BigBattery 12V OWL MAX 2 - LiFePO4 - 228Ah - 3.018kWh
TAKING IT TO THE MAX, AGAIN! BigBattery’s 12V 3 kWh LiFePO4 OWL Max 2 battery takes all the incredible features you loved from our flagship OWL and OWL Max and adds even more capacity.
On top of brand new LFP cells, our advanced BMS, and 300A Fuse, the OWL Max 2 comes with an additional 418 Wh and 26 Ah of capacity, a sleek stainless steel casing, and an internal fire extinguisher. When you upgrade your RV’s power system with the OWL Max 2, you can cut the weight and space used by your battery bank in half. You’ll be able to provide more than twice the power in the same amount of space while lasting 4 times longer than the lead acid equivalent, all with ZERO maintenance!
With a compact, portable design and the ability to connect several units in parallel for a huge power system, this truly is one of our most versatile solutions. So if you’re looking for a battery that can not only bring you the power you’re looking for, but look good doing it, the 12V OWL Max 2 is the battery for you.

FREQUENTLY ASKED QUESTIONS
Can your batteries be used in series?
We no longer offer our batteries for use in series.
Do your batteries have a thermal management system?
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.
Can I use my OEM charger?
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.
Why does the voltage drop when unplugging the charger?
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.
Can I leave my batteries outside?
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.
How many years will my battery last?
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.
Is BigBattery compatible with all Inverters and Charger Controllers?
Our batteries work great with almost all inverter/charger controller brands. The only brand we are not compatible with is RENOGY. Please confirm that your inverter can be set to the operating parameters of the battery you’re interested in before purchasing. Parameters can be found as a downloadable PDF spec sheet on every battery product page.
How do I install my battery?
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.
What is the difference between the 12 A and the Upgraded Charger?
- Charging Current: 15A
- Input Voltage: 110V / 220V
- Output Voltage: 58.8v
- Charging Time: 5 h (approx)
- On-Board Charger: Yes
- Protection: IP65
Does Big Battery sell used/surplus batteries?
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.
How long before my order ships?
It can take anywhere from a week to no more than two weeks for shipment. This time allows us to assemble, test, and inspect each battery prior to shipping.
Why does shipment take so long?
We build every battery upon order, so shipment may take anywhere from a week to no more than two weeks.This is to allow us to assemble, test, and inspect every unit prior to shipment.
