The Ultimate Yaesu FT-530 Battery Solution.

If you're a fan of the Yaesu FT-530 like I am you probably already know that they are unbelievable battery hogs. Constantly burning up and rebuilding expensive battery packs for these radios is a royal pain in the ass. I believe I have found a solution to this nightmare. I now have two 12V 2500 mAh packs and one 7.2V 2500 mAh nickle-metalhydride packs with the highest quality cells available, the Sanyo ENELOOP XX Pro. These batteries are the best I have ever used. They claim to hold their 80% charge for TWO YEARS. They also claim these batteries can be cycled 1500 times. Though I haven't tested them myself, many reviews can be found on the internet.

So here is what you'll need.

1. First, a battery case. This can be the FBA-12. Either the 6-cell or the 10-cell case will work. These are readily available on e-bay.

2. Second, you need a suitable charger. The Omin-Pulse Smartcharger, $49.95 is available from several places but I bought mine from Batteries America. The instructions and charging details are available there so I won't bother to reprint the them here.

3. Third, you need the Yaesu FT-530 Bottom Cover. This is how you will interface your battery pack with the charger. This eliminates having to remove the batteries from the packs every time you want to charge them. The Yaesu part number is #R3807220B and it costs a whole $5.78 from Yaesu, and at this time it is IN STOCK.

You need to very carefully solder some leads to the base plate without melting the plastic. Pay attention to the polarity. Connect the other end of the leads to the charger.

Load your AA batteries into your case. I highly recommend a few drops of super glue on the case to make sure it doesn't come apart if you drop it. You can always take it apart again if you need to change the cells down the road.

Now, slide the pack on to the base plate just as you would attach it to your radio.

IMPORTANT. Wrap the Velcro thermal resister around the pack before powering up the charger.

Using the adjustment dial, set your charge rate according to the meter. For example, I charge my 2500 mAh packs at 250 mAh to 500 mAh The minimum is 250 (1/10 the capacity for Ni-Mh) and charging at higher rates increases heat. There is no need to "rapid" charge these batteries at 1 amp or higher though if you must, you can do it safely with this charger.

Now you have the best of both worlds. Instead of choosing between a high-voltage or a high capacity pack you can have a high-voltage / high capacity pack of 12V at 2500 mAh! You can buy and experiment with many different kinds of AA batteries and you won't have to rebuild your old. battery packs. Enjoy!
