Ionic Lithium Deep Cycle 12 Volt 125Ah 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 900A 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 outboard motors including Mercury and Yamaha.”
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 / 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.

Most existing lead chargers will work with our Lithium batteries. We have had some issues with Duel Pro Chargers working with our Lithium Batteries. We do sell chargers as well that can be seen here. https://lithiumhub.com/product/ionic-four-bank-charger/

I bought three of the Ionic 125 ah batteries for my bass boat, three battery trays and the 4-bank charger. I’ve got to say I’m very impressed from the quick shipping, expert packaging, and all around support for the products. The blue tooth app is a great tool for keeping track of your batteries. The weight I saved in my boat is just plain crazy. Haven’t got a single negative thing to say about Ionic products. Can’t recommend them strongly enough.

I purchased two of the Ionic 125AH blue tooth Li-ion battery’s a little under a year ago . I purchased them to create a large power station in my 86 VW Vanagon to power a mocha machine , pellet smokers, LED lighting for the purest of glamping comforts my mind can think of. Now I’m ordering two more 125AH batteries to create the same setup in my WW2 1946 Karr trailer . Setting up a system like this is very complex which is why the customer service and engineers helped me figure out the best solution for my application/power needs. The blue tooth app. Is very useful and easy to use as well. Thank you Jeff In customer service for helping me with all my questions and guiding me in the SAFE/right direction .

This is the second 12V125EP purchased for my RV. While going down the road I charge the batteries from Victron Energy Orion-Tr 12 I 12-9 isolated DC/DC converter. I have both batteries wired in parallel. Before I connected both batteries, I partially discharged one of the 12V125-EP batteries to see how well the two batteries would balance. For the first few minutes, the fully charged 12V125-EP discharged at a rate of 25 Amps into the partially discharged battery. After about 5 minutes both batteries were balanced. Then I fully charged both batteries using a Progressive Dynamics 9245C charger / converter with a PD92201 remote charge pendant. The remote charge pendant manually controls the boost mode placing the charger at 14.6V, ideal for fully charging the 12V125-EP batteries while connected to power at a camp ground. The blue tooth app is used to monitor state of charge. Once the batteries are fully charged, my RV has a switch to disconnect the batteries from the charger / converter. These lithium batteries, unlike lead acid, have a very low self discharge rate. I have done a short term test not charging the two batteries for 2 weeks. This is to test how well balanced both are. After 2 weeks, both batteries are at 99% charge.
Amazing!
With 80% DOD, this is like having 400 AH house batteries compared to the old lead acid.

Both the 12V 100Ah and 125Ah batteries work as dual batteries. The 12V125Ah is recommended to run graphs and start engines up to 250hp. The CCA rating is 900A. All of our batteries have a 5 year warranty with them.

Yes, most regular lead acid charges will charge our ionic lithium batteries if the charger is under 15V.

Love this Battery! I run an HDS16 , 12 Live and a Garmin with Livescope. No voltage issues whatsoever. Would recommend this battery to anyone. Also love the 3 50ah TM batteries. Can easily run all day with all of them and fires up my Verado without any concerns.

Starting a new year with my IONIC 125AMP cranking battery. It has been bullet proof, never letting me down. I run 2 Lowrance Live 12s, livewell full power all day and have never even had a glimpse of a problem. Just the best to be had. Cranking a Yamaha 250 HP SHO 4 stroke. Plus my IONIC trolling batteries are the absolute best.

What can I say – I can say a lot. The first time out I fished a 9 hour tournament. We caught a keeper within the first 5 min and ran both livewell pumps all day long. On my boat I also run 3 units, 360 Mega and a radio have to have some music. After putting the boat on the trailer I checked the Ionic 125ah cracking battery and it was sitting at 58% enough to fish another full day tournament. At the ramp a few people were checking out the new boat and was really impressed with the live of all 4 Ionic batteries.
Thank You
Corey Bradley
