The RELiON 12V 100Ah dual purpose lithium battery is the perfect replacement for a group 31 sized battery. Weighing in at only 30 lbs it’s a lightweight alternative to lead-acid and one of the most popular lithium batteries. The 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 the 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.
The RB100-HP surpasses expectation by being versatile, compact and more powerful than its lead-acid counterparts. It’s the perfect combination of size and capacity to fit many applications including, RV, marine, solar energy systems and more.
RELiON lithium iron phosphate (LiFePO4) batteries provide more energy for high consumption than traditional lead-acid batteries. They also offer fast charging and discharging, high efficiency and a longer cycle life – plus no maintenance!
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.

Wee Expert Tip - Use a Victron SmartShunt battery monitor to conveniently read out battery parameters, like state of charge, time to go, historical information and much more via a Bluetooth connection to the VictronConnect App on your phone (or tablet).
FAQCan I use my existing lead-acid battery charger (Wet, AGM or Gel) to charge RELiON lithium iron phosphate batteries?
- Most likely, yes. RELiON lithium batteries are very charger-friendly. Most chargers today have a lithium charge profile, which is what RELiON recommends using. AGM or gel charge profile chargers will work with RELiON batteries. RELiON does not recommend the use of a flooded charge profile with their batteries. These chargers may reach the overvoltage protection limit and disconnect. It won’t damage the battery but will likely result in charger faults. See RELiON's Lithium Charging Instructions for more details.
- Some key differences to consider:
- RB100 battery: the standard group 31 lithium iron phosphate battery
- RB100-D battery: a DIN size battery, commonly used in Europe.
- RB100-HP battery: a dual-purpose battery, which provides a higher peak current than the standard RB100.
- RB100-LT battery is designed specifically for cold weather charging.
