48V LiFePO₄ Battery · Inverter Comms · 12-Year Warranty
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.
Tier-1 LiFePO₄ chemistry with a 7,500W max continuous power rating and 150A peak discharge for 3 seconds.
Rated for 100A continuous and 150A peak, with 100A of max charge current for reasonably fast recharge.
Dust- and splash-resistant with an internal heater, so cold weather doesn't stop it from charging.
Built to handle the bumps of vehicle-based use — golf carts, RVs, boats — not just stationary installs.
The "INV" designation means it talks directly to compatible inverters over CANBus/RS485 for coordinated charge and discharge.
Track charge status and battery health in real time from a dedicated iOS or Android app.
Scale from one battery up to a much larger bank on the same platform as power needs grow.
A 100 lb, space-conscious footprint built to drop into tight compartments — vehicle, boat, or utility room alike.
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.

GTIN: 850061252296. Warranty: 12 years.
Closed-loop communication is confirmed with these off-grid inverters. Other 48V inverters may work for basic power, but won't have the same live communication link.
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.
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.
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.
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.
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.
12 years, covering defects in materials and workmanship.
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.
