyone tired of swapping cells mid-session will appreciate its 6200mAh capacity and compatibility. The review focuses on real-world fit, charging convenience and overall battery quality as reported by users who needed reliable transmitter power for extended flying or field use.

Key Features

• Large capacity: The 6200mAh capacity provides notably longer operating time, allowing sessions over three hours between charges for typical transmitter use.
• Dual charging options: You can charge via an XT30 connector with a capable charger or use the radio's USB-C charging input for onboard convenience.
• Designed fit: The pack is made to fit the RadioMaster BOXER and TX16S series radios, so users report a secure, no-modifications fit.
• Safer chemistry: Being a LIPO battery, it benefits from established charge/discharge characteristics that hobbyists expect when managed with proper chargers.
• Modest charge current: The pack accepts up to 2A charge current, which balances reasonable recharge time with battery longevity when used properly.

Who It's For

This battery is for RadioMaster BOXER and TX16S owners who want a single pack that extends transmitter runtime without added adapters. Field pilots, FPV racers and multiday event users will value the long idle life and the reported reliability of the pack when matched with the specified radios.

It is less suited to users who demand ultra-fast recharge or who need higher continuous discharge beyond standard transmitter loads; for those users a different chemistry or higher charge-rate pack may be more appropriate. Also, buyers who prefer battery types other than LIPO should look elsewhere.

Pros & Cons

Pros

• Long battery life that typically exceeds three hours in transmitters, reducing downtime between sessions.
• Works with both XT30 charging and the radio's USB-C input, offering flexible charge workflows in the field.
• Customers report a reliable, exact fit in RadioMaster BOXER and TX16S radios, eliminating fitment issues.

Cons

• Maximum 2A charge current means recharging can be slower than high-rate packs if a fast turnaround is needed.
