LiFePO4 Battery Charger 12V 62A — Fast Charging for Lithium Iron Phosphate Battery Banks

Fast, Safe Charging for LiFePO4 Batteries.

Charging a LiFePO4 battery with the wrong charger is one of the most common mistakes in off-grid system builds — lead-acid chargers use the wrong voltage profile and will either undercharge the battery or damage it over time. This dedicated 12V 62A LiFePO4 charger uses the correct charge profile for lithium iron phosphate chemistry, delivering fast, safe charging that maximizes both charge speed and battery longevity.

Features

• 12V LiFePO4 charge profile — correct voltage and current profile for lithium iron phosphate batteries; not compatible with lead-acid chemistry
• 62A output current — high-current output for fast charging of large battery banks; charges a 100Ah battery in approximately 1.5–2 hours
• Automatic charge stages — bulk, absorption, and float stages optimized for LiFePO4 chemistry
• LED status indicators — shows charging stage and completion status at a glance
• Built-in protection — over-voltage, over-current, over-temperature, and reverse polarity protection
• Cooling fan — temperature-controlled fan maintains safe operating temperature during high-current charging
• Wide AC input range — 110V/220V compatible for use in the US and internationally
• Durable construction — metal housing for heat dissipation and long-term reliability

Who It’s For

• Off-grid solar system builders who need a fast, dedicated LiFePO4 charger
• RV and van lifers who want to quickly recharge their LiFePO4 battery bank from shore power
• Marine users who need a reliable LiFePO4 charger for boat battery systems
• Anyone who needs to charge a 12V LiFePO4 battery bank quickly and safely

How to Use

1. Connect the charger’s positive output lead to the battery’s positive terminal.
2. Connect the negative output lead to the battery’s negative terminal.
3. Plug the charger into a 110V or 220V AC outlet.
4. The charger will automatically begin the bulk charge phase and progress through absorption to completion.
5. LED indicators show the current charging stage and completion status.
6. Disconnect after charging is complete — the charger will stop automatically, but disconnecting when not in use is good practice.

Frequently Asked Questions

Can I use this on a lead-acid battery?
No — this charger is specifically designed for LiFePO4 chemistry. Using it on a lead-acid battery may overcharge and damage the battery. Use a charger with the correct profile for your battery chemistry.

How fast will it charge my battery?
At 62A, it charges a 100Ah battery in approximately 1.5–2 hours from empty. A 200Ah battery takes approximately 3–4 hours. Actual time varies based on starting state of charge and battery temperature.

Is it safe to leave connected after charging is complete?
The charger stops delivering current when the battery is full. However, disconnecting when not in use is recommended to prevent any parasitic draw and extend the charger’s service life.
