Ionic Lithium LiFePO4 12V 4A Charger

LithiumHub chargers are smart chargers that work with our lithium-ion batteries. The chargers provide a constant current and voltage and stop charging once it reaches 14 volts. It's designed to maximize the life of your lithium battery.

12V LiFePO 4A charger works with any of our batteries up to 30 Ah and will work with lead-acid as well.

For safety reasons, the charger times out and stops charging after 72 hours of continuous use. This is indicated by blinking red LEDs. To activate the charger again, simply disconnect and reconnect the power cable.

Product Description

Ionic Deep Cycle 12V20-EP

World Class Safety Features

Ionic Deep Cycle 12V20-EP Lithium Battery has 12 volts and a 20Ah capacity and is perfect for powering your deep cycle systems. Ionic Deep Cycle has an internal microprocessor controlled battery management system (BMS) that monitors the key operational parameters during charging and discharging, such as voltages, currents and internal temperatures. Ionic Deep Cycle Batteries can be hooked up 4 in series and as many needed in parallel.

Built for Long Lasting Reliable Power

The Ionic Deep Cycle Battery has a cycle life of 3,000 cycles or about 10 calendar years. Our lithium-ion batteries have a usable capacity of 99% compared to 50-60% for traditional lead-acid batteries]. LithiumHub Deep Cycle batteries function in the widest range of temperatures with a discharge temperature range (Functional) of –20°C to 60°C (–4°F to 140°F) and a charge temperature range of 0°C to 45°C (32°F to 113°F). Automatically detects if batteries are too cold to take a charge.

The Ionic Deep Cycle line has the best weight to power ratio on the market

At 3.0” (L) x 7.0″ (W) x 6.5” (H) and weighing only 6.6 lbs., the Ionic Deep Cycle 12V20-EP has the best size to power ratio of any deep cycle battery on the market. Connectors: M6 screws allow the battery to be installed in any direction unlike lead-acid batteries which are fixed. Ionic Deep Cycle Batteries self-discharge rate per month is between 1-3% compared to lead-acid batteries which are about 30%. Max charge voltage is 14.6V and the discharge cut-off voltage is 10.5V. Max charge current is 10A and max discharge current is 20A / 80A(3s). Can be charged with solar chargers. Can be charged with most traditional lead-acid chargers that do not have “Desulfate” mode, provided the current levels do not exceed lithium battery charge specification. Using a traditional lead-acid charger that reaches 14.4-14.6 volts will allow the battery to be fully charged. Chargers that do not exceed 13.6 volts will only charge the battery to 50% capacity or less.

Great product and great service

The batteries are great! They are light,long lasting, and I like how I can check them throughout the day on the app. This is my third battery ( two for trolling motor last year) and I’ve called a few times with questions and they have always helped and been easy to work with. Thanks
