Temgo 14.6V 20A Lithium Battery Charger-Smart and Efficient for LiFePO4 Batteries
Designed for use with 12V LiFePO4 batteries, the Temgo 14.6V 20A Lithium Battery Charger offers fast charging (100Ah battery fully charged in about 5 hours), greater safety and longer battery life.
Crafted by Temgo, this charger features advanced technology, built-in LED indicator lights and low-temperature protection to combat slow charging, battery wear and safety risks. Whether you are using 12V RV or marine lithium batteries, this charger will ensure your batteries always have enough power to run.
Stable Charging Operation To Avoid Affecting The Life Of Lithium Batteries
The Temgo 14.6V 20A Li-ion battery charger provides a stable 20A output current, which can fully charge a 100Ah lithium iron phosphate battery in about 5 hours, 30% faster than a standard 10A Li-ion battery charger.
A 200Ah battery will charge in approximately 10 hours, a 300Ah battery will charge in approximately 15 hours and a 460Ah battery will charge in approximately 23 hours (Please note: charging times may vary if the battery's BMS is limiting current).
Its three-stage intelligent charging (pre-charge, fast charge, constant voltage charge) ensures 100% full charge and prevents overcharging, thereby extending the battery life by up to 20%. This means less downtime for your RV travel or solar system.
Compact, Portable, Durable Design
Weighing only 2.87 LBs (1.3 kg) and measuring 7.99*3.94*2.12 In, this charger fits easily into the cabin of your RV. Its aluminum housing and cooling fan ensure reliable heat dissipation, extending the battery's durability during long-term use. High-quality Anderson connectors, AC power cords, and alligator clips simplify charging installation and use in RVs or off-grid systems.
Comprehensive Intelligent Charging Protection
The charger is equipped with short circuit protection, reverse polarity protection, overvoltage protection, and overtemperature protection to prevent expensive battery damage caused by wiring errors, electrical failures, or overheating. These features ensure that you can charge safely whether you are charging RV lithium batteries or in outdoor sailing environments.
Low Temperature Protection For Cold Environments
When your lithium battery is charged in cold weather, the Temgo 14.6V 20A charger has a low temperature protection function that automatically adjusts the charging process to protect your battery from damage as low as 14°F (-10°C). This prevents the battery from being damaged by freezing temperatures and ensures that the battery can be charged with a safe and efficient voltage.
Optimized for 12V LiFePO4 Batteries
Designed specifically for 12V (14.6V) LiFePO4 batteries, this charger provides precise voltage charging control. Its smart technology adjusts the state of charge to protect your battery, maximize battery life and improve performance. Unlike generic chargers that risk under or over charging, Temgo is the best lithium battery charger choice for RV, marine and off-grid home solar who are looking for a reliable battery charger.
How to Use the Temgo 14.6V 20A Lithium Battery Charger
a. Connect the Battery: Connect the positive (red) and negative (black) alligator clips or Anderson connectors to the battery terminals.
b. Plug Into AC Power: Connect the 4.6-foot AC power cord to the charger and plug into a 100-240V AC outlet.
c. Monitor Charging Status: View real-time voltage, current, and status on the Li-Ion Battery LCD display, or observe the Charger LED Indicator:
• Green Flashing: Not Connected
• Blue On: Charging
• Green On: Fully Charged
• Red Flashing: Error/Protection Mode
Three-Stage Charging Process
Pre-Charge (T1): Gently activates low-voltage batteries and reconditions them to extend their life, ideal for restoring battery power after a long RV trip.
Fast Charge (T2): Provides a constant 20A current for fast charging, quickly reaching full capacity, ideal for solar or marine use.
Constant Voltage Charging (T3): Maintains a steady 14.6V voltage, prevents overcharging, and automatically shuts off to protect your battery.
