What LiPo to use?

So I recently got a DarwinFPV CineApe25 as my first quad, but I forgot adding batteries to the basket.. On their website, the manufacturer lists matching 4S packs with 15.2V, 850mAh. Now I can't find 15.2V packs on Amazon (dont wanna wait another 3 weeks). Can I just throw 4S Tattu R-Line packs at it, running at 14.8V, or will it cause any issues? Thanks in advance!
