This is a 12V LiFePO4 power and control package built around the BigBattery HUSKY 2 (INV) battery, paired with the Links2 Node 12 RV control module and the Links2 Vision 10 embedded display. It is designed for RVs, boats, and small off-grid homes that need battery storage plus a centralized system for managing lights, tanks, pumps, and other 12V loads from one screen.
Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
Why This Matters
Combining a LiFePO4 battery with a dedicated control module is not the same as adding a battery to an existing DC panel. This package is built to talk to the battery, monitor tank and fuel sensors, and control multiple output channels from a single embedded display. Get the wiring and configuration right the first time, and the system runs the way it was designed. Get it wrong, and you risk BMS lockouts, sensor conflicts, or a control node that never syncs properly with the battery.
Battery Characteristics
The HUSKY 2 (INV) battery uses Tier 1 LiFePO4 (Lithium Iron Phosphate) cells inside an IP65-rated enclosure, with self-heating for cold-weather charging protection and an advanced BMS. This is the "INV" variant, meaning it includes inverter communications for compatible Victron-style setups. Delivered capacity is 5.12kWh per DATA.
Wiring & Configuration Limits
[NEEDS VERIFICATION]: Series/parallel expansion limits for the HUSKY 2 (INV) battery are not stated in the supplied data. Do not assume standard lithium series/parallel ratios apply — confirm with BigBattery before wiring multiple units together.
The Links2 Node 12 control module operates at 9-18V DC and accepts a maximum input current of 80A, with four 30A output channels (two configured as H-Bridge sets) and eight 10A dimmable PWM channels. It is designed for 12V RV/DC systems and is NOT rated for direct connection to 24V or 48V battery banks.
Pro-Installer Tip
Undersized or loose control wiring at the Node 12's override switches and digital inputs is a common source of intermittent sensor readings, not battery failure. Loose input connections cause voltage drops that can mimic a bad tank, fuel, or LPG sensor, leading to false alarms or a control module that appears to "lock out" a function. Torque connections to the terminal spec in the manufacturer manual and verify voltage at each input with a digital multimeter or shunt-based monitor before blaming the sensor or the BMS. On the battery side, treat this as a standard LiFePO4 pack: plan around an 80-100% depth of discharge and avoid running it down further on a routine basis, even though the chemistry tolerates deeper cycling better than lead-acid.
Key Benefits
- LiFePO4 chemistry with Tier 1 cells and an advanced BMS for safer, longer-term energy storage.
- IP65 casing and self-heating for all-weather performance and cold-temperature charging protection.
- Inverter communications (INV variant) for tighter integration with compatible inverter/charger systems.
- Links2 Node 12 centralizes control of lighting, pumps, tanks, and other 12V circuits with 12 override switches and 12 digital input channels.
- Links2 Vision 10 provides a 10.1" 1024x600 display with app control, OTG firmware upgrades, and RS485/RVC connectivity for real-time system monitoring.

Compatibility & Fitment
This package is built for 12V RV, marine, and small off-grid applications. The battery includes inverter communications (INV) intended for use with compatible Victron-style inverter/charger setups. The Links2 Node 12 is designed for 9-18V DC systems only and is NOT compatible with 24V or 48V DC architectures. Standard lead-acid chargers are NOT recommended for the LiFePO4 battery — use a charger and charge profile matched to LiFePO4 chemistry. [NEEDS VERIFICATION]: Specific inverter/charger models certified compatible with the INV communications feature are not listed in the supplied data — confirm compatibility with BigBattery before purchase if you have a specific inverter in mind.
Not included: mounting hardware, DC wiring/cabling, external tank/fuel/LPG sensors, and any inverter or charger not explicitly listed in this package.
