Hot LiTime 12V 100Ah Group 24 Bluetooth Lithium Deep Cycle Battery

The group 24 battery smart battery built-in Bluetooth feature lets you monitor your battery's real-time status—including state of charge (SOC), voltage, current, cycle life, and temperature—directly from your smartphone. Just download the LiTime Battery App, enable Bluetooth on your phone, and select your battery from the list of available devices. No extra hardware is needed.

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 solar charge controller to charge the battery and turn on the battery, it can be used normally.)

Note: When charging the Bluetooth batteries for the first time, the power level may stay at 99% for several hours before reaching 100%.

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 group 24 battery has low-temperature charging-off protection. It's recommend to charge the battery during the temperature range: 0℃ to 50℃ / 32℉ to 122℉.

For optimal performance, charge the battery indoors on cold days. To explore more options for winter off-grid power, check out our LiTime Cold Weather Batteries.

You can easily expand your power system using LiTime Group 24 batteries by connecting them in various configurations.

• Series Connection: Connect up to 4 batteries to increase voltage to 48V.
• Parallel Connection: Connect up to 4 batteries to increase capacity to 400Ah.
• Series-Parallel Connection: Build a larger bank of up to 16 batteries (for example, a 4-series and 4-parallel, or 4S4P, setup).

Important Rules for Connecting Batteries

For your system to operate safely and perform optimally, all connected batteries must meet the following criteria:

• Same Specifications: They must have the identical capacity (Ah) and BMS (Battery Management System) current rating (A).
• Same Brand: Only connect LiTime batteries with other LiTime batteries. Different brands often have incompatible BMS programming, which can lead to system failure.
• Purchased Recently: All batteries should be purchased within a short timeframe (ideally one month) to ensure they are from a similar manufacturing batch and have balanced internal characteristics.

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.

Install the battery upright with post bolt facing up, and it could notbe mounted upside down. lf you need to mount the battery at its side. Please contact [email protected] to confirm the direction.

This Group 24 bluetooth battery is designed for a wide temperature range: it can be charged between 32 °F and 122 °F (0–50 °C) and discharged between –4 °F and 140 °F (–20–60 °C). For hot Arizona conditions, avoid charging the battery if its temperature exceeds 122 °F, keep it shaded and well‑ventilated, and use the LiTime Bluetooth app to monitor battery temperature and status; the built‑in BMS also provides over‑temperature protection to help safeguard performance.
