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.

      We would recommend using our 12V100Ah or the 12V125Ah depending how large and many graphs you are running. Either battery can be used as s dual purpose battery up to 250hp outboard.

    • MK

      The 12V20Ah battery will not be large enough for a 24ft lb thrust motor. I would suggest our 12V30Ah or 12V50Ah batteries for a smaller trolling motor that should run 3-5 hours depending on how you use it.

  5. Question

    Carlin Jacobs

    I have a Can Am Outlander XMR 1000. Very close dimensions to this 12V 20Ah option. Would this battery provide enough power to crank the bike and suffice as a battery for my bike?

      The 12V20Ah is not used as a starting battery. I will not provide enough cranking amps for engine starts.

  8. Question

    John Kimm

    Can this be used for the battery-powered golf trollies? Golf trolly like Batcaddy X8R, for 18 holes round, about 6 miles in the total distance carrying 70 lbs of the total load(includes cart, battery, and golf bag. Is this the same battery as “Stark Power Lithium “SP-12V20-EP”?
