Ionic Lithium Deep Cycle Battery 12V100-EP4S

The best value 12V 100Ah lithium deep cycle battery on the market

The Ionic 12V 100Ah Lithium Deep Cycle Battery is the most competitively priced lithium deep cycle battery on the market and also comes with an industry best 5 year warranty.

World Class Safety Features

Ionic Deep Cycle 12V100-EP has 12 volts and a 100Ah 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.

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 Lithium Battery line has the best weight to power ratio on the market

At 6.7” (L) x 12.1″ (W) x 8.3” (H) and weighing only 28.0 lbs., the Ionic Deep Cycle 12V100-EP (Group 27) has the best size to power ratio of any deep cycle battery on the market. Group 31 sizing and dimensions are 6.5” (L) x 12.4″ (W) x 9.2” (H) at 28lbs and 38.2lbs with heater option. Connectors: 3/8th UNC Threads 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 100A and max discharge current is 100A / 350A(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.

    Excellent battery, would highly recommend to anyone. Customer service was very helpful and friendly and i received my unit right away. The app that connects with it is very user friendly and if very useful for keeping track of the battery life and how much it is getting used. Great company to do business with and will definitely be using them in the future.

    These Lithium batteries are the best quality out there. I have used mine (50 AMP) for going on their 6th season without 1 issue. The Bluetooth App is the bomb, it tells you everything about the battery, like a fuel guage, and my batteries are still charging 98% capacity. I use them in my bass boat and run a 36Volt trolling motor all day and they are not below 20-% at the end of the day. Another thing I like is the fast charge with my standard onboard charger. Regular marine batteries took about 6-7 hours to charge, these Ionic Lithium”s charge in about an hour. Thats awesome because I’m ready to go back fishing before I finish dinner ! The cranking battery I use is the 125 AMP. I run live well areators all day and 2 12″ Graphs and crank a Yamaha 250 SHO with no limits. I upgraded from the 100AMP to the 125Amp this season. I had 5 years on the 100 and it still remains at 98% capacity. If you want great customer care, the best lithium battery available, the best guarantee, Best Bluetooth App, then you will choose IONIC for your use. And one other thing the BEST PRICE availabl!! 5 stars from me!

    I put two 50 Ah and one 100 Ah in my boat and was amazed at the power they had and the weight of them over the Interstate battery’s i had been running , probably saved 175 lbs. of weight. i also was amazed how much faster my boat was, picked up almost 7 miles an hour .To me they are the stuff you dream about…….GREAT PRODUCT…….ICONIC IS THE WAY TO GO………

    I ran an X2 battery as well as the largest Diehard battery for years. I tried the IONIC 125 amp lithium battery from Lithium Hub and was impressed on how it performed. After running live wells , electronics and Powerpoles this battery started my Optimax better than any batteries I’ve used. Still had 95% power after day of fishing. Battery weighs only 34 lbs. vs 75 lbs. on the other batteries. Also the 50 amp trolling batteries performed really well. The Bluetooth app is great and lets you know what is going on with the batteries. Lithium Hub was very easy to deal with !!!

    It was nice to speak with the staff about before purchase to confirm I was ordering the battery I needed. Fast shipping and the price was right. One thing I appreciate more than anticipated is the Bluetooth parameter reporting. This eliminated a substantial amount of additional monitoring hardware in my installation. Using the battery for Solar PV storage.

    I have all 12 V batteries w/ cranking at 125 AHs and three 100 AHs for trolling. I had 50 AHs for trolling. I find them positive with charging and utilizing them through my terrains. I am aggressive when hunting fish especially when pre-fishing. The apps are good to help you track consumption. I recommend them due to price, functionality, & durability. My Bass Cat runs faster and maneuvers better w/ minus 240 lbs. I give Lithium Hub 10 stars w/ CS and product.

    Need to throw in some praise for RV use. I installed two 100ah Stark Power (old branding) lithium batteries three years ago to replace my two Interstate LA batteries. The performance improvement was incredible. With the LA batteries I could not run the heater through the night without dropping well below the safe 50% capacity level. Generator needed to run every day in cold weather. The greater useful capacity of the lithium batteries let me go several days without charging. I added a third Ionic battery last spring to increase the bank to 300ah and added a battery monitor to follow usage since my older batteries did not have the BT monitor. This whole camping season I did not need to run the generator once, using a 120w solar unit to help replace some of the used electrons. While the Ionic lithium batteries can be charged with a standard RV converter charger, I saw a marked improvement in performance with a change to a lithium specific charger. With this one change, I now have a power system that is truly carefree. The Ionic Lithium batteries have preformed well beyond my expectations. Top line performance at a reasonable price. Can’t beat that. Lithium Hub, you need to start pushing RV use.
