12V 3A LiFePO4 Battery Charger – Safe, Efficient Charging for Small Dakota Lithium Batteries

The 12V 3A LiFePO4 Battery Charger is the perfect charging solution for smaller lithium batteries under 25Ah. Specifically designed for Dakota Lithium batteries, this charger delivers safe, precise, and efficient power—protecting your investment and extending battery life.

Key Features:

  • LiFePO4 Compatible
    Engineered specifically for Dakota Lithium 12V LiFePO4 batteries, ensuring optimal charging performance and safety.

  • 3A Charging Power
    Delivers a steady 3 amps per hour, providing fast yet controlled charging for smaller-capacity batteries.

  • Ideal for Small Battery Packs
    Perfectly suited for 7Ah, 10Ah, and 18Ah batteries, making it a great choice for electronics, fish finders, mobility gear, and small backup systems.

  • Protects and Extends Battery Life
    Unlike lead-acid (SLA) chargers, this lithium-optimized unit prevents overcharging, undercharging, and battery damage—ensuring longer battery lifespan.

For larger batteries (≥25Ah), use the 10A charger for faster charging.

Specifications

For 12 volt lithium batteries
We highly reccomend you use a LiFePO4 compatible charger. 12v chargers for lead acid batteries may work, but will decrease performance and lifespan of the battery.

Charger rating
INPUT 100-240 volts, 50/60HZ. OUTPUT: 14.4 volts, 3.0 amps
Terminal ConnectionsAlligator clips for ease of use. Clip black to your black terminal. Red to your red terminal. Do not short circuit. Red light on the charger will turn on when charging. Light turns green when the battery is full.

Smart BMS Communication
Charger will restart or "wake up" a Dakota Lithium BMS that has turned off a battery due to short circuit or excessive amp draw. Simply connect the charger to the battery to initiate a restart.

How fast will my battery charge?
Choose a 3 amps. To determine your charging speed take the amp hour rating of your battery and divide by the amp rating of your charger. For example, a 3 amp charger would fully charge a 7 amp hour battery (Ah) in 2.3 hours.

Can I charge my battery faster?
For most applications a charging time of 3 - 10 hours provides the longest lifespan for your battery. But if you have an application where you need rapid charging Dakota Lithium batteries can be safely charged in up to 1 hour (at a rate of 1C). For example, you could use a 10 amp charger with a 10 Ah battery for a 1 hour charge time. Charging at a 1 hour rate does reduce the lifespan over time. In our laboratory testing we found that the longest lifespan for Dakota Lithium batteries was at a charging speed of 0.3C or less (we recommend that the charger amp rating is 1/3 or less of the battery amp hour rating for longest lifespan).

What voltage should LiFePO4 batteries be charged at?
14.4 volts is recommended for Dakota Lithium (LiFePO4) batteries. This charger charges at 14.4 volts.

What is the difference between a 3 amp and 10 amp charger?
The amp rating is how much energy goes into your battery in 1 hr. For example, a 10 amp charger will charge a 54 amp hour battery in 5.4 hours. An appropriate sized charger should be 1/3 of less the amp rating of your battery. For example, a 3 amp charger is perfect for a 10 amp hour (Ah) battery.
