Ionic Lithium Deep Cycle 12V12-EP

World Class Safety Features

Ionic Deep Cycle Lithium Battery 12V12-EP has 12 volts and a 12Ah 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 Batteries can be hooked up four 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 3.96” (L) x 5.91” (W) x 3.99” (H) and weighing only 3.5 lbs., the Ionic Lithium Deep Cycle 12V12-EP has the best size to power ratio of any deep cycle battery on the market. Connectors: F2, 0.25”, 6.4 mm Spade Terminals allow the battery to be installed in any direction unlike lead-acid batteries which are fixed. Ionic Lithium 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 10.5. Max charge current is 12A and max discharge current is 30A / 60A(3s). Peak discharge current is 60A(3s) with 360W continuous and 700W (3s) peak. 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.
Note:Limited to 150W battery output per battery. It will not work with motors over 150W for single 12V battery. 300W for two 12v at 24V or 450W for three 12v at 36v

    I am a guitarist and I use it to power two 150W amps and an effects processor. The unit is very light and easy to use as well as being quite clean. I used to use a marine battery but they are very heavy and cumbersome. The Lithium battery gets a very clean sound for me as well, even with the amp in overdrive mode, whereas the marine battery would produce a horrible square wave sort of “pweee” sound. The inverter and charger that I bought from Lithiumhub to use with the unit are very efficient and easy to use as well. I would definitely recommend!
