The RB100-HP is a lithium iron phosphate battery, built for starting and cycling marine and RV applications. The RB100-HP has increased peak amps for starting motors, electric start generators, and other high-amp-draw devices – plus, it doubles as a house battery, powering peripherals, accessories, and more. The RB100-HP was the first lithium battery to be evaluated and approved for use with select Mercury Marine® outboard engines.
