LiTime 36V Lithium LiFePO4 Batteries for Golf Cart & Marine

What is the lifespan of a LiTime 36V LiFePO4 battery?

LiTime 36V LiFePO4 batteries can last over 4,000 cycles at 100% depth of discharge, which translates to more than 10 years of regular use under ideal conditions.

Can multiple 36V LiFePO4 batteries be connected in parallel or series?

LiTime’s 36V batteries are designed for parallel connections to increase capacity.

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).

Are LiTime LiFePO4 Lithium batteries safe?

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.

Is it OK to charge LiFePO4 to 100%?

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.

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 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 protection machanisms 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 LiFePO4 lithium battery 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.

What should I do when you get a new battery?

When receiving 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 to charge the LiTime LiFePO4 36V lithium batteries?

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.
