The LVD is a Low Voltage Disconnect and it serves as several functions. It aids in the charge and discharge monitoring of the battery to do it most efficient and it also cuts out the battery when it see’s a .9 volt left in each cell, NiMH batteries do not like to be completely drained so the LVD helps maintain the health and life of the battery pack.

How fast does it go?

It can move a 170 pound man in full gear approx 165 feet per minute, that equates to almost 2 knots. Every diver is different, We have had divers moving up to 175 feet per minute and some who go about 150 feet per minute.

How long does the battery last?

If you held the switch down the whole time, it will run the battery out in about 35 to 45 minutes. Many variables between divers carry different results. On most of the Divers who helped us complete about 250 endurance dives we were able to run the battery out on a two tank dive. The battery ended up running out on the second dive about 40 percent of the time.
