Our RB100-HP is a dual-purpose 12V, 100 Ah lithium battery. Our HP Series batteries are high performing dual purpose deep cycle batteries that can handle both starting and cycling. The RB100-HP has increased peak amps over our standard batteries. This increase in peak amps can be used to start motors, electric start generators and other high amp draw devices. After starting, the battery can double as a house battery providing power for peripherals, accessories and other onboard needs.


RELiON’s HP Series batteries are a perfect compromise between the unique demands of starting service and deep cycling, low amp draw service. The RB100-HP is a powerhouse that is also versatile and compact enough for use in many marine applications including bass boats and shallow bottom boats.


The RB100-HP features installation flexibility and no maintenance over the life of the battery. It maintains consistent power and is equipped with an M8 terminal type and a built-in battery management system (BMS).

PRODUCT REVIEWS

Tom P.

I now have 4 of the 100HP 12 batteries. So far I love them. I using them to replace my 4 8d AGM batteries and I just love that fact that they charge very fast compared to the AGM batteries. Less generator time when on the hook.

Justin H.

So far these are great. Starts the big motor every time and lasts all weekend for the trolling motor.

Michael B.

This battery is fantastic! It solved all of my power needs for my bass boat. Between multiple sonar units and PowerPoles, the cranking battery just could not keep up. This battery cranks the motor with no effort, even after a full day of fishing. It charges super fast and is as reliable as they come. Very happy with my purchase.

Larry C.

I have been using this battery for almost 2 years with no problems. My boat has a 12" Solix at bow and 12"solix at helm plus 360 imaging and live-wells on this battery. It is also the cranking battery for a Merc 250 8 cylinder. I fish weekly tournaments and have never had it fail to start the engine. I also use 3 Relion 100ah batteries for the trolling motor. Expensive, but in the long run well worth it. When I was using AGM batteries I had to replace them every 2 or 3 years.

Brad G.

I have been out on the water with it 4 times so far. It has worked perfectly. I trolled all day long running both large graphs, playing radio and running live well pump. After about 9 hours a started my main motor and it turned it over effortlessly. Love it! Also took 2 group 31 batteries out of my boat reducing over 100 pounds!

Brian W.

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!

Rusty L.

Very impressed with the power this battery has to run all the electronics and still maintain enough amps to crank the motor. Worked with Brad Green and he went the extra mile to get me a battery in such a short amount of time before the tournament. Customer Service like this will make me always come back to RELiON for my next purchase.

Paul Duval

I replace 8 12V 92Ah AGM batteries in the house bank on my Nautitech 441 catamaran with 4 RB100HP batteries. This was all that was available in Grenada during lockdown. Not only did it lighten my boat by about 400lbs, the bank had greater capacity and faster charging than the old AGM’s. Overnight the SOC would drop to around 85% depending on load (refrigerator, lights, fans) and with 3x180W solar panels would reach 100% before noon. I was also able to power my watermaker for 1hr in the morning and still reach 100% by 3pm

Jim T.

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!

Charlie Y.

Great batteries. I have a few of them now...I'm a boat guy..bass boat...they're good trolling motor batteries as well as a cranking battery.

I have a Lance truck camper that is equipped with a Cummins Onan 2500 genereator. Most 100 ah Lithium batteries are not starting batteries, so I was concerned about using Lithium to start my on-board generator. When I discovered that ReLion has a dual purpose battery (RB100HP), that can be used for starting, it was exactly what I was looking for in Lithium. I installed two of them in my camper and they are working perfect!

Les Sage

I have a Lance truck camper with a built in Cummins Onan Generator. The RB-100HP is the perfect Lithium battery for my application. Since this battery has a very high peak output, it will easily start my generator without any issues. I researched most of the Lithium batteries and nobody else had something comparable in a 100ah batttery (6/20). I am very pleased with the quality and performance! Great company to work with for technical help.

Jacob C.

Haven't had it long, but definitely impressed.

Larry Fadaol

I looked at many different lithium batteries, deciding on Relion. Purchased one of these for my Yamaha 250 SHO and works great! 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.

RB100-HP Batteries Power Boondocking Lifestyle

RB100-HP Batteries Power Boondocking Lifestyle

"Like many others, we prefer to boondock in our RV. After becoming aware of the advantages of Lithium batteries, I started researching which Lithium batteries would be good fit for my Lance camper.

Several RV technicians cautioned me about using a Lithium battery to start my onboard generator. They explained Lithium batteries are not “starting batteries” and that one would probably not start my Cummins 2500 generator. However, I discovered that RELION makes a special Lithium battery that will start my generator with no problems. It is RELION’s RB100-HP battery.

Consequently, I installed two RB100-HP batteries in my camper and they have been working perfect. Not only do they easily start my generator, but these remarkable batteries have practically doubled the capacity of my previous batteries and take less time to re-charge.

Combining RELION’s batteries with solar, has given me the ability to boondock more places without having to worry about electrical needs."
