FAQ
Q: Are LANPWR LiFePO4 Lithium batteries safe?
A: Yes. LiFePO4 is an inherently safe chemistry and the most stable lithium-type battery on the market. LANPWR lithium cells are CE certified for the highest safety and sustainability standards. All LANPWR 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, LANPWR LiFePO4 Lithium batteries have been tested to be free from the risk of fire, and electric shock in harsh environments.
Q: Can I use LANPWR LiFePO4 Lithium batteries as starting batteries?
A: No. LANPWR LiFePO4 lithium batteries are not intended to be used as starting batteries but energy storage, please do not use them to start any devices. We also sell starting batteries. If necessary, please contact customer service to obtain the purchase address.
Q: What is a group 31 battery?
A: The group 31 batteries is the most popular battery size, measuring approximately L330.20* W172.72* H239.78 mm, which is widely used in boats, RVs, home storage, and off-grid. LANPWR 12V 100Ah deep cycle LiFePO4 battery measures L329* W172* H214 mm. It is a perfect replacement for group 31 batteries.
Q: How many amp hours does a group 31 battery have?
A: LANPWR 12V 100Ah lithium battery is a powerful replacement for group 31 batteries due to its larger capacity than traditional AGM or Lead Acid group 31 batteries. It has a 100Ah capacity and 1280Wh energy, leaving you peace of mind to handle various situations.
Q: How much does a group 31 battery weigh?
A: Being the utmost replacement for the group 31 batteries, LANPWR 12V 100Ah deep cycle LiFePO4 battery, weighing 24.25 lbs, is 1/5 the weight of a 12V 200Ah lead acid battery (about 130lbs) but equivalent in energy.
Q: Do you have battery box for group 31?
A: Yes, LANPWR has a portable battery box for group 31. Built in voltmeter, it can be used for marine & RV, fitting for group size 24 battery, group 27 battery size and group 31 battery size.
Q: Can I charge LANPWR LiFePO4 Lithium batteries with solar panels?
A: Yes, you can charge LANPWR LiFePO4 lithium batteries with solar panels. You should size your charge controller based on the voltage and current output of your solar array setup. That will ensure that your charge controller can process and regulate the power coming from your solar panels. Take a 24V MAX. 22 amps output solar system as an example, you need a solar charge controller that can handle 24 volts and 27.5 amps (125% of your max current output).
Q: Can I charge LANPWR LiFePO4 lithium batteries in cold weather (under freezing temperatures)?
A: The LANPWR 12V 100Ah LiFePO4 batteries can be safely charged between 32°F to 113°F (0°C to 45°C). But when charging under the freezing point, the battery cells may be damaged.
Q: How do I store LANPWR LiFePO4 lithium batteries?
A: It is recommended to store LANPWR LiFePO4 batteries at 50% state of charge (SOC). If the batteries are stored for long periods, cycle the batteries at least every 6 months. Recommended storage environment: 10℃～35℃ (50℉～95℉），45%RH～75％RH.
Q: How long to charge LANPWR LiFePO4 lithium batteries?
A: Write content to answer to common questions your customers may have about your products, shipping policies.
Q: What is the maximum number of LANPWR 12V 100Ah lithium batteries connected in series or parallel?
A: The maximum number of connecting LANPWR 12V 100Ah lithium batteries in series or parallel is 4 (4S or 4P). Please notice that the LANPWR lithium batteries can ONLY be connected in series or parallel with the same brand (LANPWR), same type (lithium), same voltage (V), same capacity (Ah), same BMS and similar purchasing date (within 3 months).
Q: What is the maximum discharge capacity of a LANPWR 12V 100Ah lithium battery?
A: The LANPWR 12V 100Ah LiFePO4 lithium battery has a maximum continuous discharge of 100Ah and a maximum discharge of 280Ah for 5 seconds.
