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.
