World Class Safety Features
Ionic Deep Cycle Lithium Battery 12V150-EP has 12 volts and a 150Ah capacity and it’s perfect for powering your deep cycle systems. You can use it as a starting – dual Lithium battery comparable to 1,600 cranking amps for 250hp engines. 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 12V 150Ah batteries used as starter batteries have been engineered to work with overcharging issues that different outboard marine motors have. Ionic 12V 150Ah batteries used as starter batteries will work with all outboard motors with alternators including Mercury and other leading brands.
Built for Longer-Lasting Reliable Power
The Ionic Deep Cycle Battery has a cycle life of 3,000 cycles or about 10 calendar years, providing enough power to sustain energy for onboard electronics and accessories. Our lithium batteries have a usable capacity of 99% compared to 50-60% for traditional lead-acid batteries. Ionic 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. As a side note, this is a dual purpose lithium battery built primarily for marine, RV, floor sweepers, lift gates, UPS systems, and solar energy storage, it is not a car battery.
The Ionic Lithium Deep Cycle Line has the Best Weight-to-Power Ratio on the Market
At 12.55” (L) x 6.5″ (W) x 9.22″ (H) and weighing only 34.2 lbs., the Ionic Lithium Deep Cycle 12V150-EP has the best size-to-power ratio of any deep cycle battery on the market. It is ideal both for powering trolling motors and marine accessories like fish finders, and starting your boat or RV. Connectors: 3/8 UNC Threads allow you to install the battery in any direction, unlike lead-acid batteries (which are fixed). Ionic Lithium Deep Cycle Batteries’ monthly self-discharge rate is 1-3% compared to lead-acid batteries which are about 30%.
The max charge voltage is 14.6V and the discharge cut-off voltage is 10.5V. The max charge current is 80A and the max discharge current is 100A / 500A(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.

Widest spots. The battery does taper on the very base bottom.
Length: 12.52 in. => 12 1/2 in. => 318mm
Width: 6.496 in. => 6 1/2 in. => 165mm

Height (studs top): 9.2 in. => 9 13/64 in. => 233mm
Note: Compared to a traditional lead acid battery, this lithium battery is lighter and more compact (and drop-in ready!), making it much easier to handle and install and helpful for cutting weight.
Not only that, the Bluetooth feature allows you to monitor the battery status remotely on your phone. This is a significant advancement in solar, RV and marine batteries (and beyond), as it helps you keep track of your battery’s performance and health with a few taps, even while navigating.
