Product Description

Ionic 24V Lithium Battery – 24V50-EP

World Class Safety Features

The Ionic 24V Lithium Battery 24V50-EP has 24 volts and a 50 amp hours capacity. It’s perfect for powering your deep cycle systems. Ionic Deep Cycle has an internal microprocessor controlled battery management system (BMS). It monitors the key operational parameters during charging and discharging.  (Like voltages, currents and internal temperatures.) Ionic Deep Cycle Batteries can be hooked up as many needed in parallel.

This 24 Volt Battery is 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. They have 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).  If batteries are too cold to take a charge, it automatically detects it.

The Ionic Deep Cycle Lithium Battery line has the best weight to power ratio on the market

At 12.5” (L) x 6.5″ (W) x 8.5” (H) and weighing only 27 lbs., the Ionic Deep Cycle 24V50-EP . 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 29.2V 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 28.8-29.2V will allow the battery to be fully charged. Chargers that do not exceed 27.2V will only charge the battery to 50% capacity or less.

Just the right fit and so far so good!

I won’t be using my new trolling motor for another month or so but the IONIC 24V fit perfectly upfront in my Alumacraft Classic. Never in a million years did I think I would spend that kind of money on a Lithium battery but at 72 the arms got too heavy. If the Ionic last for at least 6-7 years I’ll be please. Oh yeah, its cool to use the App to check condition.

24v 50amp good but will need second

Great battery app is hit or miss.. but will show soc and that's all you need. I have a 16ft deep v boat with an 80 pound trolling motor.. at full speed (walleye fishing erie 2.5-2.8 speed ) will only last 3 hours or so. But bass fishing inland lakes with spot lock on and simple trolling will last all day
