The West Mountain Radio CBA Charger can be used with a West Mountain Radio CBA IV and a user provided battery charger to automate life cycle tests, automatically alternating between periods of charging the battery and discharging the battery. By automatically switching between charge and discharge cycles of the battery, a hands-free lifetime test of the battery can be performed.

When the unit is idle, the two pairs of Powerpoles® are open. When the unit is in a charging state, the two Powerpoles® are connected together, connecting the user provided battery charger to the battery.
CBA Charger interface requires a user provided battery charger compatible with your battery. CBA Charger interfaces to this external charger.
Can measure the current going from the charger into the battery, and this current is logged by the software.
Two general-purpose inputs are available that can be used by the CBA Charger and software to determine when a charge cycle is complete. These inputs could be connected to a charge complete LED on the user provided battery charger.
Two general-purpose outputs are available that can be used to send start charging or stop charging messages to the user provided battery charger. These outputs could be connected to a push-button on the user provided battery charger.
