Hot LiTime 12V 100Ah Group 27 Bluetooth Deep Cycle Lithium Battery

The main difference between LiTime Group 27 and Group 31 battery lies in their physical size. Group 27 batteries (12.13*6.69*8.31 in) are generally smaller compared to Group 31 batteries (13*6.77*8.43 inch), which is compatible with Group 27-31 battery boxes.

Its compact size is suitable for most RV types including the 2024 Brinkley Model Z 2900, Four Winds 22E and Forester. With 10% higher energy density compared to the 12V 100Ah Group31 battery, it delivers the same power in a more compact size, lightening the load on the RV, and making it easier to carry and travel.

Please charge the Group 27 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.

The 12V Group 27 lithium battery 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 battery 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.
