Li-ion Battery Pack for V3i, VX3, DFX, and XLT

You can spend $79.95 on White's heavy duty NiMH rechargeable battery pack or even $134.95 for the battery and charging stand OR you can build a new 3400mAh Li-ion battery pack that fits directly into your V3i, VX3, DFX, and XLT metal detectors for just under $75.00.

No soldering, sanding, or wiring. Just purchase the new battery pack, Li-ion batteries (3), and a Li-ion charger. The charger will also charge NiMH batteries in addition to Li-ion batteries.

1. The battery pack holder assembly. I purchased it on ebay from seller sn0wboarder. Go to ebays home page. Click on Advanced Search. Copy and paste sn0wboarder into the Sellers search box. It is shipped from the Ukraine and took 8 days to arrive. Tracking information was provided. $23.00 plus $7.00 shipping. $30.00 total. Sn0wboarder sells out fast so keep checking back.

The ebay seller for the battery pack holder assembly is also on Findmall Spectra V3/V3i/VX3 Forum under username romanchuksl.

2. Li-ion batteries. Three (3) are needed. I also purchased these on ebay. Panasonic NCR18650B Li-ion battery 3400mAh from ebay seller r-lsales. $21.75 for three batteries and free shipping. The batteries are wide button top, 69.19mm in length and 18.64mm diameter. They have the protected circuit built in. I would suggest NOT using unprotected batteries.


3. Battery charger. XTAR VC4 Battery Charger from ebay seller sportinggearunlimited. $25.99 with free shipping. Simple to use! Place the three batteries in the charger and plug it in...that's it. You can monitor individual cell voltages and mAh at the press of a button if desired.


Total cost: $74.74.

Copy and paste the seller names above in red and do an advanced search on ebay for the sellers of the batteries and charger...or you may find them cheaper elsewhere.

I received the batteries and charger first. The batteries were not initially charged. I placed them in the charger and 5.5 hours later they were fully charged to 4.20vdc each. They sat for three days and I rechecked the voltage and they were at 4.17. The readings were identical on each battery.

Two days later I received the battery pack holder. I put the batteries in the new holder. Checked the voltage and then inserted the battery pack in the V3i. When I turned it on the battery level indicated 12.39vdc.

I will admit when I first saw the size difference of AA verses Li-ion 3.7vdc I was concerned about them fitting into the detector. No worries...the new setup slides in the detector just like the original battery pack.

The Li-ion battery pack setup weighs 4.7 ounces less than the PowerEx NiMH battery pack.
