Our take on the Ionic 12 Volt 100Ah Lithium Deep Cycle Battery

The Ionic 12V 100Ah is a lithium iron phosphate deep-cycle battery built for marine, RV and off-grid use. It weighs about 70% less than a comparable lead-acid battery and is rated for 3,000 to 5,000 charge cycles, roughly a decade of regular use. A built-in battery management system monitors voltage, current and internal temperature, and blocks charging below freezing. It carries an 11-year warranty. Against flooded and AGM rivals it delivers more usable capacity and far longer life, though it costs more up front and needs a lithium-compatible charger.

About the Ionic 12 Volt 100Ah Lithium Deep Cycle Battery

This is a 12 volt, 100Ah lithium deep cycle battery. It weighs 28 lbs, about 70% less than comparable lead-acid batteries. It is rated for 3,000 to 5,000 cycles and needs no maintenance. It is a drop-in, plug-and-play replacement, and it can be installed in any direction.

A microprocessor-controlled Battery Management System monitors voltage, current and internal temperature during charging and discharging. It provides cell balancing, low-voltage and overvoltage protection, short-circuit protection, power terminal cut-off and recovery, and built-in cold weather protection. The Ionic Blue Batteries app shows the battery's real-time status over Bluetooth.

The battery is used for marine, RV, floor sweeper, lift gate, UPS and solar energy storage applications. It is rated at 900 CCA and can be used as a starting battery for Yamaha or Mercury motors up to 200 hp. For a 24 volt trolling motor, use two batteries. Any number of batteries can be connected in parallel, and up to four in series.

Questions and answers

How does it compare with a 100Ah AGM battery?
It weighs far less and delivers close to its full 100Ah, while AGM should only be run to about half. It also lasts several times longer in cycles, so the higher upfront cost spreads over many more years.
Can I charge it with my existing charger?
Only if the charger has a lithium LiFePO4 profile. Older lead-acid or AGM chargers can overcharge it or stop short of full charge, so check the charger's settings before use.
Can it be charged in freezing weather?
No. The BMS blocks charging when the internal temperature is below freezing to protect the cells. Discharging in the cold is fine, but bring it above freezing before recharging.
What can a 100Ah lithium battery run?
It suits RV house loads, trolling motors, fish finders and small solar setups. A 100Ah bank runs modest 12V loads for hours, but high-draw appliances like air conditioners need more capacity.
Does it need maintenance?
No. There is no water to top up and no equalizing charge. Keep the terminals clean and store it partially charged in a moderate temperature for long breaks.
What is in the box?
The battery itself. You supply the charger, cabling and mounting hardware, and you should confirm terminal type and group size fit your tray before installing.
