From its Tier 1 LFP cells to its generous operating parameters, this battery redefines versatility and durability when it comes to lithium power storage, and boasts comprehensive BMS protections against Over/Under Voltage and Over Current statuses, as well as a thermal management system that affords a generous operating temperature range for all you winter warriors.
The HUSKY 2 comes with state-of-the-art features to enhance the safety and visibility of your power. Not only is it housed in an IP65-rated, vibration-resistant casing, and equipped with an advanced BMS capable of auto-balancing cells and full CANBus & RS485 communication protocols, but it also boasts an automatic self-heating function which supports cold weather charging, ensuring you have reliable power through every season. But that’s not all.
We pair the 12V HUSKY 2 with a state-of-the-art 2000W inverter from AIMS Power. Designed for a diverse range of applications, this pure sine inverter guarantees reliable DC to AC power conversion for your RV, camper van, emergency power supply, backup system, or mobile power setup. Plus, this inverter’s pure sine wave output allows the unit to provide cleaner power, with greater efficiency, to your equipment and appliances than the modified sine alternative. This means less noise coming from your power system, motors that run cooler, and equipment that runs smoother from start to finish, for even the most sensitive of use-cases. With extensive protections and connections, this robust 2kW inverter is an essential component for any battery system or power supply.
Equipped with the 12V HUSKY 2, you’ll be saving space and weight no matter the application, and you can rest easy knowing you’re powered and prepared day in and day out. Shop the all-new 12V HUSKY 2 & HUSKY 2 Kits today.

Product FAQs
BigBattery Frequently Ask Questions
Q1. Can your batteries be used in series?
A1. We no longer offer our batteries for use in series.
Q2. Do your batteries have a thermal management system?
A2. All of our batteries have a thermal management system that is controlled by the BMS (Battery Management System). This Thermal management system will not only prevent the battery from being used if the temperature is too high, but also if the temperature is also too low.
Q3. Can I use my OEM charger?
A3. No. Lead acid battery chargers charge at different currents and voltages than our lithium batteries. Using your OEM charger can damage your battery cells and void your battery’s 10 year warranty. We have several chargers optimized for and calibrated to every battery we sell.
Q4. Why does the voltage drop when unplugging the charger?
A4. The voltage drop that you experienced is called the “bubble voltage” and is perfectly normal for Lithium Batteries. LiFePO4 batteries behave differently than other battery chemistries. The Voltage vs Capacity is not linear. For example, if you have a voltage between (13.3 – 14.6) or (26.6 – 29.2) or (53.6 – 58.4) you will have more than 99% of the capacity. This essentially means that “Bubble Voltage” contains less than 1% of the entire capacity and the drop when a load is placed is instant.
Q5. Can I leave my batteries outside?
A5. No. Our batteries are not marine rated or weather proof, so leaving them out under the sun all day or in the rain can damage the batteries. (This type of damage is not covered under the 10 year warranty.
Q6. How many years will my battery last?
A6. Lithium Iron Phosphate (LifePO4) batteries can be cycled from 3000 to 7000 times. If you cycle the battery daily with an 80% DoD (Depth of Discharge), then you can get even more than 10 years of use from your battery.
Q7. How do I install my battery?
A7. All of our batteries come with free ring terminals that can be used to connect your battery to your inverter, cart, or busbar system. We also sell a parallel busbar that can be used in tandem with the included ring terminals to parallel multiple batteries.
Q8. What is the difference between the 12 A and the Upgraded Charger?
A8.
Upgraded Charger:
- Charging Current: 15A
- Input Voltage: 110V / 220V
- Output Voltage: 58.8v
- Charging Time: 5 h (approx)
- On-Board Charger: Yes
- Protection: IP65
12A Charger:
- Charging Current: 12A
- Input Voltage: 110 / 22V
- Output Voltage: 45V,50.4V,58.8V
- Charging Time: 6.5 h (approx)
- On-Board Charger: No
- Protection: IP50
Q9. Doe Big Battery sell used/surplus batteries?
A9. In the past Big Battery sold refurbished batteries, such as solar batteries made from recertified Nissan Leaf modules. As of the year 2020, all batteries sold are new, never-previously-cycled batteries that come with a complimentary 10 year warranty.
Q10. Do you ship outside of the United States of America?
A10. We only ship within the continental United States. All shipping is done via ground shipping methods. We recommend looking into a freight forwarder to receive shipments outside of the continental United States of America.
