【Lithium Battery with Grade A Cells】 LiTime 12V 400Ah Lithium Iron Phosphate (LiFePO4) batteries have exceptional quality since they are assembled by Automotive Grade LiFePO4 Cells with UL Testing Certificated, which makes them higher energy density (37.12 Wh/lb), more stable performance, greater power, and excellent 3% self-discharge rate.

【1/3 Lightweight & 10-year Lifetime】 LiTime LiFePO4 battery can run 4000-15000 cycles (10-year lifetime), which is quite superior to lead acid batteries with 200~500 cycles (3-year lifetime). Plus, our 12V 400Ah lithium-ion battery weighs 86.2 lbs, only 1/3 the weight of a lead acid battery at the same capacity. Besides, our lithium battery case is IP65-level waterproof, and you can move it by grabbing the handles on both sides, which will set you free from worrying to install indoors or outdoors.

【100% Protection from 250A BMS】 LiTime 12V 400Ah LiFePO4 battery has built-in 250A BMS (Battery Management System) to protect it from overcharge, over-discharge, over-current (250A), over temp (167 °F) and short circuit. Without memory effect, no matter what state the battery is, it can be used as soon as it is charged.

【3200W Power & Fast Charging】 With a 3200W high load power, our 12V 400Ah lithium battery is perfect for RV, marine, boat, fishing, camping, solar home, trolling motor, and off-grid applications. It can realize 100% SOC & DOD, providing astronomical boosts in lifetime compared with lead-acid batteries. A 12V 80A/40A lithium battery charger is recommended; the lithium battery will be fully charged within 5hrs/10hrs.

【Max. 1600Ah Expandable Capacity】12V400Ah LiFePO4 battery supports to be connected in series & parallel, and max. in 4S4P for a 51.2V 1600Ah battery system to get 51.2kW output power and 81.92kWh usable energy.

Are LiTime LiFePO4 batteries safe?

Are LiTime LiFePO4 batteries safe? Yes. LiFePO4 is an inherently safe chemistry and the most stable lithium-type battery on the market. LiTime lithium cells are UL certified for the highest safety and sustainability standards. All LiTime LiFePO4 batteries come with an internal Battery Management System which protects against under-voltage during discharge, over-voltage during charge, over-current during discharge, over-temperature during charge and discharge, and short-circuit protection – protects battery cells from damage. Additionally, LiTime LiFePO4 Lithium batteries have been tested to be free from the risk of fire, and electric shock in harsh environments.

Can I use LiTime LiFePO4 Lithium batteries as starting batteries?

No. LiTime LiFePO4 lithium batteries are not intended to be used as starting batteries but energy storage, please do not use them to start any devices.

For more information to tell the differeces among these 2 types batteries, read on our blog Deep Cycle VS Starting Battery.

Can I charge LiTime lithium batteries with solar panels?

Yes, you can charge LiTime lithium batteries with solar panels. Here are 3 reliable ways to charge

1. Using Solar Panels

The LiTime 12V 400Ah battery can be fully charged by in one day (with effective sunshine 4.5hrs/day) by 1200W solar panels. It may take more than one day to fully charge the battery by ≥1200W solar panels since the duration and intensity of light would be a great factor for their charging efficiency.

2. Generator/Alternator

If the alternator or generator supports DC output, a DC-to-DC charger is needed to connect the battery to the generator; if your alternator or generator supports AC output, please add a suitable battery charger to connect the battery and the generator according to our recommendations.

The Recommended Charging Voltage: 14.2V - 14.6V. The Recommended Charging Current: ① 80A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 200A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.

3. LiFePO4 Smart Chargers

To charge 12V battery, it is recommended to use 14.6V battery charger.

The Recommended Charging Voltage: 14.2V - 14.6V.

The Recommended Charging Current: ① 80A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 200A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.

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

LiFePO4 batteries can safely charge between 32°F to 113°F (0°C to 45°C). LiTime 12V 100Ah TM & 230Ah LiFePO4 batteries include low-temperature charging protection which will automatically cut the battery charging off when the cell temperature is lower than 32℉, thus preventing the battery cells from damage when charging under the freezing point.

How do I store LiTime LiFePO4 lithium batteries?

It is recommended to store LiTime LiFePO4 batteries at 50% state of charge (SOC). If the batteries are stored for long periods, cycle the batteries at least every 3 months. Recommended storage environment: 10℃～35℃ (50℉～95℉), 45%RH～75％RH

What is the typical application for a 12V 400Ah lithium battery?

Typical applications include RVs, marine vessels, solar home energy storage, off-grid power systems and industrial equipment.

Can this battery be used in series to build a 48-volt system？

Yes. LiTime 12V deep cycle lithium batteries can be connected 4 in sereis to create a 48V battery system.

Note: DO NOT connect batteries with different chemistries in sereis or parallel.

Fairly light weight at 80 lbs. Only took about a day to fully charge with solar panels, and it runs my 3000 W inverter with no issues. 400ah is well worth getting instead of 4-100ah batteries connected together due to less wiring and possible loose connections. Highly recommend.

400 Ah Battery

The battery is great. I am having some problems connecting to the Bluetooth. There doesn't appear to be a QR code that came with the battery.

LiTime 12V 400Ah LiFePO4 Lithium Battery with 250A BMS, 5120Wh Usable Energy

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.

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’ve been using the battery primarily as an emergency power backup at home — it gives me peace of mind knowing I’ve got reliable energy if the grid goes down.

Fish Big

The lightweight design is a game-changer for someone like me, who spends a lot of time outdoors. I use this battery regularly to power all my electronics during trips, and it has never let me down.

Esther Snow

Drop in for our travel trailer Great addition to our travel trailer. Now we can spend endless time at a remote campsite without worrying we will run out of power.

James

Omg awesome! Things are looking great so far. With all the great reviews on the web. I’m feeling pretty good about the two 200 AH batteries I bought. Thank you for a great product
