Product Description

Ionic Lithium Dual Purpose Deep Cycle 12 Volt 125Ah 1100 Cranking Amp Battery

World Class Safety Features

Ionic Deep Cycle Lithium Battery 12V125-EP has 12 volts and a 125Ah capacity and is perfect for powering your deep cycle systems. Can be used as a starting – dual Lithium battery comparable to 1,100 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 125Ah batteries used as starters batteries have been engineered to work with overcharging issues that different outboard marine motors have.  “Ionic 12V 125Ah batteries used as starters batteries will work with all outboard motors with alternators including Mercury and other leading brands.”

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 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 12V125-EP has the best size to power ratio of any deep cycle battery on the market. Connectors: 3/8 UNC Threads 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 10.5V. Max charge current is 80A and 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.

New Lithium package

Purchased new complete boat package and was a good and easy installation. Have the mobile app and working good to see the battery status. I’ve been on straight nights for 6 weeks and within two weeks I hope to get boat on water to finally do some fishing! Thank you!����

I have not put them in my boat yet as it’s in the shop being worked on. I look forward to hooking my live scope up to them and give me the power to last all day long. I will let you know how they work. Thanks

Wow what a difference

Just wanted to share my experience I just bought 4 12v 125AH ionic batteries for my lung fiberglass boat and wow what a difference in just three weeks. There should be no reason why people don’t change their lead acid batteries out once they’re used up. The experience is unreal from the weight loss, the super convenient charging app on your phone. And unreal how long the charge last compared to acid cell batteries. There’s no comparison point blank. I guide on Lake Texoma seven months out of the year with another boat that I have and five months traveling around other lakes in the country. I fish probably 150 guided trips on Texoma and another 75-90 on other lakes for my enjoyment. I have lead cell in my guide boat currently as soon as their dead out they go Ionic will definitely replace them. I’d be proud to display any kind of advertisement for these batteries. I’ve been been guiding on Texoma for what will be my 34th year in 2024 and still going strong.

Best money spent.

Just buy it. If you want peace of mind just get it I was skeptical of buying one and was just going to stay with a lead battery. But JUST DO IT..
