The CBA amplifier requires an AIU or CBA to work. If you do not own an AIU or CBA, you can purchase a 500 Watt System, 1000 Watt System or 2000 Watt System that includes the AIU.

If you own an AIU, then you can add up to four CBA amplifiers.

If you own a CBA and a CBA amplifier and want to add this to create a 1000 Watt or 2000 Watt system, then you will need to fill out an RMA request and send in your CBA and CBA amplifier(s) to have them recalibrated for a 1000 Watt or 2000 Watt system. It also needs to be added to the comments section of your order that this CBA amplifier will be used in a 1000 Watt or 2000 Watt system.

Capabilities

Perform Fast, High Power Testing

Test at 5 times the power with a CBA amplifier in between an AIU or CBA and your battery
500 watt discharge with a single amp and an AIU or CBA
1000 watt discharge with two amplifiers, a harness and an AIU or CBA
2000 watt discharge with four 20X* amplifiers, a harness and an AIU or CBA
Designed for commercial or industrial use
Test a Lithium cell at up to 120 amps / 500 watts with a single amplifier
Test a Nickel cell at 160 amps regulated down to .9 volts with a single amplifier
Test batteries at or near their current and temperature limits
Support for operation with one or more CBA 500 watt amplifiers and an AIU or CBA V or CBA IV (CBA III units require Extended license)

* 20X amplifiers are a special order item.

Test at Real World Load Conditions

Increases 100 watt continuous capability of CBA to 500 watts
Discharge rates at up to 500 watts or 160 amps maximum, whichever is higher
High voltage testing at up to 55 volts; the equivalent of 1 to 38 NiCad or NiMh cells

Extended Software License Unlocks Features for Serious Battery Testing

Programmable automatic duty cycle test with up to 999 second on/off cycle periods
Regulated constant power discharge (current goes up as battery voltage drops)
