Features
Not all lithium batteries are created equal. All RELiON Batteries use the safest and most stable components, including a LiFePO4 cathode and a built-in Battery Management System (BMS). The BMS ensures a long lifetime, safe handling – and high-accuracy State of Charge (SOC) calculations.
Temperature Tolerant
Lithium batteries can handle a wide variety of conditions and are even 2.5x more efficient at low temperatures than lead-acid while being able to safely operate up to 149°F (65°C).
Lightweight
RELiON lithium batteries provide more power than lead-acid batteries and are typically half the weight. Boosting both performance and agility on the water.
Constant Power
Full power is available throughout discharge. Voltage does not drop like lead-acid.
Eco-Friendly & Safe
RELiON lithium batteries are the ultimate clean energy. No gassing, no fumes, and no pollution. Enjoy reliable power, while protecting the environment, using these non-hazardous batteries.
Maintenance Free
Plug, play, and charge. No watering, no corrosion.
Partial State of Charge Tolerant
Partial state of charge, known as PSOC, which is a killer of lead-acid batteries, does not affect performance or battery life of a lithium battery. Sometimes batteries don’t get fully charged, or they regularly operate in a partial state of charge. Either way, you can count on RELiON lithium batteries living a long and productive life.

Fantastic battery and peace of mind. Just finished 3 week trip and never worried about battery. Super fast recharge while driving & solar. Minimal drain during day use. Should have switched to Relion years ago. Thank you

The 36 volt set up with the RB-100 keeps my trolling motor running at peak performance from daylight till dark without any loss in power. The RB100-HP as my main cranking battery that powers all of the electronics (3 including power hungry live scope) live wells, talon shallow water anchors, lights, trim ect. has performed beyond expectation. At the end of a tournament day with everything running I still have 13.2 volts. The recovery time for charging is lighting fast and the huge weight difference switching from heavy AGM's has increase the fuel economy with my outboard and overall performance of my boat. Glad I made the switch to Relion!

We just installed our 2 lithium 100ah batteries. It was simple to install and worked right out of the box. We also bought a Victron BMV-712 and it had no issues recognizing and reading your batteries.

I never send in reviews but I have to in regards to this purchase. These batteries have exceeded my expectations. I'm a bass fisherman and need a power supply I can depend so all I have to think about is fishing. These batteries maintain a high output which means my 3 sonar units never go down. 360 transducer never gets distorted which it did with lead acid as the power drained down below the threshold. My trolling motor acts like it picked up 5 lbs of thrust. It is strong all day. I can run my live wells, aerator, oxygenator etc without a concern ill have enough power. My only regret is I should have switched over sooner! Thank you!

I looked at many different lithium batteries, deciding on Relion. Purchased three of these for my trolling motor and very impressed with their performance. The weight of these batteries are amazing, making it so easy to install. The number one reason for going with this brand was the help and excellent customer service from Brad. He offers good advice on type battery needed and always willing to follow up when there is a question.

After researching different brands for a couple of years, I took a chance on the ReLion RB-100 for my 24v and 36v bass boats. Since I can’t take both boats out at the same time I am using three batteries for both boats. The bass tournaments I fish usually drain any lead acid battery in the 10 hr day. I bought the ReLion battery monitor to keep track of charge/discharge and after fishing a couple tournaments now I can say that I am impressed. Battery monitor has not got below 35% no matter how hard I run the Trolling Motor. We fish only river tournaments in the MO ozarks. The trolling motor is almost always running at 50-70% 80lb or 112lb. The only problem with these is that they WILL NOT start your motor. You will need the RB100-HP which has 800a peak discharge instead of the RB100 200a discharge. Happy spending.

What Our Customers Are Saying
"In a truck camper, weight matters a great deal. My lithium batteries are half the weight of the lead-acid batteries with twice the power since I can use them down to around 10% or more of their capacity as opposed to 50% capacity on the lead-acid batteries. If I were to recommend RELiON batteries to a close friend, I would say that they're a good, safe bet that are far superior to any lead-acid/AGM batteries."

How does your battery compare to the Canbat lithium battery?
Like the weight reduction, have not used them much so reserving commit for a later date. Shipping was fast Freight company contacted me for delivery time frame. Customer service was first class and quick.

Lithium batteries are rated for peak current (20°C/68°F for 5-10 seconds) instead of cold cranking amps (0°C/32°F for 30 seconds). The RB100 is rated at 200A for 5-10 seconds.
How come there is no CCA specs?
