LiTime 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.

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, LiTime 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.

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 0°C to 50°C (32°F to 122°F). 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, recharge 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 12V 10Ah or 12V 20Ah charger, and a full charge will take 10 hours and 5 hours respectively.
