Back to Batteries

Nicely built. Fit to the radio is good. The instructions need to be updated on the very first part due to a change in manufacturing. Extends the battery life tremendously. Have already recommended it to friends.

FT-5 battery kit

Bought a couple for my Dad and I to do as a project together. Watch the linked video, it makes the steps go smooth. Wasn’t overwhelming or too difficult. The end product is great. After a full charge, I left the radio on with APRS running tx every 60 min and the pack got me 20 hours. No complaints here. In addition, customer service is outstanding. Communication was fast and to the point.

Worth the wait

I've been using this battery pack for several weeks now and it's fantastic! Lasts for days and charges quickly with a high current charger.
Here's the caveat, I bought it as a kit and it was a bit intimidating, but I was up for a challenge and have pretty good soldering skills. It was difficult and I ran into a few issues that were promptly addressed by W0AEZ.
Assembled and working great, but I would highly recommend spending the money and buying already assembled.

A fun kit build and works great on my FT5D

Fun kit, but you're not going to build this with a clumsy fat soldering iron. It requires a bit of finesse and patience. Double and triple check your wiring and battery orientation before putting the batteries in it. I referred to the pdf on the website as well as a YouTube video. The 3D printed parts are very well designed and the final fit it fine. A tight mate with my FT5D. The 'finish' of the plastic prints is average. You can tell it's a 3D print. The battery capacity is fantastic. I can leave my radio monitoring on a local emergency service frequency for 36 hours or so before the radio objects. Charging is easy. The 2 lithium cells are Samsung INR21700-50E, well made and good review.

Finally, customer support from W0AEZ is top notch. He obviously cares about his product and reputation. This is what ham radio is all about.

Great Battery

This battery lasted me over 24 hours in the field. This combined with the USB-C charge port is the perfect battery.

BP-K75L v2 is a game changer for D74 / D75 users

I have been a user of the D74 / D75 for several years now. They are both great radios with one major design flaw - their batteries.

I used to belong to a RACES organiztion and frequently participated in excercises requiring extensive use of my HT. I always wanted to use the D75 but was unable to do so simply because of its battery performance. Although I could have purchased additional Kenwood batteries these batteries are very costly and would have required several of them to last a full day of heavy use. Alas, I had to purchase a Chinese radio that was much less capable than than D75 but had great battery performance.

The BP-K75L v2 has changed all that. Although it adds a little bulk and weight to the D75, it is no bulkier or heavier than an ID-52 with the high capacity batter pack. It also performs just as well and maby even better.

If you are a D74 / D75 user get this batter pack. It is well made and has great customer service!

FT5 Power On with BP-Y14Lv7

Awesome power life!!! Easy to recharge via USB-C power port without removing battery from HT. Only suggestion would be to design a better, easier to release tabs from HT as it is a little difficult.

Great Upgrade

This makes the FT3D useful for more than 5-6 hrs. I have been able to receive for about 48 hours.
Highly recommend for anyone wanting to use their Yaesu handheld for more than a few hours.

My review of the BP-K75L

This battery is all that it said it would be. It lasts me two days of use before I need to charge it. I have all ready purchased the one for my FT-5DR. I highly recommend this battery for anyone looking for using the HT for extended time.

Nice battery

The battery fitment is nice and tight. Support when an issue was found has been good. I am still waiting for the replacement board but the communications from seller are positive

Great mini power bank. I use it with my QDX for a mini digital station. and can go several hours at 9V. Even use it to quick charge my phone.

Long operation with TH-D75

I did some tests, side by side with the original battery and W0AEZ's battery. In all my tests, this battery performed 3x better than original. I love this battery when I go hiking as I trust it for APRS and voice for around 12h. APRS only is 18h. Thank you for making it!

Real nice assortment!

I don't think I have anything that uses TNC connectors anymore, but I did have an old wireless router that did. The rest I use almost daily for one thing or another!

Good Capacity---Finally for my FT3 power hog!

Though I'm not nuts about the orange one I got (only one available at the time) I have to say it is very useful. It still fits in the charger base though without the radio. I can also use the USB C connection which is a handy alternative. It seems to be very rugged with the 3d printed case very rugged. Good Piece of equipment!

I forgot to turn the radio off!

I was monitoring a couple of local repeaters and got distracted. The screen timed out and I went to bed. Halfway through the next day I went to turn it on and found it already on and the battery indicator as full. The old 1800 mha battery will die after a couple of hours. Cool beans!!!
