LiTime 12V 100Ah Lithium Deep Cycle Battery

Yes, LiFePO4 is an inherently safe chemistry and is regarded as the most stable type of lithium battery on the market. LiTime lithium cells are UL certified, adhering to the highest safety and sustainability standards. All LiTime LiFePO4 batteries come equipped with an internal Battery Management System that protects against under-voltage during discharge, over-voltage during charge, over-current during discharge, over-temperature during both charge and discharge, and short-circuit events, ensuring the safety of the battery cells. Additionally, LiTime LiFePO4 batteries have been rigorously tested to confirm that they pose no risk of fire or electric shock, even in challenging environments.

No, LiTime LiFePO4 lithium batteries are intended for energy storage, not for use as starting batteries. Please do not use them to start any devices.

The group 31 batteries is the most popular battery size, measuring approximately L13* W6.8* H9.44 inch, which is widely used in boats, RVs, home storage, and off-grid. LiTime 12V 100Ah deep cycle LiFePO4 battery measures L13* W6.77* H8.43 inch. It is a perfect replacement for group 31 batteries.

The LiTime 12V 100Ah lithium battery is a powerful alternative to Group 31 batteries, delivering substantially higher capacity than traditional AGM or lead-acid options. With a 100Ah capacity and 1280Wh of energy, it ensures dependable performance across a range of applications, providing peace of mind in any situation.

Being the utmost replacement for the group 31 batteries, LiTime 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.

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

1. Using Solar Panels

The battery can be fully charged in one day (with effective sunshine 4.5 hrs/day) by 300W solar panels. It may take more than one day to fully charge the battery by ≥300W solar panels since the duration and intensity of light would be a great factor for their charging efficiency.

Besides solar panels, there are 2 more ways to charge.

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 20A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 50A (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 20A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 50A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.

The LiTime 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.

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

You can charge our LiTime 12V 100Ah lithium battery with a 12v10Ah or 12v20Ah charger, and a full charge will take 10 hours and 5 hours respectively.

The maximum number of connecting LiTime 12V 100Ah lithium batteries in series or parallel is 4 (4S or 4P). Please notice that the LiTime lithium batteries can ONLY be connected in series or parallel with the same brand (LiTime), same type (lithium), same voltage (V), same capacity (Ah), same BMS and similar purchasing date (within 3-6 months).

The LiTime 12V 100Ah LiFePO4 lithium battery has a maximum continuous discharge of 100Ah and a maximum discharge of 280Ah for 5 seconds.
