What is the High Performance Series?

HP Series batteries offer the capability to deliver a burst of high current for a short period of time. These current requirements are typically necessary to start a boat, generator motor, or an air conditioning compressor. Depending on the application, a single RELiON HP battery can be used for starting then double as a house needs power source. These batteries provide the high power needed to start your motor or generator, even after hours of powering your electronics. 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 12V 100Ah lithium battery that can be used in many marine applications including bass boats and shallow bottom boats. Another popular use for the RB100-HP is coupling with a generator and an automatic generator start (AGS). An AGS monitors your batteries and when a predetermined state of charge is reached will tell your generator to turn on so your batteries may begin charging.

"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 battery (6/20). I am very pleased with the quality and performance! Great company to work with for technical help."

Frequently Asked Questions

Can I have more than one HP battery connected?
Our HP series are extremely versatile and if one by itself doesn’t have enough capacity can be hooked with other HP or standard RELiON 12V batteries in parallel.
Do I connect HP batteries connected in series or parallel?
Unfortunately, the HP series cannot be hooked in series.
Can I connected HP batteries with other 12V batteries?
RELiON HP series batteries can be hooked in parallel with other standard RELiON 12V models to provide enough power to run an electric trolling motor while the HP model provides enough amps to crank the boats gasoline-powered motor.
Can I use my existing lead-acid battery charger (Wet, AGM or Gel) to charge RELiON lithium iron phosphate batteries?
In general, lithium batteries are charger-friendly. Most chargers today have a lithium charge profile, which is what we recommend using. In most instances, AGM or gel charge profiles will work with our batteries. We do not recommend the use of a flooded charge profile with our batteries. These chargers may reach the overvoltage protection limit and disconnect. It won’t damage the battery but will likely result in charger faults. Before using any charger with RELiON batteries it is best to first verify the charge profile is within our specifications, which can be found in our Charging Instructions. Be sure to read over our charging guide in detail prior to charging your RELiON battery.
How much can I discharge my RB100-HP dual-purpose battery and still start my engine?
The RB100-HP can be discharged up to 70% (30% state of charge) and still start most engines.
Is it okay to connect my starting battery in parallel with one of my RELiON lithium trolling motor batteries to assist with starting if needed?
Yes, however, if you do so, it is required that you use a switch to isolate each battery so that they can be charged separately with a multi-bank charger.
