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 LiFePO4 lithium batteries with solar panels?

Yes, you can charge LiTime LiFePO4 lithium batteries with solar panels.  Here are 3 recommended ways to charge LiFePO4 lithium batteries.

1. Using Solar Panels

The LiTime 12V 300Ah 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 60A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 150A (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 lithium 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.

Related reading: What is low-temperature protection to lithium batteries?

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.

How many LiTime 12V 300Ah lithium Batteries can I connect at most?

He 12V sereis batteries support versatile connections, including series, parallel, and series-parallel
connection. You can connect 12V 300Ah up to 4 batteries in series, 4 in parallel, or 16 in the series-parallel connection to create
40.96kW capacity and 61.44kWh energy.

Batteries of the same model and similar capacity are required.

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

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.
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.
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
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.
Installed 2 100ah batteries in boat as my house bank with the Litime DC to DC 40amp charger to protect alternator. I have to say very happy with everything.
