7.4V 1750mAh SBR-28Li Battery 2-Pack - Extended Run for Yaesu

In this review of the 7.4V 1750mAh SBR-28Li 2-pack from ROWSHEP, the bottom line is straightforward: this pair of replacement batteries is for owners of Yaesu FT-4 series radios who need significantly longer run time without upgrading the radio. Tested in real-world handheld use, the packs deliver steady power and predictable voltage, and the higher 1750mAh capacity is the single biggest reason to pick these over older lower-capacity replacements. For anyone whose work or hobby depends on reliable two-way communication, these batteries restore portable uptime with a familiar fit and charge behavior.

Key Features

• High capacity: The 1750mAh rating delivers extended operation compared with many stock cells, which translates to fewer mid-shift battery swaps.
• Stable voltage: Built with lithium-ion cell technology to provide consistent 7.4V output for reliable radio performance under load.
• Compact size: The slim 3.11 in x 2.03 in x 0.57 in footprint preserves the radio's balance and pocketability while adding capacity.
• Dual pack convenience: Two rechargeable packs in the box make it easy to keep one spare charged for continuous use during long outings or shifts.
• Warranty support: The included 24-month warranty and customer service offer peace of mind for everyday use and light professional applications.

Who It's For

The 2-pack is aimed at amateur radio users, field technicians, security staff, and outdoor enthusiasts who own Yaesu FT-4VE, FT-4VR, FT-4VX, FT-4XE, or FT-4XR radios and want longer operating time without changing chargers or accessories. It is especially useful for users who need a spare battery ready for extended events or back-to-back shifts.

Those who should look elsewhere include operators seeking batteries with radically higher capacity or integrated quick-charge circuits; this pack focuses on compatibility and reliable Li-ion chemistry rather than ultra-high-capacity cells or added electronics.
