LiTime 24 Volt Deep Cycle LiFePO4 Lithium Battery

What are the benefits of using a 24V LiFePO4 battery over other types?

LiFePO4 batteries offer a longer lifespan, lighter weight, faster charging, and higher efficiency than traditional lead-acid batteries. They’re maintenance-free and provide a consistent power output.

What should you do when you receive a new battery?

When you receive your battery, it may have a low state of charge (SOC) due to transportation and storage. To ensure optimal performance, charge the battery immediately to avoid over-discharge.

Batteries with Bluetooth functionality may arrive in an off state, showing a terminal voltage between 3V and 5V, and you won't be able to connect them to your phone. This is because they are shipped powered off, similar to mobile phones, to minimize self-discharge and extend the battery's lifespan.

There are 2 ways to solve the problem: using an AC-DC lithium battery charger or an MPPT solar charge controller to charge it for 3 to 10 seconds, then the battery can be used normally.

If you plan to store the battery for a long time, charge it to a SOC of 50% and perform maintenance every three months. This will help preserve its functionality and performance.

How many cycles can I expect from a 24V LiFePO4 battery?

LiTime's 24V LiFePO4 batteries are rated for 4,000 cycles at 100% depth of discharge, giving them an expected lifespan of around 10 years with regular use.

Are 24V LiFePO4 batteries suitable for use in RVs and marine applications?

Absolutely, these batteries are an excellent choice for RVs and marine use due to their durability, safety, and ability to provide consistent power without the risk of spillage or maintenance needs.

Can I connect multiple 24V LiFePO4 batteries together?

Yes, you can connect these batteries in series & parallel to increase capacity.

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).

Do LiFePO4 batteries require any maintenance?

LiFePO4 batteries are virtually maintenance-free. However, it's a good idea to periodically inspect the battery for any loose connections and store it in a cool, dry place if not in use for extended periods.

How to Charge LiTime 24V LiFePO4 lithium batteries?

Because LiFePO4 lithium batteries have different charging requirements than lead-acid batteries, we recommend using a LiFePO4 lithium battery charger.

Here are the charging options for LiTime lithium batteries:

1. AC-DC Lithium Battery Charger: Select a charger with the appropriate voltage to safely charge the battery.

2. Solar Panels: When using solar panels, always connect a solar charge controller to ensure safe charging.

3. Alternator/Generator:

DC Output: If your alternator or generator provides DC output, you will need a DC-to-DC charger to connect the battery.
AC Output: If it provides AC output, use a compatible battery charger as specified in the product manual to safely connect the battery and generator.

Is it OK to leave a LiFePO4 battery on the charger?

Although it is generally safe to leave a LiFePO4 battery on the charger, as both the charger and the battery itself have mechanisms to prevent overcharging, it’s still best to monitor the charging process.

Once the battery is fully charged, disconnecting it promptly is recommended to avoid unnecessary damage.

For convenience, LiTime offers chargers with Anderson connectors, allowing you to stop charging simply by unplugging the Anderson connector without needing to separate the battery terminals from the screws after charging.

However, for optimal safety, it’s advised to first unplug the AC plug before disconnecting the Anderson connector.

Is it bad to completely drain a LiFePO4 battery?

It is not recommended to fully discharge LiFePO4 batteries. Although these batteries can handle deep discharges better than lead-acid batteries, frequently discharging them to 0% can reduce their lifespan and performance. It's best to recharge the battery before it drops below a very low level, ideally at 20% or higher.

Is it OK to charge LiFePO4 to 100%?

Yes, LiTime LiFePO4 batteries can be charged to 100%. Unlike some other lithium battery chemistries, LiFePO4 batteries are designed to handle full charges without significant risk of damage. However, for optimal longevity, it’s often recommended to keep the battery's SOC between 20% and 80% for regular use.
