How long will a 400Ah lithium battery last?

The runtime of our 12V 400Ah battery depends entirely on the power draw (watts) of the appliances you connect. With a massive 5120Wh of usable energy, it can power your essential devices for hours or even days.

Here are some real-world examples based on continuous use:

Air Conditioner (1100W): up to 4.6 hours
Microwave (1000W): up to 5.1 hours
Washing Machine (500W): up to 10.2 hours
TV (100W): up to 51 hours
Fridge (50W): up to 102 hours
Fan (40W): up to 128 hours

Quick Tip: To estimate the runtime for your own devices, use this simple formula:
Runtime (in hours) = 5120 / (Wattage of your device)

Can I use LiTime LiFePO4 Lithium batteries as starting batteries?

No, LiTime 400Ah lithium batteries are designed for energy storage, not as starting batteries. Please avoid using them to start any devices.

To learn more about the differences between these two battery types, check out our blog on Deep Cycle vs. Starting Batteries.

For marine starting applications, visit our LiTime Marine Cranking Batteries for suitable options.

How do I charge the 12V 400Ah LiFePO4 battery?

Our 12V 400Ah battery is designed for flexible charging. There are three primary ways to charge it, all of which require a charger compatible with LiFePO4 chemistry.

1. Solar Panels
Yes, you can charge your battery using the sun. A quality MPPT solar charge controller is required to manage the power safely and efficiently.

With 1200W of solar panels, you can fully charge the battery in a single day, assuming approximately 4.5 hours of peak sunlight.

2. Vehicle Alternator or Generator
You can charge on the go or with backup power.

From your vehicle's alternator: A DC-to-DC charger is the recommended tool for a safe and effective charge while driving.
From a generator: Use a compatible LiFePO4 smart charger that converts the generator's AC output to the correct DC power for the battery.

3. LiFePO4 Smart Charger (Standard AC Outlet)
This is the most direct method. Simply connect a dedicated LiFePO4 smart charger to the battery and plug it into a standard wall outlet.

Recommended Charge Settings

For methods 2 and 3, use a charger with the following settings for optimal performance and speed:

Charge Voltage: 14.2V to 14.6V
Charge Current:Standard (80A / 0.2C): Reaches 100% full charge in about 5 hours.Fast (200A / 0.5C): Reaches ~97% charge in about 2 hours.

Learn more about: Can I Charge LiFePO4 Batteries With a Normal Charger?

Can I charge LiTime LiFePO4 lithium batteries in cold weather (under freezing temperatures)?

Please be aware that this 400Ah model does not featured low-temp protection and should only be charged when the battery's temperature is above 32°F (0°C). Charging in freezing temperatures will damage the cells. On cold days, the best practice is to bring the battery indoors to charge.

For a detailed explanation, please read our complete Guide to LiFePO4 Battery Temperature Ranges.

For Charging in Freezing Temperatures: If your application requires charging in sub-zero weather (e.g., winter RVing, off-grid cabins), consider our LiTime Cold Weather Batteries. These advanced batteries include a built-in system (low-temperature charging off protection) that automatically manages charging in the cold, protecting your investment.

How do I store LiTime LiFePO4 lithium batteries?

For optimal longevity, store your LiTime LiFePO4 batteries under the following conditions:

Storage Recommendations

State of Charge (SOC): Store batteries at a 50% state of charge. Avoid storing them fully charged or completely discharged.
Regular Recharging: If storing for an extended period, recharge the batteries to 50% at least every three months to prevent deep discharge and maintain cell balance.
Temperature: The ideal storage temperature is between -10℃ to 50℃ / 14℉ to 122℉.
Humidity: Maintain a relative humidity of 45% to 75%.
Protective Casing: It is highly recommended to store the batteries in a dedicated battery box to protect them from physical damage, dust, and moisture.

Best Practices for Long-Term Storage

For storage exceeding three months, adhering to these guidelines will significantly preserve your battery's health and performance:

Disconnect Completely: Ensure the batteries are disconnected from all loads and charging sources. This prevents slow parasitic drains that can lead to over-discharge.
Avoid Extreme Temperatures: Storing batteries outside the recommended temperature range can accelerate degradation. In particular, high heat can permanently damage the battery's capacity.
Cycle Before Use: After a long storage period, it's good practice to cycle the battery (one full charge and discharge) before putting it back into regular service.

Can I connect the 400Ah lithium batteries in series or parallel?

Yes. LiTime 12V deep cycle lithium batteries can be connected in both sereis and parallel to create a bigger battery system.

Series: Connect up to four batteries in series to create a higher voltage system (e.g., 24V, 36V, or 48V).
Parallel: Connect up to four batteries in parallel to increase the total capacity (Ah) to 1600Ah.
Series-Parallel: Build a larger bank of up to 16 batteries in a 4S4P configuration (4 in series and 4 in parallel) for maximum power and capacity.

⚠️ Critical Connection Requirements

To ensure safety, performance, and longevity, all batteries in a connected bank must meet these conditions:

Identical Model: Use the exact same battery model (e.g., LiTime 12V 400Ah) with the same capacity (Ah) and BMS rating (A).
Same Brand: Never mix batteries from different brands. Each brand uses a unique Battery Management System (BMS) that is not compatible with others.
Recent Purchase: The batteries should be purchased close together, ideally within one month, to ensure they are from the same manufacturing batch for balanced performance.
Voltage Matched: Before connecting, ensure all batteries are fully charged and their voltages are balanced to within 0.1V of each other. This prevents large inrush currents that can damage the batteries.

Bigger battery bank

I was looking for more power for my house side of my bus. I had 4 L16 amg batteries. They just didn’t do it. So I started my search for “More Power” I looked at all 12v 400amp hour batteries made !!! Yes made ! Why did I go with LiTime batteries. Well the first point was cost I purchased them from their site litime.com they were running a sale I paid $912 per/battery if you bought 4. Yes that’s 1600amp/hours. With my specific set up it has two magnum 3012H inverters so I spilt the inverters so each had there own battery bank . Now to be fair li time was not my first pick like I said I looked at every 400amp/hr battery out there. There are ones with Bluetooth , and heaters to charge below 32*. Well my set up is kinda special ( 2020 Entegra Anthem) it has a special built in battery box that receives heat from my main living area . So heat was not needed. Second by making two battery banks I used two VictronConnect ip65 500v shunts to monitor the SOC. As you can see I didn’t need any of them fancy features I just needed power. I will be doing a in depth video for LiTime to be used on their web site. No I was not paid nor did I receive any compensation for this review . Take a look at Li Time batteries. If you just need power at a good price and the fancy features aren’t needed then theses are great batteries. I will be doing a one year review on their site ( if they ask me )

A real beast of a battery

Maybe it's a little big. Maybe two 200amps would be better. I can't pick it up without help. Tested with inverter and it didn't blink!

So far so good

so far the batteries I ordered I’ve worked exactly like they were advertised. I love the weight. I saved almost 1000 pounds can’t wait to try them for longer. We have an amount of 75 foot House Boat. So far a great product.

Nice battery

Shipped on time and received a couple days early
I had a couple tech questions and they were promptly answered

12 hours of AC

These are a game changer for our boat. AC overnight without the generator..

Fantastic easy to charge and hook up!

We received the battery with no issues, right on time. We charged it up over night and hooked it into our invertor the next day. Everything went smoothly and we are very pleased with the power accessible.now even with the rainy days. Yay!!

I received the battery in 4 days

I haven't had the chance to use the battery yet but the quality of the case and the weight was much less than the old 6 volt batteries plus the energy storage should be hugely beneficial.
