The BigBattery 48V HUSKY 2 INV Brings 5.12kWh of Self-Heating LiFePO4 Storage With Inverter Communication to RVs, Vans and Off-Grid Systems
The BigBattery 48V HUSKY 2 is a 51.2V, 100Ah lithium iron phosphate battery that stores 5.12kWh in one rugged, IP65-rated case. It is built for RV, van, off-grid and backup power systems, and this INV version communicates with EG4 6000XP and 12000XP and Victron MultiPlus-II 3000 and 5000 inverters.
Tier 1 LiFePO4 cells, an advanced battery management system and built-in self-heating keep it safe and working in cold weather, and it needs no watering or routine maintenance. BigBattery backs the HUSKY 2 with a 12-year warranty and lifetime USA-based technical support, and it ships from Texas.
BigBattery 48V HUSKY 2 INV Lithium Battery Features
100Ah, 5.12kWh in One Case
One HUSKY 2 stores 5.12kWh at 51.2V nominal. That is the same energy as several lead-acid batteries in a single IP65 case, at about 100 lbs.
Strong Output
It delivers 100A continuously with a peak of 150A for 3 seconds, and accepts up to 100A of charge current for fast recharging from a charger, inverter-charger or solar.
Inverter Communication (INV Version)
Closed-loop CANBus and RS485 communication with the EG4 6000XP and 12000XP and the Victron MultiPlus-II 3000 and 5000, so the inverter reads true state of charge and adjusts charging for the battery.
Self-Heating for Cold Weather
Built-in self-heating lets the battery charge down to -4°F, which suits RVs, boats and cabins used in winter.
IP65 and Vibration-Resistant
The IP65 / NEMA 4X enclosure resists dust and water, and the vibration-resistant construction is built for road and marine use.
Advanced BMS and App Monitoring
The battery management system protects against overcharge, over-discharge, short circuit and temperature extremes. The HUSKY app lets you monitor battery status remotely.
Expand Up to 16 in Parallel
Connect up to 16 HUSKY 2 batteries of the same model in parallel to build a larger bank.
Real-World Applications
48V RV and van builds. Run a 48V inverter and high-power appliances efficiently with lower current.
Off-grid cabins. Store solar for a 48V off-grid system and add batteries as you grow.
Home backup. Pair with an EG4 or Victron inverter for essential circuit backup.
Mobile power. Power job sites and mobile businesses from a sealed, vibration-resistant battery.
How It Compares to Common Alternatives
Versus lead-acid batteries. A lead-acid bank with the same usable energy would weigh several times as much and need regular maintenance. HUSKY 2 can be discharged much deeper and lasts thousands of cycles.
Versus smaller 100Ah lithium batteries. Wiring several small batteries together adds cables, bus bars and connection points. One HUSKY 2 replaces several of them with a single case and a single BMS.
Is This HUSKY 2 Battery the Right Fit
System voltage. 48V systems.
Inverter. BigBattery lists off-grid closed-loop communication with the EG4 6000XP and 12000XP and the Victron MultiPlus-II 3000 and 5000.
Space. 12.6 x 18.1 x 9.8 in (D x W x H).
Charging. A charger or inverter-charger set to the charge voltages in the specification table, up to 100A.
This may be a good fit if
You want a large, single-case lithium battery
You use your system in cold weather
You need a sealed, vibration-resistant battery for a vehicle or boat
You want closed-loop communication with your inverter

Installed this on a portable system for roll around convenience.
It was easy to install and wire up and powered right up with no issues.
Hi Randall, thank you for sharing your experience! We're glad to hear the inverter worked well for your system. If you need any more assistance, feel free to reach out. Enjoy your power setup!
Thank you for the 5-star review! We’re glad you’re enjoying your Jackery setup, and we really appreciate you sharing the photo. It looks like a great setup!
Jackery performed well, durable, easy to use, recommend
The Jackery was my first power station. I had a lot to learn and much research to do. Outbound Power was easy to work with, they answered the phone and helped with the delivery. We used it constantly on our first camping trip with it, powering our 12v cooler, charging phones and LED lights. No issues at all. Product is well built, durable and easy to understand. Might even get the solar panels later this year. I'd recommend.
Hi Gordon, thank you for sharing your experience! We're thrilled to hear the Jackery served you well on your camping trip. Enjoy exploring with your power station, and we'd be happy to help with the solar panels when you're ready. Safe travels!
This is the first power station I have owned. I chose the Anker Solix c1000 gen 2 because it had great reviews and was the size I wanted. I live in central California and fortunately we do not have a lot of power outages. With winter coming, I decided to prepare just in case. Ordering the product was easy and Outbound Power had the best price.
The only issue I had was registering the product. Anker provided a QR code which is pretty standard. However, I had to call Outbound Power to get a working link. The gal I spoke to at Outbound seemed surprised I had to call.
Hi Dallas, thank you for sharing your experience! We're glad you chose the SOLIX C1000 and that you found ordering easy. We appreciate your feedback about the registration process and will work to improve it. Stay safe and enjoy your power station!
Outbound Power makes the buying experience so easy
