Field Guardian Commander (FGB200) Low Impedance Electric Fence Charger, UL Listed, Rated at 2 Joules (Actual 1.1-1.6)
The FGB200 (a match for the Power Wizard 2000B) is the strongest battery-powered charger that we offer. It is good for containing horses in medium to large pastures. Regarding batteries, with the charger operating at full power a 60 amp-hour battery will last two weeks and a 110-amp-hour battery last 4 weeks. We do not offer large “deep cycle” batteries (the kind needed) on this website, but they can be obtained at www.ebatteriestogo.com or at almost any local store that sells boat or golf cart batteries. Operating this charger in half-power mode will lengthen the battery discharge time it by at least 40 per cent. Voltage data: This electric fence charger will keep 4,800 volts on the line (in full-power mode) when the weed burden is minor (providing no more than a 500-ohm path to the ground), and it will keep about 2,600 volts on the line (more than enough to reliably shock horses) when confronting a large 100-ohm weed burden. In half-power mode it can still shock horses, but the voltage falls to about 2,400 volts with a 200-ohm weed burden and to 1,800 volts or so (below the 2,000 desired to reliably shock horses) with a 100-ohm weed burden. Joule range: At full power the FGB200 puts out 1.1 joules on a 500-ohm circuit and 1.6 joules on a 200-ohm circuit. At half power it puts out 0.6 joules (while maintaining 3,000 volts) on a 500-ohm circuit and 0.7 joules (while maintaining 2,400 volts) on a 200-ohm circuit. (For more about joules see Charger Safety, Horse Fences, and Joules). Other animals: The FGB200 is our best battery-powered charger for containing livestock (including cattle, pigs, sheep, goats, and exotics), for excluding deer, and for keeping out predators (including foxes, coyotes, wolves, javelinas, feral pigs, bears, and bison). General data: The FGB200 can operate in either half-power or full-power mode. (Both modes require a fairly substantial battery, on the order of 60 amp hours, in order to avoid frequent recharging.) The charger comes with an all-weather case, built-in lightning protection, installation instructions, a 3-year warranty against manufacturing defects and lightning damage, and a flashing light that shows when the unit and its immediate fence connections are working properly. Battery not included.
