Litime 80A 12V LiFePO4 Battery Charger — Fast 80 Amp AC-DC Smart Charger with Cooling Fan

The LiTime 80 Amp 12V LiFePO4 Battery Charger is a high-current AC-DC smart charger that rapidly and safely charges 12.6–14.6V lithium iron phosphate batteries with built-in protection and active cooling.

This compact, aluminum-housed charger delivers up to 80A of charging current for 12V LiFePO4 battery banks used in RVs, off-grid systems, backup power and solar storage. It combines a 3-stage charging algorithm with 0V activation for deeply discharged cells, LED status indicators for simple monitoring, and a cooling fan to sustain performance under heavy loads. Safety features and regulatory testing make it a practical choice when you need fast, reliable charging for modern lithium batteries.

How fast will this charger refill my 12V LiFePO4 battery?

The LiTime 80A charger supplies up to 80 amps in its constant-current stage, significantly reducing recharge time compared with lower-amp chargers. Actual time depends on battery capacity, state of charge and BMS restrictions, but large battery banks that take many hours on trickle chargers can often be replenished in a fraction of that time.

• Max output: 80A continuous for rapid replenishment
• Charge stages: Pre-charge, Constant Current (CC), Constant Voltage (CV)
• Target float: 14.6V tailored for LiFePO4 chemistry
• 0V activation: revives deeply discharged batteries protected by BMS

Is it safe to use with my LiFePO4 battery and battery management system?

Yes — this charger uses a 3-stage charging profile designed for LiFePO4 cells and includes multiple hardware protections to cooperate with typical BMS behavior. Built-in safeguards reduce the risk of over-voltage, over-current, reverse polarity and short circuits, while thermal management helps prevent overheating during heavy use.

• Protections: over-temp, over-voltage, over-current, short-circuit, reverse polarity
• Standards: FCC, CE, RoHS tested for compliance
• Active cooling: internal fan plus aluminum housing for heat dissipation
• Compatible with BMS: supports activation and controlled CV termination

How do I connect and monitor the charger during operation?

Connections are straightforward: AC mains input connects to the charger and the DC output uses an Anderson-style connector for a secure battery hookup. LED indicators display charging status at a glance, and the robust aluminum case and fan make the unit suitable for installation where ventilation is available.

• Output connector: Anderson plug for reliable DC connection
• Indicators: multi-color LEDs for charge stage and status
• Mounting: durable aluminum housing for fixed installation
• Installation note: not waterproof—avoid marine or exposed outdoor mounting

Who this charger is for: If you manage 12V LiFePO4 battery banks in motorhomes, solar-plus-storage systems, workshop UPS setups or residential backup circuits and you need fast, repeatable charging with built-in safety, the LiTime 80A charger is designed for you. It is not intended for marine use or environments that expose equipment to water. Choose this model when you want faster recharge cycles, BMS-compatible activation for deeply discharged packs, and a unit that prioritizes heat control and regulatory compliance.
