LiTime 12V 140Ah Bluetooth Lithium Battery for RV and Trolling Motor

Yes, LiFePO4 is a chemistry known for its inherent safety and stability, making it the most reliable lithium-based battery available. LiTime lithium cells are certified by UL, FCC, CE, RoHS, and UN38.3, ensuring their quality and safety. Each LiTime LiFePO4 battery is equipped with an internal Battery Management System (BMS) that provides protection against under-voltage during discharge, over-voltage during charging, over-current during discharge, over-temperature during both charge and discharge, and short-circuit incidents, safeguarding the battery cells from damage. Furthermore, LiTime LiFePO4 lithium batteries have been rigorously tested and are free from fire hazards.

When you receive your new battery, it might arrive with a low state of charge (SOC) due to transport and storage. To ensure optimal performance, it's important to charge the battery right away to prevent over-discharge.

If your battery features Bluetooth functionality, like 12V 140Ah lithium battery, it may come powered off, displaying a terminal voltage between 3V and 5V, which means you won't be able to connect it to your phone. This shipping method helps minimize self-discharge and prolongs the battery's lifespan, similar to how mobile phones are shipped.

To resolve this issue, you can use one of two methods: either an AC-DC lithium battery charger or an MPPT solar charge controller. Simply charge the battery for 3 to 10 seconds to enable normal usage.

If you plan to store the battery for an extended period, charge it to a SOC of 50% and perform maintenance checks every three months. This practice will help maintain its functionality and performance.

The LiTime 12V 140Ah battery can be charged in three different ways:

1. Solar Panels andController

· Recommended Solar Power: >600W

o The battery can be fully charged in one day with 600W solar panels, assuming effective sunlight for about 4.5 hours.

o Charging may take longer than one day if sunlight duration or intensity is less than optimal.

· Recommended Charging Current:

o 28A (0.2C): Fully charges the battery in approximately 5 hours.

o 70A (0.5C): Fully charges the battery in about 2 hours.

· Charging Mode: 12V (14.6V) LI (LiFePO4)

2. Battery Charger

· Use a lithium iron phosphate (LiFePO4) battery charger to maximize capacity.

· Recommended Charging Voltage: Between 14.2V and 14.6V

· Recommended Charging Current:

o 28A (0.2C): Fully charges the battery in approximately 5 hours.

o 70A (0.5C): Fully charges the battery in about 2 hours.

Tip: It’s advisable to disconnect the charger from the battery once charging is complete.

3. Alternator/Generator

The LiTime battery can also be charged using an alternator or generator.

o If the alternator/generator supports DC output, a DC-to-DC charger should be placed between the battery and the generator.

o If it supports AC output, refer to the "Battery Charger" section above for appropriate charger recommendations.

· Recommended Charging Voltage: Between 14.2V and 14.6V

· Recommended Charging Current:

o 28A (0.2C): Fully charges the battery in approximately 5 hours.

o 70A (0.5C): Fully charges the battery in about 2 hours.

By utilizing these charging methods, you can efficiently maintain the performance and longevity of your LiTime 12V 140Ah battery.

No. As a kind of deep cycle battery, please DO NOT use it as a starter battery for any type of vehicle, suchas cars, motorbikes, tractors, etc.

For marine starting using, please visit LiTime Marine Starting Batteries.

Yes, LiTime lithium-ion LiFePO4 deep cycle batteries are rated IP65 for waterproof protection. This rating ensures they are resistant to dust and water spray, making them suitable for marine environments.

However, for optimal long-term protection, it is recommended to install the battery inside the cabin of the boat or in a dedicated battery box when used in marine applications.

Yes, the 12V 140Ah lithium battery supports a maximum configuration of 4 in series and 4 in parallel, allowing for a 48V 560Ah energy system that offers more power than a 48V 400Ah setup.

With a capacity of 28.6kWh, you can enjoy long-lasting energy for essential appliances—run your fan, fridge, and TV with ease, or power high-demand devices like washing machines, microwaves, and air conditioners without interruptions. This makes it ideal for home storage systems and off-grid living, ensuring that your power needs are always met.

Note: To connect batteries in series or parallel, they must meet the following conditions:

• They should be identical batteries with the same capacity (Ah) and battery management system (BMS) rating (A).
• They must be from the same brand, as lithium batteries from different brands have unique BMS configurations.
• They should be purchased within a close timeframe (ideally within one month).
