BP-K75L v2 | Complete | TH-D7X | 5Ah | USB-C Charging

Awesome Solution!

This is a great solution to a bad electronic energy consumption design, so many thanks for solve the Yaesu issue.
Answer... one or one and a half day of normal use, transmitting reasonably. One day since 6am to 8pm on scanning mode plus APRS. Radio in one memory plus APRS, two days.

Just a final solution on Yaesu devices!

Amazing customer service

Bought 3 of the 5ah batteries. After they had shipped got an email that something was wrong and he would be sending out the parts to fix. Super easy fix and great product AND product support

Great Battery!

It was once said that you could load the Henry rifle on Sunday & shoot it all week. This is the Henry rifle of batteries!

Tom Cain

Great

This is a "Pocket Powerhouse".
Can't beat the price also.

Larry Miller

Love the extra power

Having an extra edge with battery capacity, it really makes a difference. Hard to find something like this anywhere else.

Very impressed!

Great quality battery is big but the benefits are huge as the battery last for days instead of hours compared to my stock Yaesu battery.

Increase time

Definitely increases usable time with the battery. Great purchase.

Todd Hockert

The FT70 is a great transceiver with its only weakness being its battery life. The BP-Y24L eliminates this weakness with nearly double capacity and as a bonus, it adds charging capability by USB. Sollid build and good appearance.

Gary Garnett

The battery is better than the factory one.

Brad Newhouse

Good battery

Much better than the one that came with the radio. Longer time between charges.
