The story

Jonas Troest Petersen fights under the nickname “Duracell.” The Danish MMA fighter from the Borup area is affiliated with FighterZone in Roskilde. His competitive journey began on the international amateur stage and continued on professional cards in Denmark and the United Kingdom.
During the 2014 IMMAF World Championships in Las Vegas, Troest defeated Hafed Mrani by decision. The following day, he lost to Kacper Formela by split decision. His professional debut came in 2018 at Danish MMA Night, where he defeated Espen Kolltveit by guillotine in 35 seconds.

After bouts at UK Fighting Championships, MMA Galla became an important part of his career. He recorded victories there over Konstantinos Leonidou, Matej Simic, and Zemaray Afzali. Against Afzali, he bounced back with a decision victory after an earlier defeat. He then fought Aria Azarnoosh and Ali Al-Jasim at Dominance FC.
