Ionic Lithium Deep Cycle 12 Volt 150Ah Battery with Heater
World Class Safety Features
The Ionic Deep Cycle Lithium Battery 12V150-EPH has 12 volts and a 150Ah capacity and is perfect for powering your deep cycle systems. You can use it as a starting – dual Lithium battery 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 starters batteries will work with outboard motors including Mercury and Yamaha.”
Built for Longer Lasting Reliable Power
The Ionic Deep Cycle Battery has a cycle life of 3,000 cycles or about 10 calendar years. Our lithium 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-4 to 140°F (-20 to 60°) and a charge temperature range of 32 to 113°F (0 to 45°C). This battery automatically detects if it’s too cold to take a charge.
The Ionic Lithium Deep Cycle line has the best weight-to-power ratio on the market
At 13.3” (L) x 7.3″ (W) x 8.5″ (H) and weighing only 33.1 lbs., the Ionic Lithium Deep Cycle 12V150-EPH has the best size-to-power ratio of any deep cycle battery on the market. Connectors: Dual 3/8-16 UNC Threads allow you to install the battery in any direction, unlike lead-acid batteries (they’re fixed). Ionic Lithium Deep Cycle Batteries’ monthly self-discharge rate is 1-3%. Compare that to lead-acid batteries’ about 30%. The recommended charge voltage is 14.2 V – 14.6 V, and the BMS Discharge Current Cut-Off voltage is 360A (5s). The Maximum Continuous Discharge Current is 100 A@25°C, and the Peak Discharge Current is 360A (5s). You can charge it with with solar chargers. You can charge it with most traditional lead-acid chargers that don’t have “Desulfate” mode, provided the current levels do not exceed lithium battery charge specification. A traditional lead-acid charger reaching 14.2 – 14.6 volts can fully charge the battery. Chargers that don’t exceed 13.6 volts will only charge the battery to 50% capacity or less.
Product Dimensions
Group 31 measurements
Widest spots. The battery does taper on the very base bottom.
Length: 13.3 in => 339mm
Width: 7.3 in => 185mm
Height: 8.5 in => 215mm
Can I use this as a starter battery for my Yamaha or Mercury outboard?
Yes. The IC-12V150-EPH is engineered as a dual-purpose battery and can start outboard motors up to 250hp from Yamaha or Mercury. It delivers 1,600 cranking amps (CA) and has proprietary BMS software designed specifically to handle the overcharging quirks of Yamaha and Mercury outboards.
Will installing this aftermarket lithium battery void my outboard motor warranty?
No. Under the Magnuson-Moss Warranty Act, a vehicle manufacturer cannot legally void your warranty for using an aftermarket part unless they can prove the part caused the failure. Ionic batteries are engineered with BMS software specifically compatible with Yamaha and Mercury 250hp motors, so they won’t trigger the overcharging issues that would cause warranty concerns.
Will this battery fit my existing Group 31 battery tray?
Yes. The battery measures 13.3″ × 7.3″ × 8.5″ (339 × 185 × 215 mm) and weighs 33.1 lbs — sized to fit standard Group 31 battery trays. The dual 3/8-16 UNC terminals also let you install in any orientation, unlike fixed lead-acid batteries.
Can I connect multiple batteries in series or parallel for a larger system?
Yes. You can connect up to 4 batteries in series (for 24V, 36V, or 48V systems) and as many as needed in parallel to expand capacity. See our Series and Parallel Connection guide for wiring diagrams.
What chargers are compatible with this battery?
Compatible chargers include Ionic, NOCO Gen Pro, Dual Pro PS/Auto, Minn Kota Precision, Pro Mariner / Pro Tournament Elite, Stealth, Troll Bridge DC, and Power Pole. Any LiFePO4-compatible charger that reaches 14.2V – 14.6V (and stays within the 100A max charge current) will work. You can also use most traditional lead-acid chargers that reach 14.2 – 14.6V — just avoid any with a “Desulfate” mode. Chargers that don’t exceed 13.6V will only charge the battery to 50% capacity or less.

Your input is very much appreciated. Share it with your friends so they can enjoy it too!
I bough 2 of this batteries .My Mercury 300 hp start with no issue and all day my live well and fish finder 12" screen works and only use 10%of capacity. I am very happy and recommend this product.
We purchased 4 12V for our RV. They have been amazing we had one issue that we tracked down to a fuse on the cords but that was not from the batteries other than that is has been an amazing adventure with our off grid life.
The 150Ah Dual Purpose Battery w/ Heater is my 4th Ionic battery. The 3 100ah work flawlessly on my trolling motor, and I expect this one will also perform well. I am powering my front electronics from this battery, and it handles the load well. A 16", 2 12", Active Target, and 360 pull a lot of amps, and I have plenty of power remaining after a full 10-hour day. Delivery was super-fast, and the battery was a drop-in replacement of my AGM.
Starting with Jason, the sales manager, he was extremely helpful and ultimately sold me the battery. The battery is crazy light and installation was easy. I think I had a couple questions once I had it installed and the team was right there to answer. I use this battery as the main house battery. I went to an electric only lake and ran my entire boat all day plus 4 12” units, FFS, 360. Still had power at 60% at the end of the day. Thank you
