Powermaster 16 Volt IntelliCharger:

This ''smart charger'' features a custom circuit board inside with a microprocessor that controls the constant current/constant voltage features. The microprocessor analyzes the battery when connected, and if voltage is below 4V or does not charge to the correct voltage in a ten-hour period the charger will shut off.

Voltage Reducer:

Powermaster's 16 Volt Step-Down module features a heavy duty aluminum heat sink, diodes, and the highest quality 8 AWG stranded wire. A fuse holder is included, that is under-hood safe, and the unit can be mounted in any location. Perfect for voltage sensitive electronics, our Step-Down has dual outputs, 2.4V and 3.6V for running with or without an alternator.
