SEOUL, July 25 (Reuters) - South Korean battery firm LG Energy Solution (LGES) 373220.KS on Friday posted a 152% rise in quarterly profit, driven by front-loaded demand as some customers stockpiled batteries ahead of potential U.S. tariffs.

The company, which supplies Tesla TSLA.O, General Motors GM.N and Volkswagen VOWG_p.DE among other automakers, reported an operating profit of 492 billion won ($358.73 million) for the April-June period, versus a 195 billion won profit a year earlier.

That compared with a 298 billion won average forecast by LSEG SmartEstimate, which is weighted toward analysts who are more consistently accurate.

($1 = 1,371.5000 won)
