The Best Lithium Starting Battery For Your Boat

"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!" - Brian W.
