Automatic Dual Battery Charger, 90A
A secondary battery on board requires a dedicated charging solution. The Charge Mate Pro makes it possible to distribute the charger or alternator current effectively between two battery banks such as a starter and a service battery. The Charge Mate Pro connects both batteries during charging and keeps them isolated when discharging. This significantly reduces the risk of a flat starter battery for example.
The Charge Mate Pro offers an additional advantage over mechanical charge relays, by limiting the charge current to the second battery. The primary battery, like a starter battery, is therefore charged with priority. The return current is automatically blocked even when the secondary battery has a higher voltage. An emergency start function is possible by connecting an optional bypass switch to the Charge Master Pro.

Switch, 200A, 12V, Quad Lug
InPower's ABS3 Series of Auxiliary Battery Switches are the ideal solution for charging and isolating an auxiliary battery from a vehicle's chassis battery and alternator. The auxiliary battery is charged from the chassis battery and alternator while the chassis battery is protected from auxiliary battery load discharge. Since the ABS3 is bidirectional, a charging device (such as a battery charger or genset) that is connected to the auxiliary battery will also supply charging current to the chassis battery.

  • InPower ABS3-200B Auxiliary Battery Switch
  • Category: Battery Separators
  • Manufacturer: Inpower
  • Switch Type: Solid State
  • Current Rating: 200A
  • Operating Voltage Range: 7-18VDC
  • Terminals: 3/8-16 Brass Bolts with Copper Washers 
  • Ingress Protection: IP67
  • LED Indicator for visual switch status 
  • Electronic, solid state design means no moving parts that will wear-out
  • Ideal for charging auxiliary battery and isolating it from vehicle chassis battery and alternator
  • Prevents over-current, over-temperature and under voltage
  • Quad lug model allows the ABS3 to serve as a high current junction block 
  • Allows parallel power cabling between the auxiliary and chassis batteries
