Dogcom 21700 Li-ion 5000mAh 2S1P 7.4V Radio

Dogcom 2S Transmitter Li-Ion Battery (XT60 & JST-XH) | RadioMaster TX16S & Boxer Compatible

Massive Energy Density. Unmatched Runtime. The Ultimate Li-Ion Radio Upgrade.

Never let a low-battery warning cut your flying session short. The Dogcom 2S Transmitter Li-Ion Battery is a premium, high-capacity lithium-ion power solution engineered specifically to fit perfectly inside modern, full-size FPV remote controllers. Designed with an optimized form factor, this pack slides seamlessly into the battery bays of the industry-leading RadioMaster TX16S and RadioMaster Boxer, providing hours of continuous operational runtime for high-output internal RF modules or power-hungry external ExpressLRS setups.

Built using Dogcom’s signature high-density, low-internal-resistance Lithium-Ion cells, this 7.4V transmitter pack yields incredible energy capacity relative to its weight. Unlike traditional LiPo packs, Li-Ion chemistry offers a remarkably stable shelf life, does not suffer from gas puffing, and delivers a highly predictable, linear voltage discharge curve. For maximum convenience, the battery features a dual-lead configuration: a heavy-duty XT60 connector for fast, easy charging using your standard charger, alongside a standard JST-XH balance plug that interfaces perfectly with your radio’s internal charging circuitry or power input.

Key Features

• High-Capacity Li-Ion Chemistry: Premium Lithium-Ion cells provide significantly longer runtimes and deeper discharge cycles than standard LiPo equivalents.

• RadioMaster Optimized Fit: Tailored to match the exact battery bay dimensions of the RadioMaster TX16S, Boxer, and similar full-size transmitters.

• Dual-Lead Convenience: Equipped with a dedicated XT60 plug for safe, high-speed charging on standard bench chargers, plus a standard balance lead for radio power.

• Ultra-Safe & Long-Lasting: Inherent Li-Ion stability ensures excellent lifecycle longevity with zero risk of cell swelling or puffing under normal radio operating conditions.

• Linear Voltage Curve: Maintains consistent output voltage over hours of active use, keeping your transmission signal strong from the first flight to the last.
