48V LiFePO4 Lithium Battery

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.

The 51.2V LiFePO4 Battery Is a kind of powerful battery designed to replace lead-acid battery.

Our 51.2V LiFePO4 battery is commonly called a "48V" battery to align with standard terminology in the industry. Many customers and applications have long used 48V lead-acid batteries, so maintaining this naming convention helps with easier understanding and compatibility.

Technically, the battery’s nominal voltage is 51.2V, reflecting the true voltage output of lithium iron phosphate (LiFePO4) cells, which operate at 3.2V per cell. By keeping the "48V" label, customers familiar with traditional 48V setups can seamlessly upgrade to lithium technology, enjoying the benefits of higher capacity, longer life, and more consistent performance without confusion about compatibility.

So while our battery may be called "48V," rest assured it’s engineered for more powerful and efficient output, making it the ideal replacement for conventional lead-acid systems in any 48V-compatible application.

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.

LiTime's 48V 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.

Yes, these batteries are compatible with solar setups. For best performance, use an MPPT solar charge controller designed for lithium batteries to maximize charging efficiency.

Yes, these batteries are well-suited for golf carts, providing a steady, reliable power source without the maintenance or risk of acid spills associated with lead-acid batteries.

Yes, multiple 48V LiFePO4 batteries can be connected in parallel to increase the overall capacity, although series connections to increase voltage are not recommended for these batteries.

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).

Yes. LiFePO4 is an inherently safe chemistry and the most stable lithium-type battery on the market. LiTime lithium cells are certificated by UL, FCC, CE, RoHS, and UN38.3 to ensure their quality and safety.

All LiTime LiFePO4 batteries come with an internal Battery Management System, which protects against under-voltage during discharge, over-voltage during charge, over-current during discharge, over-temperature during charge and discharge, and short-circuit protection – protects battery cells from damage. Additionally, LiTime LiFePO4 Lithium batteries have been tested to be free from the risk of fire.

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.

Yes, LiTime LiFePO4 batteries can be charged to 100%. 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.

Due to the different charging requirements compared to lead-acid batteries, we recommend using a  LiFePO4 lithium battery charger for charging.

Here are the charging options for LiTime lithium golf cart batteries:

1)AC-DC lithium battery charger: Choose a charger with the correct charging voltage to safely charge the battery.

2) Solar panels: When using solar panels, ensure you connect a  solar charge controller for safe charging.

3) Alternator/Generator:

a. If your alternator or generator supports DC output, a DC-to-DC charger is needed to connect the battery.

b. If your alternator or generator supports AC output, use a compatible battery charger as recommended in the product manual to safely connect the battery and generator.
