BigBattery Introduces Budget Friendly HUSKY 2e Lithium Battery

BigBattery has announced a new entry point into its lithium battery lineup with the upcoming 12V HUSKY 2e, a streamlined and more affordable version of its premium HUSKY 2 INV deep cycle battery. The HUSKY 2e stores 314Ah and delivers 4kWh of capacity, positioning itself as an accessible option for RV owners, boat enthusiasts and off grid solar system users who want quality lithium power without the premium price tag.

The new model joins an existing family that includes 12V, 24V and 48V LiFePO4 configurations. This expansion signals a shift in the lithium battery market, where previously high cost barriers are beginning to lower for everyday vehicle and adventure lifestyle consumers.

The original 12V HUSKY 2 INV remains BigBattery’s flagship offering, storing a full 5.12kWh with 400Ah capacity. The new HUSKY 2e trims that slightly to 4kWh while maintaining the same core engineering philosophy. Both models feature Tier 1 LiFePO4 cells, smart battery management systems with automatic cell balancing, and protection against overcharge, overdischarge, short circuits and temperature extremes.

The key difference lies in price and capacity. BigBattery’s CEO Eric Lundgren explained the strategy: “HUSKY 2e will soon give more RV, boat and solar system owners a lower cost entry into the 12V HUSKY 2 platform with the same advanced engineering expected from our products.” This approach acknowledges that while premium models serve serious power users, many recreational RV owners seek reliable lithium technology at more moderate investment levels.

Both models include built in self heating that activates before charging, allowing operation in temperatures as low as negative 4 degrees Fahrenheit. This cold weather capability matters for RV owners who travel or store their vehicles during winter months. The IP65 rated, vibration resistant enclosure handles road vibrations, water exposure and outdoor conditions, backed by a 12 year U.S. based warranty.

Key Features That Matter for RV Owners

Both the HUSKY 2e and HUSKY 2 INV offer closed loop communication with supported inverters through CANBus and RS485 protocols. This means your inverter receives real time state of charge information from the battery management system rather than estimating it from voltage alone, improving reliability and system performance.

App based monitoring through the HUSKY smartphone application for iOS and Android lets you track battery status remotely. An LED indicator on the battery itself displays state of charge visually. With LiFePO4 chemistry rated for 4,000 to 6,000 plus cycles at 80 percent depth of discharge, these batteries should provide 10 to 15 years of reliable service for typical RV users.

The batteries require no electrolyte watering or equalization maintenance like traditional flooded lead acid batteries. Standard M8 terminals enable straightforward integration into properly specified electrical systems. One 12V HUSKY battery matches the capacity of four 12V 100Ah lead acid batteries wired in parallel, yet occupies a single compact case measuring 12.6 by 18.1 by 9.8 inches.

What RV Buyers Should Expect

For a typical 200 watt continuous RV load, BigBattery estimates a single 12V 400Ah battery runs appliances for roughly 24 hours. Actual runtime depends heavily on your specific appliances, inverter efficiency, temperature and other simultaneous loads. RV owners should calculate their daily energy consumption before purchasing and size their battery bank accordingly.

Installation requires checking existing wiring, fuses, converters, chargers and alternator charging systems before setup. Charging equipment must be configured to LiFePO4 parameters specific to lithium chemistry. RV warranty considerations have become increasingly important as owners invest in premium power systems, and BigBattery’s 12 year warranty plus lifetime U.S. based technical support and free end of life recycling add significant value.

The HUSKY 2 INV lineup also supports expansion: owners can wire up to 16 matching batteries in parallel to reach 81.92kWh in a single lithium bank for larger systems. At 24V and 48V configurations, higher voltage systems reduce current draw for the same power output, minimizing voltage drop and heat loss in longer cable runs typical of larger RVs and marine installations.

Camper van and travel trailer builders increasingly specify lithium batteries as standard equipment, reflecting industry wide recognition that lithium offers superior performance and longevity compared to lead acid alternatives. The introduction of a lower cost HUSKY 2e model suggests this transition will accelerate as more consumers find lithium within reach.

Cost pressures in the RV market make timing crucial for budget conscious buyers considering upgrades. BigBattery HUSKY products are available now through bigbattery.com with shipping from Texas.
