Got this from a E-bay Seller from Ukraine. Already put in my new NCR Panasonic 18650B Batteries. The starting VOltage is 12.43V (based on my multimeter which is a little low on readings). The Etrac came on with full bars. Will be running down the batteries to see how long they will last before they go flat. The 18650b Batteries are 3400mah. Should last a long time. Will base my voltage readings on my multimeter to keep it ending at the same start and end voltage. Actual start voltage is closer to 12.54.
First 17 hours of testing Voltage only dropped from 12.43 to 10.83V (3.61V per Cell) Lots of juice left to go. The Minelab 1600 starts at 11.40v 1and drops fast to around 10.50 first hour.
