Product Review: Relion RB100-HP LiFePO4 Marine Battery
Weighing in at a svelte 29.8 pounds (in comparison, my older 27-series flooded lead acid battery was over 50 pounds), the tapered frame of the ReLION RB100-HP Group 31 fits neatly into a 27-series battery tray, so making the swap was a breeze. This 100-amp hour battery is rated at 12.8-volts, so it will produce 1280 watt hours of capacity.
