The HUSKY 2 comes with state-of-the-art features to enhance the safety and visibility of your power. Not only is it housed in an IP65-rated, vibration-resistant casing, and equipped with an advanced BMS capable of auto-balancing cells and full CANBus & RS485 communication protocols, but it also boasts an automatic self-heating function which supports cold weather charging, ensuring you have reliable power through every season. But that’s not all!
We pair the 12V HUSKY 2 with a cutting-edge 2000W inverter and charger from AIMS Power. This dual inverter-charger boasts a 300% surge capability, automatic frequency detection, power factor correction, adjustable multi-stage charging, and a built-in AC transfer switch, guaranteeing incredibly low transfer times. When paired with a lithium battery bank, this automatic transfer switch creates seamless transitions between grid, solar, and battery input priorities and serves as an essential component for any mobile or backup power system. This inverter also comes equipped with an integrated low-frequency transformer. This heavy-duty transformer greatly reduces the levels of harmonic distortion during the conversion process, resulting in a cleaner, more efficient delivery of power to the rest of your system, increasing overall system reliability and efficiency, and creating a significantly quieter operating experience. With robust features, setting selectability, and extensive protections, this AIMS inverter is one of the safest, most reliable, most versatile, and most essential inclusions for any energy enthusiast looking to set up or upgrade their power system.
Equipped with the 12V HUSKY 2, you’ll be saving space and weight no matter the application, and you can rest easy knowing you’re powered and prepared day in and day out. Shop the all-new 12V HUSKY 2 & HUSKY 2 Kits today!
