MISC - FS: MFJ 4416B Super Battery Boosters Nice workng battery booster. $160 shipped. Zelle, MO, or check. MFJ 4416B Super Battery Boosters keep your transceiver operating at full efficiency and performance by eliminating low or marginal voltages in the mobile environment. They accomplish this by boosting input voltages as low as 9 V up to the desired 13.8 V at 25 amps peak with a typical efficiency of close to 90 percent. Even at their compact, lightweight 1.3 lbs., they are designed to be rugged, reliable, and easy to use. The MFJ 4416B super battery boosters include Anderson PowerPole connectors and high-current, 5-way binding posts for both the DC input and regulated output. An internal 30 amp input fuse protects them from excess output current demands. There are also selectable limits on the minimum voltage that can be accepted, protecting you from over-discharging a battery and possibly damaging it. Should regulation be lost, they also include output over-voltage crowbar protection.
