12V 15A LiFePO4 Battery Charger Features:

1. Superior Safety: Lithium Iron Phosphate chemistry eliminates the risk of explosion or combustion due to high impact overcharging or short circuit situation.
2. High power: Delivers twice power of lead acid battery, even high discharge rate, while maintaining high energy capacity wider temperature range: -20℃~60℃.
3. Long cycle life: offers up to 20 times longer cycle life and 5 times longer/calendar life the lead acid battery, helping to minimize replacement cost and reduce total cost of ownership.
4. Lighter weight: About 40% of the weight of a comparable lead acid battery. A “dron in”replacement for lead acid batteries.
5. Superior Safety: Lithium Iron Phosphate chemistry eliminates the risk of explosion or combustion due to high impact, overcharging or short circuit situation.
6. Increased Flexibility: Modular Design enables deployment of up to up to ten battery in parallel.
7. Energy density is high. The volume and weight of lithium battery is 1/3 to 1/4 of the traditional lead acid battery with the same capacity.

Input Characteristics:

Input Voltage: 110/230V AC

Input Frequency: 50Hz or 60Hz and single phase.

Efficiency: ≥85.0% @230Vac/50Hz(Typical full load)

Input socket: EU/AU/UK/US/Italy/India customized

Charging Characteristics:

Pre-charging step: start with small current (often set 20% of CC 3A) to protect over discharged battery.

Constant Current (CC) step: charge with max 15A current for fast charging purpose.

Constant Voltage (CV) step: charging current begins to drop from max 15A and voltage reached max set 14.4V or 14.6V or 14.7V.

Floating step: voltage goes to set 13.5V or 13.8V and charging with small current, often set 20% of CC, till to fully charged.

Protection for 12V 15A LiFePO4 battery charger

Over Voltage Protection: The battery charger will be auto recovered when faults remove.

Over Current Protection: Charger output current does not exceed the set maximum battery charging current.

Over Short Circuit Protection: Battery charger output can be shorted without damage No odor, smoke, fire, plastic deformation, and excessive heal happen. The power shall be auto-recovery. (It will enter into normal condition when then the fault condition is removed)

Over reverse polarity Protection: When the battery charger output terminals reversed after the charger will not work until it’s connected correctly.
