VOLTAGE ** CC = Constant Current | CV = Constant Voltage **Return to Bulk Voltage - The KickAss DCDC charger range implements an intelligent voltage monitoring system to determine the point at which the charger transitions from Float back to bulk. This ensures the battery SOC is always maintained in an optimal state, regardless of whether the battery is being actively discharged or in a standby / low discharge state.
PRODUCT FEATURES 25 / 40A Charger Output The 25A and 40A models deliver a true continuous output of 25A and 40A respectively, ensuring consistent and reliable battery charging. Bluetooth Monitoring and Control All models support connection to a mobile Bluetooth app, available on the App Store and Google Play.

Hybrid Compatible The maximum input current can be configured via the mobile Bluetooth app, allowing the charger to limit alternator draw. This feature is useful for vehicles with low-power alternators or hybrid systems with limited output capacity. Note: Always verify the alternator/generator’s output voltage and current ratings in hybrid vehicles.

Starter Battery Isolation If the alternator’s voltage drops below the charger’s input cut-out threshold, the charger will enter isolation mode to prevent draining the vehicle’s starter battery. Support for Multiple Battery Chemistries Includes selectable charging profiles for LiFePO4, AGM, WET, CAL, and GEL battery types.
