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 state-of-the-art 2000W inverter from AIMS Power. Designed for a diverse range of applications, this pure sine inverter guarantees reliable DC to AC power conversion for your RV, camper van, emergency power supply, backup system, or mobile power setup. Plus, this inverter’s pure sine wave output allows the unit to provide cleaner power, with greater efficiency, to your equipment and appliances than the modified sine alternative. This means less noise coming from your power system, motors that run cooler, and equipment that runs smoother from start to finish, for even the most sensitive of use-cases. With extensive protections and connections, this robust 2kW inverter is an essential component for any battery system or power supply.
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!

A: More reliable power delivery through stable voltage under load, quicker recharge cycles, longer lifespan, reduced downtime or maintenance, and greater overall energy efficiency.
Maintenance Tip
-
Install the HUSKY 2 Kit with AIMS charger in a cool, dry, and well-ventilated area to maintain stable 12V performance and prolong battery life.
-
Regularly inspect terminals, connectors, and wiring for corrosion, looseness, or damage to ensure safe and reliable operation.
-
Clean battery and charger surfaces with a soft, dry cloth to remove dust and prevent heat buildup.
-
Protect the kit from direct sunlight, moisture, and extreme temperatures to preserve cell health and charger efficiency.
-
Avoid deep discharges; monitor state of charge to maintain long-term capacity and performance.
-
For long-term storage, maintain the battery at 50–60% charge and disconnect from all loads and the charger.
