The 12V 100Ah deep cycle group 24 smart lithium battery, equipped with an integrated Bluetooth module, enables convenient monitoring of the battery status using your smartphone through the LiTime App.

Please charge the Bluetooth battery first after receiving it. This will ensure that the battery can be turned on and the Bluetooth connection is established.  (Our Bluetooth batteries are delivered in the off state, the virtual voltage of the battery terminal is 3V-5V, this is a normal phenomenon, just use the AC-DC charger or MPPT to charge the battery and turn on the battery, it can be used normally.)

If you intend to store the battery for an extended period without use, we recommend charging it to a SOC 50% and conducting maintenance every three months. These measures will help preserve its functionality and performance in the long run.

Yes, this battery has low-temperature charging-off protection. It's recommend to charge the battery during the temperature range: 0℃ to 50℃ / 32℉ to 122℉.

The 12V lithium battery from LiTime supports maximum connections of 4 in series and 4 in parallel. Allow you to build up a maximum battery system of 16 battery units with 20.48kWh Max. capacity and 20.48kW of Max. power.

Note: To connect in series or /and parallel, batteries should meet the below conditions:

a. identical batteries with the same battery capacity (Ah) and BMS (A);

b. from the same brand (as lithium battery from different brands has their special BMS);

c. purchased in near time (within one month)

1. Using Solar Panels

The battery can be fully charged in one day (with effective sunshine 4.5 hrs/day) by 400W solar panels. It may take more than one day to fully charge the battery by ≥400W 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 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 main difference between a LiTime Group 24 and Group 31 battery lies in their physical size. Group 24 batteries are generally smaller compared to Group 31 batteries.

We recommend mounting it upright with the poles facing up. It is important to pay attention that the front and top are not facing down.
