BigBattery 12V 3X HUSKY 2 Inverter Kit + AIMS Inverter Charger

Take your power system to the next level with the 12V 3X HUSKY 2 Lithium Battery Kit – AIMS Edition, delivering an impressive 15.36kWh of ultra-reliable, high-capacity LiFePO₄ energy. Whether you're powering an RV, trailer, boat, mobile business, or off-grid home, this triple-battery system is designed to meet the most demanding energy needs with superior performance and all-season readiness.

At the heart of this kit are three 12V HUSKY 2 batteries, BigBattery’s most energy-dense 12V solution to date. Built using Tier 1 LFP cells, each battery is encased in an IP65-rated, vibration-resistant housing and equipped with an advanced BMS for auto-balancing, CANBus & RS485 communications, and full protections against over/under voltage, overcurrent, and temperature extremes. The integrated self-heating function ensures optimal performance even in frigid conditions.

The HUSKY 2s are paired with a rugged and intelligent 2000W AIMS Power Pure Sine Inverter-Charger. Featuring 300% surge capacity, power factor correction, a low-frequency transformer, and a built-in AC transfer switch, the AIMS inverter enables seamless transitions between grid, battery, and solar input. It supports multi-stage charging, automatic frequency detection, and provides cleaner power output with lower distortion—ideal for sensitive electronics and high-demand loads.

With this comprehensive setup, you’ll enjoy efficient, low-maintenance, plug-and-play power that’s engineered for both reliability and flexibility. Whether on the road, on the water, or off the grid, you’ll be ready for anything.

Understanding Your Power Needs

Power Calculation Guide

Sizing Metric Formula & Example
Energy Consumption (Wh) Formula: Watts × Hours
Example: 60W × 4 hrs = 240 Wh
Battery Capacity (Ah) Formula: Watt-hours ÷ System Voltage (V)
Example: 240 Wh ÷ 12V = 20 Ah
Inverter Size (W) Formula: Total Watts × 1.25 (safety margin)
Example: 300W × 1.25 = 375W → Use 400W inverter
Total Load Power (W) Formula: Sum of all appliance watts used simultaneously
Example: Light (10W) + Fan (75W) = 85W
Runtime (hrs) of Battery Formula: (Battery Ah × Voltage) ÷ Total Load (W)
Example: (100Ah × 12V) ÷ 240W = 5 hrs
