Overview

The BP-IC307 is a 5,000mAh (36Wh) extended life battery pack for your Icom handheld. That's 2.7x the stock BP-272, and 1.6x the BP-307. Charge it over USB-C with PPS fast charging, swap the cells yourself when they eventually wear out, and get back on the air.

Built by hand in Greeley, Colorado. Made in USA.

Belt Clip Notice

This battery uses a Yaesu-style belt clip that secures from inside the battery housing. It does not support the stock Icom snap-in belt clip mechanism. This is a limitation of 3D-printed ASA plastic, which cannot reliably handle the repeated stress of the Icom clip-on/clip-off design without risking wear or breakage over time. The pack uses the same design as the Yaesu batteries, which is screwed on.

Charging Notes:

Not all USB-C cables are created equal. If charging doesn't start, try a different cable. USB-A to USB-C cables are the most universally reliable. PPS-capable chargers will negotiate the optimal charge rate automatically.

Recommended Charger:

Any USB-C charger rated 15W or higher will charge the battery at full speed. Lower-wattage chargers will still work — they'll just charge slower. PPS (Programmable Power Supply) chargers will automatically negotiate the optimal charge rate but are not required. A USB-A to USB-C cable with a standard USB-A wall adapter also works and is the most universally reliable option.

Charging Indicator:

• Red + Blue(May appear purple): Charging
• Red only: Fully charged
• Blue only: Slow charge
• Red flashing: Cable or charger issue — swap the cable

User-Serviceable Cells:

The BP-IC307L is designed for long-term ownership. When cell capacity eventually degrades, you can open the pack and replace the Samsung 50E 21700 cells yourself. No need to buy a whole new battery.
