48V LiFePO₄ Battery · Inverter Comms · 12-Year Warranty
5.12kWh of Rugged Battery Storage, Built for the Road and Off the Grid
The HUSKY2 INV is a compact 48V, 5.12kWh LiFePO₄ battery built with closed-loop inverter communication, a vibration-resistant IP65/NEMA 4X enclosure, and integrated self-heating. It’s versatile enough to cover golf carts, RVs, vans, boats, food trucks, commercial vehicles, and off-grid or backup power — with app-based remote monitoring built in.
What Makes This Battery Different
5.12kWh, Tier-1 Cells
Tier-1 LiFePO₄ chemistry with a 7,500W max continuous power rating and 150A peak discharge for 3 seconds.
100A Continuous Discharge
Rated for 100A continuous and 150A peak, with 100A of max charge current for reasonably fast recharge.
IP65 / NEMA 4X, Self-Heating
Dust- and splash-resistant with an internal heater, so cold weather doesn’t stop it from charging.
Vibration-Resistant Build
Built to handle the bumps of vehicle-based use — golf carts, RVs, boats — not just stationary installs.
Closed-Loop Inverter Comms
The “INV” designation means it talks directly to compatible inverters over CANBus/RS485 for coordinated charge and discharge.
HUSKY App Monitoring
Track charge status and battery health in real time from a dedicated iOS or Android app.
Up to 16 Units in Parallel
Scale from one battery up to a much larger bank on the same platform as power needs grow.
Compact, Lightweight Form
A 100 lb, space-conscious footprint built to drop into tight compartments — vehicle, boat, or utility room alike.
One Battery, a Lot of Different Jobs
The HUSKY2 INV isn’t built around one specific use case — it’s a general-purpose 48V lithium battery meant to replace lead-acid or older lithium packs across golf carts, utility carts, UTVs and LSVs, Class A/B/C RVs, camper vans, food trucks, commercial vehicles, and stationary off-grid or backup setups alike. The “INV” in its name refers specifically to its closed-loop inverter communication — it’s built to talk directly to a compatible inverter over CANBus or RS485, rather than just supplying raw DC power.
That communication is currently confirmed with the EG4 6000XP, EG4 12000XP, and Victron MultiPlus-II 3000/5000 inverters. Day to day, the HUSKY app gives a real-time look at charge level and battery health from a phone, independent of whatever monitoring ecosystem the paired inverter uses. Up to 16 units can run in parallel for larger banks, and the vibration-resistant, IP65/NEMA 4X-rated enclosure with built-in self-heating means it’s equally at home bolted into a moving vehicle or sitting in a garage.

Common Questions
What does the “INV” in the name mean?
It indicates this version includes closed-loop inverter communication over CANBus/RS485, letting it coordinate directly with a compatible inverter rather than just supplying raw DC power.
What inverters does it actually work with?
Closed-loop communication is confirmed with the EG4 6000XP, EG4 12000XP, and Victron MultiPlus-II 3000 and 5000. It can supply power to other 48V inverters too, just without that same live communication link.
Is this only for RVs and vans?
No — it’s built as a general-purpose 48V battery. BigBattery lists it for golf carts, utility carts, UTVs and LSVs, Class A/B/C RVs, camper vans, food trucks, commercial vehicles, and stationary off-grid or backup power alike.
Can it be installed outdoors?
It’s IP65/NEMA 4X-rated with self-heating, which covers dust and splash resistance and cold-weather charging. For fully exposed, permanent outdoor installation, confirm the specific conditions against the spec sheet.
How do I monitor it?
Through the dedicated HUSKY app, available for iOS and Android, which shows charge level and battery health in real time — independent of whatever monitoring system the paired inverter uses.
What’s the warranty?
12 years, covering defects in materials and workmanship.
Do I need a licensed electrician to install it?
Given the voltages and currents involved, installation should be handled by a qualified, licensed electrician or installer familiar with your local code requirements — including vehicle- or marine-specific code where applicable.
