If you need batteries for a new RadioMaster Pocket or want to replace an aging transmitter battery, this two-cell RadioMaster 18650 battery set is the straightforward option. It includes two rechargeable 3200mAh cells—the exact quantity required by the Pocket.
RadioMaster also lists these batteries as compatible with the Boxer, TX16S MKII, TX12 MKII and MT12. Each cell is rated at 3.7V, and the pair supplies 7.4V nominal voltage when installed. Because the cells operate in series, the usable capacity is 3200mAh, not 6400mAh. The total nominal energy of the pair is approximately 23.7Wh.
Independent Test and User Experience
In an independent capacity test, the RadioMaster 3200mAh cell delivered approximately 3058mAh under a 2A discharge load and weighed 46.2g. That result is reasonably close to the stated capacity and makes the battery well suited to the relatively low current draw of a radio transmitter.
For the Boxer, an independent review estimated around six hours of operation from two 3000mAh cells while transmitting at 1W with the screen backlight off. The exact runtime of this 3200mAh pair will depend on RF power, screen brightness, external modules and radio settings, but it should comfortably support typical flying sessions.
Verified RadioMaster customer feedback also reports normal charging and discharging in the Pocket, with runtime exceeding the owner’s initial expectations. This is useful real-user evidence.
Surface radio users who prefer replaceable rechargeable cells
RadioMaster states that the Pocket requires two 18650 cells and supports built-in USB-C charging. Batteries are not included with the standard radio, making this two-cell pack a logical add-on purchase.
Why Choose the RadioMaster Pair Instead of Generic 18650 Cells?
Generic 18650 batteries vary in capacity, chemistry, physical dimensions and terminal construction. Community discussions show that Boxer users are often uncertain about cell type, top style and charging compatibility; some generic cells work correctly, while others can have unreliable contact or fit problems.
This RadioMaster pair removes much of that uncertainty by providing:
● The correct two-cell quantity
● Published compatibility with the listed RadioMaster radios
● Matching cell capacity and specifications
● High capacity for transmitter use
● A simpler purchase for first-time RadioMaster owners
For customers already buying a Pocket or Boxer, choosing the matched pair is generally more convenient than sourcing and verifying two unrelated cells separately.
