LiFePO4 Battery Charger

FAQS

Q:Why can't I use lead-acid battery charger to charge lithium batteries?

Lithium chargers utilize the CV/CC (constant voltage/constant current) charging algorithm. This method limits the current to a set level until the battery reaches the desired voltage. As the battery approaches maximum capacity, the current gradually decreases. This system allows for fast charging while preventing overcharging, making it ideal for lithium-ion batteries.

In contrast, standard chargers usually do not employ the CV/CC method. Using a lead-acid battery charger on lithium batteries may result in incomplete charging or even cause damage to the lithium cells.

Q: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.

Q: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.

Q: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 a BMS 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.

Q:Do LiTime lithium battery chargers have protection?

Yes. LiTime LiFePO4 lithium battery chargers are featured with BMS to protect the battery from over-temperature, reverse polarity, short circuit, and over-voltage.

What's more, LiTime LiFePO4 Lithium battery chargers have 0V function, which can jump start the dead lithium batteries.
