World Class Safety Features

Ionic Litihum Deep Cycle 12V50-EP has 12 volts and a 50Ah capacity and is perfect for powering your deep cycle systems. Ionic deep cycle batteries have 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 deep cycle batteries can be hooked up 4 in series and as many needed in parallel.

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

At 6.5” (L) x 7.7″ (W) x 7.0” (H) and weighing only 14.3 lbs., the Ionic Deep Cycle 12V50-EP has the best size to power ratio of any deep cycle battery on the market. Connectors: M6 screws 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 50A and max discharge current is 50A / 170A(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.

    The best valued Lithium battery available. The Highest Quality Lithium avaialable. The only Bluetooth Lithium available. This battery is phenominal. I use 3 in series for a bass boat trolling motor. They run 8-10 hours on 50% trolling speed and at the end of the day are only down 15-20% and the power is constant, it doesn’t loose power, so I don’t have to dial the trolling motor up in speed at all. Just set it and go. The small size is great also. It gave me back a lot of used up space for lead acid batteries. And another important thing is the weight lost from getting rid of the lead acid. These batteries don’t corrode and stay clean and don’t heat and gas like the lead acid batteries, so much nicer! The only way to go. I highly reccomend this battery. Just plain awesome!

    I bought this to use as an auxiliary battery for my VW Vanagon Westfalia. It fits under the driver’s seat with room to spare. The BMS works with a standard battery isolator. I haven’t gone on any extended camping trips, but it’s worked well so far. I’ve used it a couple times to assist the starting battery when that was low on charge.

    The customer service for Lithium Hub is outstanding. I received my two 50 amp batteries with in days of the order. The Bluetooth feature allows constant monitoring of the batteries condition. I purchased for use on my kayak. They have proved to be lightweight and long lasting.
    If you have questions they have answers.

    I use it in conjunction with a sine wave inverter to power two 150W guitar amps various effects for outdoor music performance. I have only used it twice so far but the performance has been great. The signal is very clean, possibly even more that standard AC. I had tried a few other systems but they all created a line hum that would not go away. That and/or they were much to bulky and cumbersome. Both the battery and the inverter are presentable as well, they look neat. The battery is also very light, which is a huge plus.

    Great batteries! I have three 50AH on my ultrex and have fished from daylight to dark and they were still at 64%. They are compact, lightweight and charge really fast.

    Best Lithium’s for the money. High quality, light weight, ample power for all day tournaments or fun fishing. The Bluetooth feature to monitor the batteries health is amazing. Will buy again. Highly recommended.

    First tournament outing today. 24 volt Ultrex running 5-10 on the speed setting. Fished 7-2:15 Used 25% with an amp draw of 42 running the trolling motor wide open. Very impressed. Fished into high winds with no resistance. No complaints

    These batteries are phenomenal! I needed to replace my trolling motor batteries. I bought these on recommendation from several others. After looking at the cost of good lead acid batteries and their past performance, or lack there of. I decided to spend the extra few bucks on these.
    These things are worth every penny! From trolling motor performance to the amount of runtime. Not to mention increase in speed out of the boat by shedding 150lbs worth of weight. I highly recommend these batteries to anyone looking to up their performance all the way around.

    Amazed at the size and performance of these little batteries! I bought 3 of the 12v 50Ah and I can’t run them down! In fact, when one of the banks went out on my charger I switch to 24V on my Lowrance Ghost TM and still can’t run these batteries down. Customer service is fantastic as well!

      If your charger like the Minn Kota Precision, chargers 14.2V to 14.4V your charger will work. Chargers charging over 15V should not be used as well as chargers with “desulfation” or balancing mode. Lithiumhub does sell ionic chargers as well that can be found here: https://lithiumhub.com/product/ionic-four-bank-charger/
