Aircraft; Procedure
I came close to 2 [helicopters] on departure in ZZZ. When I was taxiing out they called in a flight of 5 inbound for [Runway] XX. I responded that I was taxiing for [Runway] XX and I would hold short for them. While I was holding short; they flew overhead; and I only saw 3 definitive lights. 2 [helicopter] with white lights followed by 2 [helicopters] with barely recognizable dim green lights; and one in the back with a red beacon. They called clear on [Taxiway] XX as I watched the white and red lights clear the runway I could not see the dim green lights after they passed in front of me because they were barely recognizable. I made a radio call that I was departing on [Runway] XX. I taxied onto the runway with all my lights on; did not see any aircraft lights on the runway; and started my departure roll. Just as I was about to rotate I felt wake turbulence and decided to abort. I saw a black silhouette pass on my right; then another one. I cleared the runway. They claimed that they didn't call clear of the runway and that they had all their lights on. There was a pilot at [FBO] that told me they only saw 3 sets of lights and all appeared to have cleared the runway. He saw me abort and was confused as to why I did because he never saw the other 2 [helicopters].
Pilatus Single Pilot reported coming close to 5 helicopters that were landing/taxiing while taxiing out for departure.
